Cluster: COVID-19

A cluster of topics related to COVID-19. COVID-19 is the abbreviated name for coronavirus disease 2019, a respiratory disease caused by a novel coronavirus strain called SARS-CoV-2. COVID-19 was first detected in Wuhan City, China and the outbreak was declared a pandemic on March 11, 2020 by the WHO.

COVID-19 is the abbreviated name for coronavirus disease 2019, a respiratory disease caused by a novel coronavirus strain called SARS-CoV-2. COVID-19 was first detected in Wuhan City, China and the outbreak was declared a public health emergency of international concern on January 30, 2020 by the World Health Organization (WHO). On March 11, the WHO stated that the COVID-19 outbreak is characterized as a pandemic, meaning worldwide spread. Nonpharmaceutical interventions (NPIs) such as social distancing, quarantine, and school and workplace closure were put in place to slow the spread of the virus.

The SARS-CoV-2 virus, previously called 2019-nCoV, was described by researchers at the CAS Key Laboratory of Special Pathogens, Wuhan Institute of Virology, Center for Biosafety Mega-Science, Chinese Academy of Sciences by Peng Zhou and colleagues, led by Zheng-Li Shi.

COVID-19 treatments and vaccines

Remdesivir is an experimental drug approved by the US FDA on October 22, 2020 which has been shown to shorten the time to recovery from SARS-CoV-2 infection by interfering with viral replication.

There are no FDA regulated vaccines for prevention of COVID-19.Treatments in development for COVID-19 focus on three primary areas: symptoms, anti-inflammation, and anti-viral growth. Certain treatments (below) have been granted FDA emergency use authorization (EUA) for the treatment of COVID-19. EUA authorizations may allow unapproved medical products or the use of approved medical products for unapproved uses in an emergency to diagnose, treat or prevent serious or life-threatening conditions or diseases. Potential drug and vaccine targets include proteins, enzymes, processes that allow virus entry into cells or virus replication and immune system regulatory pathways.

Spike protein or S-glycoprotein targets

The SARS-CoV-2 virus gains entry into human cells through the spike (S) protein, also called S-glycoprotein, which binds to the ACE2 receptor of human cells. Spike proteins cover coronaviruses, the virus group which includes SARS-CoV-2, MERS, and SARS viruses, giving them their crown or corona appearance. Both the S-protein (S-glycoprotein) and the ACE2 receptor have protein modification called N-linked glycosylation that is important for the ability of the virus to gain entry and also plays a role in the virus evading immune detection.

Immune system targets

Drugs that calm or modulate the immune system could potentially prevent complications such as acute respiratory disease syndrome and acute lung injury that occur when the immune system overreacts to an infection. Anticytokine therapies target the overproduction of proinflammatory cytokines, referred to as a cytokine storm, that can lead to severe complications such as vascular hyperpermeability and multiorgan failure. An adequate inflammatory response must be maintained for the body to clear the pathogen.

COVID-19 potential treatments

The following COVID-19 treatments are experimental or in development unless otherwise specified. Treatments may have emergency use authorization from the FDA while still in an experimental stage. Some drugs designed and approved to treat other diseases are being tested for COVID-19.

Approved treatments

Remdesivir

Remdesivir received US FDA approval on October 22, 2020 for treatment of COVID-19. Remdesivir , a Nuc inhibitor drug that inhibits viral replication, was granted emergency use authorization by the FDA on May 1, 2020. Gilead announced the submission of their New Drug Application (NDA) for remdesivir to treat COVID-19 under the product name Veklury in August 2020. An expansion of the EUA issued on August 28, 2020 allows Veklury to be provided to hospitalized patients irrespective of disease severity. Ongoing Phase 3 Clinical Trials for remdesivir are NIAID ACTT-1 Trial, Gilead GS-US-540-5773 Trial and Gilead GS-US-540-5774 Trial.

Emergency Use Authorization (EUA)

Chloroquine

EUA for chloroquine phosphate and hydroxychloroquine sulfate was revoked on June 15, 2020 based on review of further scientific evidence.Hydroxychloroquine sulfate and chloroquine phosphate products were granted EUA authorization by the FDA on March 28, 2020. Chloroquine is a quinoline derivative and a drug in widespread use since 1945 for the treatment of malaria, autoimmune diseases, and other medical conditions. Chloroquine is being investigated to treat COVID-19 in the form of chloroquine phosphate or hydroxychloroquine sulfate which are sometimes referred to as chloroquine and hydroxychloroquine respectively.

