(Bloomberg) -- The U.S. is “going in the wrong direction” in its effort to contain the novel coronavirus and daily case counts could more than double if behaviors don’t change, infectious-disease expert Anthony Fauci said Tuesday.

Pinpointing indoor gatherings, particularly bar scenes with lines out the door and patrons standing shoulder to shoulder, Fauci told a Senate panel that new cases of Covid-19 could rise to 100,000 a day, up from the current level of about 40,000.

Several southern and western states are seeing surging new case numbers, prompting some to put reopening plans on hold. Hospitalizations have increased in 12 states, Centers for Disease Control and Prevention Director Robert Redfield told members of the Senate health committee. Florida’s Miami-Dade County reported its highest numbers of hospitalizations, intensive-care patients and ventilator use in at least two months. In Houston, ICUs hit 97% of normal capacity on Tuesday.
