Evidence of a post-Thanksgiving surge should be emerging this week, a Harvard epidemiologist said, advising people who gathered together to get tested or assume they’re infected.

The Harvard Center for Population and Development Studies and Center for Geographic Analysis worked with Microsoft to create a live tracker that monitors the status of COVID cases, broken down by congressional district, to help officials develop testing and vaccine deployment strategies in their areas.

Experts said the complex rollout of a coronavirus vaccine gives the U.S. a chance for a win after the virus gained the upper hand in its initial phase.

Barry Bloom from the Harvard T.H. Chan School of Public Health offers context about the news that two experimental vaccines appear to confer a high level of protection from the coronavirus.

Massachusetts General Hospital researchers examined six patients using a specialized magnetic resonance technique and found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain as patients who have suffered oxygen deprivation from other causes.

Harvard psychiatric epidemiologist Karestan Koenen said acknowledging that this Thanksgiving will be hard is a first step toward a meaningful holiday.

For COVID-19, the difference between surviving and not surviving severe disease may be due to the quality, not the quantity, of the patients’ antibody development and response, suggests a new study.

William Hanage, an associate professor of epidemiology at the Harvard T.H. Chan School of Public Health, offers key advice as the holidays approach.

Medical experts say a vaccine will be a key development in the fight against the coronavirus, but warned against thinking its deployment will mean the fight is over.

A new trial at Beth Israel Deaconess Medical Center is aiming to disrupt COVID-19’s attack early in its course by treating patients immediately after symptoms appear with a widely used antiviral drug that, if it works, could be rapidly repurposed to fight the coronavirus.