COVID-19 convalescent plasma

Convalescent plasma to treat COVID-19 was issued EUA on August 23, 2020. At this time convalescent plasma had been used to treat 60,000 COVID-19 patients. Randomized clinical trials for COVID-19 convalescent plasma are ongoing. Convalescent plasma is donated similar to blood from individuals that have recovered from COVID-19 and contains antibodies against COVID-19.

Baricitinib in combination with remdesivir

The FDA issued an EUA on November 19, 2020 for the combination treatment of baricitinib together with the FDA approved drug remdesivir for treatment of suspected or laboratory confirmed COVID-19 in hospitalized adults and pediatric patients two years of age or older requiring supplemental oxygen, invasive mechanical ventilation or extracorpeal membrane oxygenation (ECMO).

COVID-19 vaccines

Emergency Use Authorization

Commissioner Dr. Stephen Hahn stated that the FDA may consider EUA of a vaccine before trials are complete. Director of the Infectious Diseases Division of Vanderbilt University Dr. David Aronoff and others voiced concerns about not waiting until clinical trials are complete and reviewed. The FDA issued guidance document for Emergency Use Authorization for COVID-19 vaccines in October 2020 which states that before seeking emergency approval, vaccine makers should follow trial participants for at least two months to rule out major side effects. CDC director Robert Redfield, vaccine developers and the FDA stated that a COVID-19 vaccine is unlikely to be widely available until the middle of 2021.

Conditional approvals

Gamaleya Research Institute of Epidemiology and Microbiology (Russia)

The Russian Ministry of Health issued a registration certificate on August 11, 2020 for a COVID-19 vaccine developed by the Gamaleya Research Institute of Epidemiology and Microbiology in Moscow, that had been tested in 76 people. The vaccine was dubbed Sputnik V. The certificate allows the vaccine to be given to a small number of citizens from vulnerable groups such as medical staff and the elderly. The certificate is similar to the FDA granting emergency use authorization. It is stipulated in the certificate that the vaccine cannot be widely used until January 1, 2021. It is expected that at this time larger clinical trials will have been completed. The certification of the vaccine received criticism for being premature and potentially exposing those who receive the vaccine to unnecessary risk. The vaccine is manufactured by Binnopharm in Zelenograd. The vaccine uses an adenovirus carrier engineered to carry the spike protein of SARS-CoV-2.

Results from small-scale Phase 1/2 clinical trial published in The Lancet show that neutralizing antibodies to SARS-CoV-2 were generated in dozens of subjects with mostly mild side effects. A T cell response was reported within 28 days. A large-scale Phase 3 trial received approval on August 26 which is expected to enroll 40,000 volunteers.

China National Biotec Group Company (CNBG)

In China an experimental COVID-19 vaccine was approved for use in individuals working in high risk professions on July 22, 2020. The vaccine was developed by Sinopharm’s China National Biotec Group Company (CNBG). At the time the vaccine had completed Phase 3 clinical trials in UAE, Peru, Morocco and Argentina.

Beijing Institute of Biotechnology/ CanSino Biologics

The vaccine called Ad5-nCoV that was developed by the Beijing Institute of Biotechnology and the company CanSino Biologics was approved by the Chinese government for use for military personnel on June 25, 2020. The vaccine is being tested in clinical trials in China and in Canada in a collaboration between CanSino Biolgics and the National Research Council of Canada (NRC). In the vaccine development, a proprietary HEK293 cell line of the NRC and part of the work of Dr. Frank Graham (McMaster University, Canada).

Vaccine manufacturing

Operation Warp Speed (OWS) is a partnership between the US Department of Health and Human Services, which includes the CDC, FDA and NIH, and the Biomedical Advanced Research and Development Authority (BARDA) and the Department of Defense (DoD). The goal of OWS is to produce and deliver 300 million doses of safe and effective vaccines. Initial doses aim to be available by January 2021 and OWS has a broader strategy to accelerate development, manufacturing and distribution of COVID-19 countermeasures.

OWS funded Janssen, Moderna and AstraZeneca, Novavax, Pfizer, Sanofi and GlaxoSmithKline supporting COVID-19 vaccine development and large-scale manufacturing. OWS funded Regeneron supporting their COVID-19 anti-viral antibody treatment. Task orders with Emergent BioSolutions and Texas A&M University and FUJIFILM are aimed to advance US manufacturing capabilities. Grand River Aseptic Manufacturing (GRAM) in Michigan, USA received a contract with OWS for fill and finish manufacturing of critical vaccines and therapeutics.

