From a hospital on the edge of the Navajo Nation to the suburbs of the nation's capital, front-line medical workers in novel Coronavirus hot spots are struggling to keep up with a crushing load of patients while lockdown restrictions are lifting in many other parts of the US. Governors are starting to slowly reopen some segments of their local economies, pointing to evidence that COVID-19 deaths and new hospitalisations are peaking or starting to recede in their states. But a government whistleblower warned on Thursday that the US faces its "darkest winter in modern history" unless leaders act decisively to prevent a rebound of the virus.

Coronavirus outbreaks are testing public health networks in pockets of the US. Among them is a suburb of Washington, DC. The head of a hospital system in Maryland's Prince George's County said the area's ICUs "are bursting at the seams." Meanwhile, a civil rights group's lawsuit claimed the county's jail failed to stop an "uncontrolled" outbreak and isolated infected prisoners in cells with walls covered in feces, mucus and blood.
