Antibody surveys suggesting vast undercount of coronavirus infections may be unreliable – Science
Surveying large swaths of the public for antibodies to the new coronavirus promises to show how widespread undiagnosed infections are, how deadly the virus really is, and whether enough of the population has become immune for social distancing measures to be eased. But the first batch of results has generated more controversy than clarity. [Related pre-pub study]

Inequities in COVID-19: why does COVID-19 hit some areas harder than others? – FLARE
As the COVID-19 outbreak progresses in the U.S., it is becoming clear that communities are not equally affected. Racial and socioeconomic disparities in incidence are apparent in highly impacted communities, such as New York and Boston, as well as outside the Northeast, in places like Charlotte, Chicago, and the Navajo Nation.
In addition to disparate incidence of disease, disadvantaged communities face higher rates of co–morbidities such as diabetes and hypertension that are known to contribute to poor outcomes in COVID-19. Some of these communities with elevated rates of high-risk health conditions have greater proportions of uninsured residents, which may lead to under-financed and under-resourced healthcare systems, ill-prepared for a COVID-19 patient surge.

If you’ve been infected with the COVID-19 coronavirus and managed to survive, you may be wondering how long your symptoms will last and how long you will remain contagious.

Solving the Mysteries of Coronavirus with Genetic Fingerprints – New York Times

As the coronavirus outbreak consumed the city of Wuhan in China, new cases of the virus began to spread out like sparks flung from a fire. Some landed thousands of miles away. By the middle of January, one had popped up in Chicago, another one near Phoenix. Two others came down in the Los Angeles area. Thanks to a little luck and a lot of containment, those flashes of the virus appear to have been snuffed out before they had a chance to take hold. [If you hit a paywall at the link, try here]