Exothera is a contract development and manufacturing organization (CDMO), launched by Univercells in March 2020 plans to work on vaccines for COVID-19 through supporting vaccine innovators and providing manufacturing services.

In Canada vaccine production may take place at the Human Health Therapeutics Research Centre in Montreal. The Canadian government has signed deals with Moderna, Pfizer/BioNTech, Novavax and Janssen to reserve millions of doses of COVID-19 vaccine.

Vaccine delivery and storage technology

Microneedle vaccine patch

Vaxess Technologies is developing a COVID-19 vaccine that can be delivered with their drug patch delivery system (MIMIX) allowing self-administration of vaccines or therapeutics without the need for refrigerated storage or syringes. The system uses silk protein fibroin to stabilize and allow the vaccine to be stored and transported at room temperature. The vaccine and MIMIX system combination is a skin patch that can be administered at home. Silk-based tips are embedded into the skin. Over a period of weeks the fibroin protein controls the rate that the vaccine is released and diffuses into the body.

Vernardi, a biotech startup has VaxiPatch technology under development in a partnership with BARDA. VaxiPatch was invented by Daniel R. Henderson, CEO of Vernardi and will undergo preclinical testing at University of California, Davis.

BARDA also funded research at University of Connecticut under Assistant Professor Thanh Duc Nguyen and Associate Professor Steve Szczepanek to develop their vaccine microneedle patch for COVID-19.

Oral delivery

Esperovax is partnered with BARDA for development of their oral cellular delivery technology called Egress RDTM mRMA which can allow for lower cost, self-administration of vaccines.

COVID-19 diagnostics and screening

Types of SARS-CoV-2 tests

COVID-19 diagnostic testing is performed on sputum, nose, and throat swabs. In early March 2020, governments restricted COVID-19 testing to central health agencies or a few accredited laboratories for a real-time reverse-transcription PCR (RT-PCR)-based protocol selected by the WHO. Reverse transcription means a reverse transcriptase enzyme is used to convert RNA template to cDNA before PCR amplification which produces a large number of copies of the cDNA. Real-time PCR is sometimes called quantitative PCR (qPCR or qRT-PCR). Tests that use PCR are also referred to as nucleic acid amplification tests (NAAT) as they amplify deoxyribonucleic acid (DNA). The COVID-19 real-time RT-PCR test detects the presence of the E gene of SARS-CoV-2, coding for the envelope surrounding the viral shell and the gene for the enzyme RNA-dependent RNA polymerase. Once samples are received in a laboratory, it takes 24-48 hours for results. The tests were confirmed to be accurate with whole genome sequencing. The US Centers for Disease Control and Prevention (CDC) has an RT-PCR assay that includes primers for the nucleocapsid phosphoprotein in the virus shell and for the RNA-dependent RNA polymerase gene. In the UK, COVID-19 testing is done by accredited laboratories. In the US COVID-19 testing was initially done exclusively by the CDC which later began sending out RT-PCR test kits to state health laboratories. Some clinical tests on sale in the US were made available under CLIA waivers, which regulate the facility where the tests are conducted, rather than the tests themselves. The FDA announced on February 29 that CLIA-certified labs do not need to obtain emergency use authorization (EUA).

The FDA issued a policy March 16, 2020 to accelerate the availability of COVID-19 diagnostic tests which includes the following: Each state takes responsibility for tests developed and used by their laboratories and labs developing tests engage directly with state authorities; the FDA does not intend to object to the distribution of tests after validation and during preparation of an EUA request; Recommendations are provided for developers of serological tests which identify antibodies or proteins in the blood in response to infection.

Many diagnostic or screening methods are in development and still need verification. The aim is to develop diagnostic tests that could potentially be deployed more widely in hospitals and clinics and with quicker turn-around times. The purpose of diagnostics and screening is not only for patient isolation but also for overall monitoring of the spread of COVID-19. The Foundation for Innovative New Diagnostics (FIND) is a global non-profit organization concerned with the development and delivery of diagnostics for diseases that affect poor populations. FIND is collaborating with the WHO and a third-party, referral laboratory to conduct an independent evaluations of SARS-CoV-2 diagnostic tests in order to verify manufacturer’s claims, and establish diagnostic accuracy. Results will be shared with the global health community.

