Shortly before the start of the third summer of the pandemic, the USA is undergoing a sixth wave of COVID-19 cases.
Compared with previous surges, this one looks more like a swell, health experts said.
The rise in cases reported in the Northeast in recent weeks appears to have peaked, but upward trends continue in at least 21 states, according to a USA TODAY analysis of Johns Hopkins University data. Health experts said cases are likely higher because of underreported home tests.
