Based on data from COVID-19 patients from Wuhan, China, that died as a result of the infection, researchers have identified many symptom commonalities the patients shared.
Structural mapping of both SARS and SARS-CoV-2, the virus that causes COVID-19, reveals an almost identical site on both coronaviruses to which the CR3022 antibody binds. This suggests a functionally important and vulnerable site for this family of coronaviruses.
SARS-CoV-2, the virus responsible for COVID-19, can linger for days in sewage and water systems and remain infectious. Researchers call for new studies to determine if current water treatment methods are efficient and effective at killing SARS-CoV-2.
Wearing face masks significantly reduced the amounts of airborne virus particles expelled from infected patients. Findings suggest surgical-style face masks could slow the transmission of coronavirus and influenza viruses.
Historical data from Flu Watch about other coronaviruses reveals they appear to have a seasonal pattern, with peaks occurring during winter. Only small amounts of other coronavirus infections were transmitted during the summer. The findings support the hypothesis that COVID-19 may have lower levels of transmission during the summer, but this may reverse during the winter months if there is still a large, susceptible population.
Preliminary results from a new model suggest the COVID-19 lockdown should last for more than six weeks. The advice is based on data which shows it takes countries almost three weeks to see a growth rate staying below 10% and doubling time over seven days. It takes a month to keep the growth rate under control and at 1%, and 45 days to achieve containment.
Compared to the virus that caused the SARS epidemic in the early 2000s, SARS-CoV-2, the virus responsible for COVID-19, has evolved new strategies to bind to cell receptors, resulting in tighter binding. A new study identifies key mutations that potentially enabled the animal-to-human transmission of SARS-CoV-2. The study mapped out important binding sites on SARS-CoV-2 for antibody drugs to act on. If new drugs can bind to the sites on SARS-CoV-2, they will block the virus out of cells.
People who use glucocorticoids, a class of steroids used to treat asthma and arthritis, are at higher risk of developing severe symptoms of COVID-19.
Implementing strong physical distancing measures across Europe to suppress the spread of COVID-19 has averted over 100,000 deaths, a new model finds.
Researchers have developed a new paper device that can be put into wastewater systems to detect COVID-19. The test works by picking up on biomarkers of the virus in feces and urine. The test can help monitor communities most at risk of the virus and help agencies to restrict the movement of the population at risk.
On Saturday, the FDA approved Houston Methodist to conduct transfused plasma therapy for the treatment of COVID-19. The plasma will be donated from recovered COVID-19 patients and transfused into those critically ill with the virus. Researchers have already begun recruiting donors in the Houston area who have recovered from coronavirus. The first donor was a patient in the Houston Metropolitan area who has been in good health for two weeks following COVID-19 infection.
In addition to physical distancing and improved personal hygiene practices, the seasonal moderation of relative humidity indoors could help slow rates of transmission for COVID-19. However, the virus can still be transmitted via contact and close proximity to those infected, regardless of the season, researchers warn.
