As the United States reached its third consecutive day with a record number of new reported coronavirus infections, officials were urgently rethinking their strategies to head off new infections.

The U.S., which leads the world in total confirmed cases and deaths, reported more than 45,000 new infections on Friday, according to a Times database. Before this week, the country’s largest daily total had been 36,738 on April 24.

Globally, countries reported more than 191,000 new infections — a single-day record as the total number of cases neared 10 million. India’s caseload surged past 500,000 on Saturday.

At least six U.S. states — Florida, Idaho, Kansas, Oregon, South Carolina and Utah — reported their highest one-day case totals, and Dr. Anthony S. Fauci, the country’s top infectious diseases expert, warned that outbreaks in the South and West could engulf the country.
