The United States has surpassed 5 million COVID-19 cases. It took just six weeks for the number of Covid-19 infections to double in the U.S., which logged the last 1 million infections over the last two weeks, according to data compiled by Johns Hopkins University.

The latest grim record comes as growth in new cases in the U.S. appears to be leveling off at an average of 54,235 new infections a day over the last week. New cases peaked at 67,902 new cases on July 19, based on a 7-day average, after a resurgence of coronavirus cases ripped through the Sun Belt states in June and July.

California and Florida have both reported more than 500,000 total cases since the outbreak hit the U.S. in late January and Texas is closely approaching that number. Total cases for each state now exceed New York, which was once considered the epicenter of the nation’s outbreak earlier this year. However, those states have reported far fewer deaths than the Empire State, which has lost more than 32,000 people to the coronavirus so far, according to Hopkins.

Doctors say they’ve been able to save more lives compared with the peak in New York in March and April because they know more about the virus and have discovered better treatments, such as remdesivir. The recent surge in cases has also affected far more younger people, who also have higher survival rates.
