A retrospective analysis of stored respiratory samples shows one patient could have been infected with SARS-CoV-2 weeks before the coronavirus was thought to have arrived in France, but a critic of the result questions whether the sample was contaminated.

Assembling the first COVID-19 test kits in the same room as coronavirus material, along with other practices that didn’t follow protocol, made the tests unusable, officials say.

Vaporized hydrogen peroxide is the most effective decontamination method for masks that had been exposed to the coronavirus in a recent study.

Studies from serum samples could transform our understanding of the spread of COVID-19, but what antibodies alone say about immunity is not yet clear.

By studying influenza in mice and cells, researchers identify a glucose metabolism pathway critical to the dysregulated immune response that kills many infectious disease patients, including those with COVID-19.

The recent cases come just as Democratic Republic of Congo was set to declare the outbreak’s end.

An inflatable biosafety laboratory may help meet the global need for testing infrastructure during the COVID-19 pandemic.

Several studies have indicated that SARS-CoV-2 might be spread through air, but not all experts are convinced.

Researchers report that dogs, pigs, chickens, and ducks did not easily become infected.

Rhesus macaques can be infected with SARS-CoV-2, leading primate center scientists to try to prevent outbreaks in their colonies, especially as experiments on coronavirus start.

Disease experts have largely focused on how we got to where we are now with coronavirus infections. Improved data collection and sharing can enhance projections of what’s to come.

A preprint indicates that coronavirus transmission from surfaces is possible, but does not provide evidence that this has occurred in the COVID-19 pandemic.

Manufacturing sites are ramping up production of reagents needed to isolate SARS-CoV-2’s genetic material—a key step in testing for the virus.

It takes a median of five days after infection to get sick, and patients shed the most coronavirus particles early in the illness, according to two new reports.

Contact tracing and genetic testing reveal how SARS-CoV-2 circulated among individuals for weeks, especially in the US, before being detected.

The pathogen appears to have come from wild animals, virologists say, and there are no signs of genetic manipulation in the SARS-CoV-2 genome.

Current methods to detect infections of the novel coronavirus rely on identifying particular genetic sequences, but new assays are being developed to meet the growing demand for rapid answers.

Administration officials have given contradictory statements about how COVID-19 will affect the US, and it is not clear who is leading the infectious disease response effort, critics say.
