The U.S. coronavirus outbreak crossed a grim milestone of over 3 million confirmed cases on Tuesday as more states reported record numbers of new infections, and Florida faced an impending shortage of intensive care unit hospital beds.

Authorities have reported alarming upswings of daily caseloads in roughly two dozen states over the past two weeks, a sign that efforts to control transmission of the novel coronavirus have failed in large swaths of the country.

California, Hawaii, Idaho, Missouri, Montana, Oklahoma and Texas on Tuesday shattered their previous daily record highs for new cases. The biggest jumps occurred in Texas and California, the two largest U.S. states, with more than 10,000 each. About 24 states have reported disturbingly high infection rates as a percentage of diagnostic tests conducted over the past week.
