The so-called 614G mutation in the viral spike protein does not appear to cause more severe cases of COVID-19, but multiple studies indicate that it could be more contagious.

Thomas Stoeger of Northwestern University has previously studied scientists’ limited focus on certain genes. In a new study, he shows how these same behaviors extend into the science of COVID-19.

Half a year after infection, people who had recovered from COVID-19 had robust antibodies, along with traces of the virus in their gut, which may drive long-lasting immunity.

Patients’ viral loads are highest within five days of their first symptoms, emphasizing the need to isolate early to prevent transmission.

A CRISPR-based, paper-strip test developed by Indian researchers performs as well as real-time PCR in identifying the presence of SARS-CoV-2 and returns results within an hour.

An abundance of immunoglobulin antibodies, and a paucity of viral RNA, in breastmilk offer evidence that women can safely continue breastfeeding during the pandemic.

The results mark the second experimental COVID-19 vaccine to show high efficacy, but the study is not complete and the data have not been peer reviewed.

Whole genome sequencing of the virus infecting the farm animals showed that it spread from the workers to the mink and back, indicating that an animal could serve as a viral reservoir.

A study finds that β-coronaviruses don’t use the normal secretory pathway, a possible explanation for some aspects of COVID-19 pathology.