As of April, 2020, the majority of COVID-19 nucleic acid tests use real-time RT-PCR that targets ORF1b, ORF8, nucleocapsid (N), spike (S) protein, RNA-dependent RNA polymerase (RdRP) or envelope (E) genes of SARS-CoV-2. Samples tested are usually swabs from the upper respiratory system but it is possible to use serum, stool, ocular secretions or saliva. There are nucleic acid amplification tests that use CRISPR and isothermal amplification.

Besides detecting viral RNA, other diagnostic tests being developed to detect viral protein or antibodies produced by a person infected with SARS-CoV-2 using antibody-based methods or serological tests such as ELISA and lateral flow immunoassay. Antibodies may be used as probes to detect viral protein. For serological tests, antibodies produced by a person exposed to the virus are detected in blood samples. Antibodies are still found in patients after they recover from the illness.

The US FDA issued an EUA for the serology point-of-care (POC) test, Assure COVID-19 IgG/IgM Rapid Test Device in July 2020 for certain laboratories and reissued the EUA in September 2020 for use with fingerstick blood samples in POC settings like a doctor’s office or urgent care centers without the need for sending samples to a central lab. The WHO supports the use of tests for SARS-CoV-2 antibodies at a population level or in specific groups to help understand the risk associated with infection and data about the percentage of people with detectable COVID-19 antibodies. It is not known if people with SARS-CoV-2 antibodies are immune to secondary infections. Antibody tests can check if a person has previously been infected with SARS-CoV-2 but are not recommended to diagnose current infection because it may take 1-3 weeks for the body to produce detectible antibodies.

Viral load and disease severity

In real time PCR, cycle threshold (Ct) is the number of cycles for the fluorescent signal to exceed background level. Ct levels are inversely proportional to the amount of target nucleic acid, which is the amount of SARS-CoV-2 virus present, also known as viral load. Higher viral load and lower Ct has been correlated with disease severity, lung lesions with margins not easily differentiated and changes in follow-up CT (computed tomography) in patients with COVID-19 pneumonia. Patients with severe COVID-19 have been reported to have a higher viral load and longer virus-shedding period compare with mild disease.Another research study from China showed no correlation between viral load and disease severity. Viral loads in nasal swabs between symptomatic and asymptomatic individuals were not significantly different in an Italian study. In addition to real-time RT-PCR, digital PCR (digital RT-PCR) has been applied to studies on viral load to study disease progression.

COVID-19 research

COVID-19 sequencing and analysis

Sequencing the genetic code of SARS-CoV-2 from different patient samples is used to understand how the virus changes over time. For example, how it moved from a disease affecting animals to a human disease and how it became infectious in humans. Besides SARS-CoV-2, sequencing of related viral genomes from different contexts such as wild animal populations would be part of this line of research. Such research can prevent future outbreaks. By understanding the conditions that enabled SARS-CoV-2 to appear, a future virus may be prevented from following similar path.

  • Arbor Biosciences offering free kits for sequencing virus samples
  • GenapSys provides affordable next-generation sequencing machines
  • Illumina and IDbyDNA collaborated to provide next-generation sequencing workflows focused in microbiology and infectious disease
  • NVIDIA offers NVIDIA Parabricks Genomics Analysis Toolkit which provides GPU-accelerated genomic analysis
  • MGI Tech Co., Ltd. provides DNBSEQ-T7, a sequencing platform that can generate 1-6Tb of high quality data per day

Distributed computing projects

Folding@home launched a program in March 2020 to assist researchers around the world who are working on finding a cure and learning more about the COVID-19 outbreak. The initial wave of projects have been used to simulate potentially druggable protein targets from SARS-CoV-2 virus, and the related SARS-CoV virus, of which there is much more data available.

Other distributed computing projects include:

  • Rosetta@Home
  • Neocortix Cloud Services provides ARM support to Coronavirus distributed computing applications
  • BOINC
  • SETI@home

Immune response to COVID-19

Herd immunity

Herd immunity threshold estimates of around 10-20% were calculated when variation in individual susceptibility or exposure were taken into account for their mathematical modelling. Individual variation means that the presence of individuals that are more susceptible or more exposed are infected and removed from the susceptible subpopulation earlier and intensifies the deceleration in incidence. If the population were homogeneous or were vaccinated randomly, HIT would be estimated to be around 65-80%.

