Protective antibodies persist for months in survivors of serious COVID-19 infections
People who survive serious COVID-19 infections have long-lasting immune responses against the virus, according to a new study led by researchers at Massachusetts General Hospital (MGH). The study, published in Science Immunology, offers hope that people infected with the virus will develop lasting protection against reinfection.

Mask mandates shown to significantly reduce spread of COVID-19
A new study by Simon Fraser University (SFU) researchers has found clear evidence that wearing a mask can have a significant impact on the spread of COVID-19. The researchers, from SFU's Department of Economics, have determined that mask mandates are associated with a 25 per cent or larger weekly reduction in COVID-19 cases.

Previous infection with other types of coronaviruses may lessen severity of COVID-19
Being previously infected with a coronaviruses that cause the "common cold" may decrease the severity of severe acute respiratory syndrome coronavirus (SARS-CoV-2) infections, according to results of a new study. Led by researchers at Boston Medical Center and Boston University School of Medicine, the study also demonstrates that the immunity built up from previous non-SARS-CoV-2 coronavirus infections does not prevent individuals from getting COVID-19.

Nitric oxide a possible treatment for COVID-19
Researchers at Uppsala University have found that an effective way of treating the coronavirus behind the 2003 SARS epidemic also works on the closely related SARS-CoV-2 virus, the culprit in the ongoing COVID-19 pandemic. The substance concerned is nitric oxide (NO), a compound with antiviral properties that is produced by the body itself. The study is published in the journal Redox Biology.

Researchers call for loss of smell to be recognized globally as a symptom of COVID-19
Four out of five people experiencing the recent loss of smell and/or taste tested positive for COVID-19 antibodies - and of those who tested positive, 40 percent did not have cough or fever, reports a new study in PLOS Medicine by Prof. Rachel Batterham at University College London and colleagues.

VirScan offers new insights into COVID-19 antibody response
A tool designed to detect viral history in a drop of blood has gotten an upgrade in the age of COVID-19. VirScan, a technology that can determine which of more than 1,000 different viruses have infected a person, can now also detect evidence of infection from coronaviruses, including SARS-CoV-2.
