Reports of reinfection instead may be cases of drawn-out illness. A decline in antibodies is normal after a few weeks, and people are protected from the coronavirus in other ways.
How to safely reopen offices, schools and other public spaces while keeping people six feet apart comes down to a question mathematicians have been studying for centuries.
Four charts show how pooling samples from many people can save time or resources.
T cell reactivity against SARS-CoV-2 was observed in unexposed people; however, the source and clinical relevance of the reactivity remains unknown. It is speculated that this reflects T cell memory to circulating "common cold" coronaviruses. It will be important to define specificities of these T cells and assess their association with COVID-19 disease severity and vaccine responses.
Neural networks have been taught to quickly read the surfaces of proteins - molecules critical to many biological processes. The advance is already being used to create defenses for the virus responsible for COVID-19.
Didier Fassin is James D. Wolfensohn Professor in the School of Social Science at the Institute for Advanced Study. An anthropologist and sociologist, he was trained as a physician in internal medicine and public health, and focused his early work on the AIDS epidemic and health inequities.