COVID-19 Biomarkers

  • C-reactive protein (CRP)
  • Patients with severe COVID-19 show lymphopenia (lymphocytopenia) with drastically reduced numbers of CD4+ T cells, CD8+ T cells, B cells and natural killer (NK) cells.

Data mining

Virtual drug screening

Southwest Research Institute (SwRI) has virtual screening software which it used to evaluate two million drug compounds agianst SARS-CoV-2. SwRI is partnered with Texas Biomedical Research Institute and their Rhodium software can scan 250,000 drug compounds using machine learning techniques.

Oak Ridge National Laboratory (ORNL) used its supercomputer to identify 77 small-molecule compounds as potential SARS-CoV-2 drugs which are likely to bind the novel coronavirus main spike protein which could prevent it from infecting cells.

Insilico Medicine is using an AI-based drug discovery pipeline to identify drug molecules that could target 3C-like protease. 3C-like protease is a SARS-CoV-2 protein that is a target for potential drugs because it has a central role in the viral replication cycle. A portion will be tested by Insilico Medicine and the remainder of the potentially useful structures will be published on the company website and available to the public (https://insilico.com/ncov-sprint/).

Materials and products related to COVID-19 prevention

According to available evidence, the SARS-CoV-2 virus is transmitted between people through close contact and droplets produced by sneezing and coughing. The SARS-CoV-2 virus was initially reported to not be transmitted by airborne transmission, but hundreds of scientists urged organizations such as the WHO to address airborne transmission in an open letter outlining emerging evidence, which culminated in a National Academies workshop on airborne transmission of COVID-19. Preventative measures include: hand hygiene with alcohol-based sanitizers or soap and water; avoiding touching eyes, nose and mouth; coughing or sneezing into elbow or tissue; wearing a medical mask if you have symptoms and hand hygiene after disposing of mask; maintaining social distance of 1 m from individuals with respiratory symptoms. In indoor environments, ventilation, filtration and air disinfection have been suggested to decrease potential airborne transmission. See COVID-19 transmission dynamics and COVID-19 protocols for more information on disease transmission and mitigation strategies respectively which include nonpharmaceutical interventions (NPIs) .

Protective mask recommendations

Masks can be used as personal protective equipment (PPE) to keep the wearer of the mask from breathing in SARS-CoV-2 virus. Masks are also used as a respiratory source control where the aim is the protect others from exposure to exhaled viral particles. Standards, protocols and methods for testing masks are found on the Mask Testing Protocols page.

Health care setting

The WHO has guidelines that recommend health care workers cover their mouth and nose with surgical masks and the CDC put out instructions for health care workers to wear N95 masks (N95 respirators). N95 masks are thicker and fit more snugly around the mouth and nose, blocking smaller particles than surgical masks. Both types of masks help prevent the spread of droplets from a cough or sneeze from reaching the mask-wearer’s mouth or nose. During the SARS coronavirus outbreak a study found that any type of mask or respirator reduced the risk of infections in health care workers by 85 percent. The CDC recommends that health care workers wear a respirator, also called an N95 mask, when around potential COVID-19 patients, which filters out more particles than a surgical mask. The CDC has a list of N95 masks approved by the National Institute for Occupations Safety and Health (NIOSH).

Infected patients who wear surgical masks are less likely to spread infection to others. The CDC instructed hospitals to request a patient wear a surgical mask if they have a fever or respiratory illness, recently traveled to Wuhan or have come in contact with someone who traveled there.

Masks for the general public

The purchasing of protective face masks by the public is feared to cause a shortage for health care workers during the COVID-19 pandemic. In addition to healthcare workers, a shortage of protective masks would slow scientific research on treatments and vaccines to SARS-CoV-2 since personnel need to be protected from the pathogens that they work with in the lab. For healthy asymptomatic individuals, who are not healthcare workers or caring for patients at home, wearing of a face mask was initially not recommended by the WHO. The WHO stated on February 27, 2020, “The capacity to expand PPE production is limited, and the current demand for respirators and masks cannot be met, especially if the widespread, inappropriate use of PPE continues”, referring to surges in global demand driven by misinformation, panic buying and stockpiling. The WHO changed their stance in June 2020 to state that those over 60 or with medical conditions should wear a medical -grade mask when in public when physical distancing is not possible and that the general public should wear three-layer fabric masks in those situations. The WHO advised governments to encourage mask wearing on public transport, in shops or other confined areas.

The CDC initially recommended that the general public not wear face masks unless they are sick or caring for a person who is sick. However, on April 3, 2020, the CDC recommended that the general public voluntarily wear a facial covering when out in a public space where social distancing guidelines are difficult to maintain. The CDC published guides for how to make a variety of face masks using common materials. 2013 Research on influenza transmission suggests that homemade facial coverings and masks made from household items like 100% cotton t-shirts, scarves, and tea towels can block some aerosolized bacteria and viruses, but they are not as effective as commercially available surgical masks. The paper states that "an improvised mask should be viewed as the last possible alternative if a supply of commercial face masks is not available, irrespective of the disease against which it may be required for protection."

Various countries or region of countries mandated masks to be worn in public spaces to slow the spread of COVID-19. In the United States a nation-wide, federal-level mask order is not possible due to the sovereignty of U.S. states. Accordingly, U.S. states specify their own local policies and regulations around wearing masks. Some states require that masks be worn in certain public settings (such as inside businesses) while others have enacted no such requirements.

For more information, see Surgical mask.

Manufacturers of face masks, surgical masks, and respirators (including N95)

Other personal protective equipment

For medical staff, in addition to masks, personal protective equipment (PPE) includes faceshields, gowns, bouffant caps and gloves. For more information go to Personal protective equipment.

Hand sanitizer

Hand washing is recommended over the use of hand sanitizer, but alcohol-based hand sanitizers provide some benefit against the spread of SARS-CoV-2 and are recommended for use when hand washing is not available. Both hand washing and alcohol-based hand sanitizers target viral envelopes. The increased purchasing of hand sanitizer during the COVID-19 pandemic has led to a shortage of alcohol-based hand sanitizer. Numerous distilleries in Canada and US distilleries have begun manufacturing hand sanitizer.

Chemical disinfection

An analysis of 22 studies concluded that human coronaviruses such as SARS, MERS and endemic human coronaviruses (HCoV) can persist on surfaces like metal, glass or plastic for up to 9 days. The study found that the viruses can be inactivated within 1 minute by surface disinfection procedures with 64-71% ethanol, 0.5% hydrogen peroxice or 0.1% sodium hypchlorite. Biocidal agents such as 0.05-0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate were found to be less effective.

The botanical oil Citriodiol and other compounds that contain p-menthane-3,8-diol (PMD) show antiviral properties against SARS-CoV-2.

Vaporized hydrogen peroxide

VHP is commonly used to decontaminate rooms, but it has been shown to be effective in sterilizing N95 masks without degradation of their performance. The systems usually use about 1000 ppm VHP, so some amount of evaporation is needed to allow the levels to drop below the NIOSH recommended level of 1ppm.

Environmental monitoring

Chai Bio will release a test that can be used with swabbing of areas like door handles and hard surfaces in the environment for SARS-CoV-2 testing. The test is intended for detection of the novel coronavirus in schools, senior centers, first responders, hackerspaces and community labs, public health departments and individuals. The BeagleBoard.org Foundation is working with Chai to make machines and test kits available in communities and makerspaces through board donations and has interest in promoting the technology around the world.

Droplet digital PCR (ddPCR) was used to test for SARS-CoV-2 viral RNA in aeorsols collected on gelatin filters in patient and medical staff areas at Renmin Hospital of Wuhan University, Wuchang Fangcang Field Hospital and public areas in Wuhan.

UV sanitizing devices

UV sanitizers use ultraviolet C (UVC) light which kills bacteria and viruses.

CleanSlate UV is a Toronto-based company that produces devices that sanitize items with UV light. Their UV light devices are used in hospitals to for staff to sanitize stethoscopes, badges and phones.

PhoneSoap is a Utah-based company that produces UV devices for cleaning and charging items such as phones, smart watches, keys, and tablets.

Xenex Disinfection Services is a company that provides ultraviolet disinfectant robots. Their technologies kill bacteria, viruses, and other microorganisms in hospital rooms, emergency departments, and ambulances. They have provided robot systems to Japan, Thailand, Singapore, South Korea, Italy, and Houston.

Far-UVC light

Conventional UVC light sources are a hazard to humans due to being carcinogenic and cataractognic. Far-UVC light generated by filtered excimer lamps emitting in the range of 207-222 nm wavelength inactivates bacteria and viruses without harming exposed mammalian skin. Far-UVC has strong absorbance in biological materials and cannot penetrate the outer layer of human skin nor the outer tear layer on the outer surface of the eye. Far-UVC can traverse and inactivate bacteria and viruses because they are typically at dimensions of microns or smaller. UVC was shown to inactivate airborne aerosolized H1N1 influenza viruses by researchers at Columbia University in 2018. The authors propose the use of very low dose-rate far-UVC overhead light in indoor public locations as a tool to reduce the spreading of airborne-mediated microbial diseases.

Robots and drones

UVD Robots developed by the Denmark-based company UVD Robots ApS are UV disinfecting robots that have been deployed in hospitals in China to help reduce the spread of the novel coronavirus. UV-C light is emitted to kill viruses and bacteria.

XAG is an agricultural technology company whose agricultural robots and drones have been adapted for testing scenarios to spray disinfectant to reduce the spread of COVID-19 and have been deployed in Guangzhou. High concentrated disinfectants can be sprayed from drone nozzles or robot jet sprayers and diluted with moisture in the air and potential targets include hospitals and schools.

Textiles and fabrics

Sonovia is a textile company that developed an anti-pathogen fabric that was sent to labs in China to be tested for use as a preventative measure against spread of COVID-19.

Antimicrobial coating

There are a number of antimicrobial coatings that are effective against certain viruses but have not yet been tested against SARS-CoV-2.

Multilevel Antimicrobial Polymer (MAP-1) developed at Hong Kong University of Science and Technology (HKUST) with Chiaphua Industries kills viruses, bacteria and spores. MAP-1 can be made into hand sanitizers, paints, coatings, and incorporated into air and water filters, clothing and surgical masks.

BioCote - antimicrobial coating company.

Extracorporeal membrane oxygenation (ECMO)

Critical COVID-19 cases may also show multiorgan and systemic manifestations such as sepsis, septic shock and multiple organ dysfunction (MOD). In addition to respiratory support extracorporeal membrane oxygenation (ECMO) may be necessary. ECMO is a machine similar to a heart-lung by-pass machine used in open-heart surgery. The device pumps and oxygenates the patient’s blood outside the body so that the heart and lungs can rest.

Infectious disease tracking

BlueDot is an AI company that tracks, contextualizes and anticipates infectious disease risks. BlueDot’s system identified an article in Chinese on Dec. 31, 2019, about “pneumonia of unknown cause” and issued an alert to its clients almost one week before the U.S. Centers for Disease Control and Prevention and the World Health Organization issued their public alerts.

Drive-through COVID-19 testing

Drive-through clinics in Goyang South Korea allow people to stay in their cars as sample are taken from their noses and throats from staff in protective clothing. Samples are tested on site and the user receives a phone call or text message of their result and placed in isolation. The UK is also opening COVID-19 drive-throughs.

Verily, a subsidiary of Alphabet, the parent company of Google, is developing plans for a website for Americans to find screening tests for COVID-19 and direct them to drive through clinics.

Mobile apps related to COVID-19

Corona 100m is an app in South Korea that alerts users if they are within 100m of a location the government marked as a high-risk area for COVID-19. The app uses public government data and can see the date a patient was confirmed with the disease, demographic data and their location history.

The Japanese medical advice company Agree, offers a free app for limited time that allows users in Japan to consult with doctors about their symptoms, which prevents overtaxing medical centers.

Apple is evaluating coronavirus apps to prevent the spread of misinformation and had reportedly rejected apps that are not from recognized institutions like governments or hospitals.

GYANT is an AI-enabled Healthcare chatting application for diagnosis. In March 2020, Gyant launched a free COVID-19 Emergency Response Assistant. It uses AI chat to check for COVID-19 symptoms and pertinent risk factors, then navigates patients to appropriate health system resources and care settings.

On March 13th, 2020, K Health (an AI-powered health app) began offering free virtual primary care for COVID-19, including unlimited access to U.S. doctors free for 14 days.

Curai Health, Carbon Health, and Babylon Health are digital health care providers that offer Covid-19 assessments via mobile or desktop.

No-contact food delivery

Many food delivery companies are adding "no contact" delivery as an optional component of their service. If a customer elects for no contact or "contactless" delivery, there is no direct contact between the customer who ordered the food and the driver who is delivering it.
