Daily COVID-19 case rates across the country have risen in nearly all states since June as the highly contagious delta variant spreads, according to a new report from USAFacts.
The report, which excludes Nebraska because the state no longer regularly updates COVID-19 case counts, found that every state but Iowa has increased daily new cases compared to mid-June.
USAFacts’ analysis also shows that six states have seen their number of positive COVID-19 cases shoot up more than 400% in recent weeks: Alabama, Arkansas, Louisiana, Mississippi, South Carolina and Tennessee.
All 15 states with a seven-day average case rate higher than the U.S. average, around 18 cases per 100,000 people, also had lower vaccination rates than the U.S. as a whole, although not all states with low vaccination rates have seen case rates spike.
Seven-day averages of COVID-19 cases per 100,000 people vary between Iowa’s low, with a rate of 1.5, to Louisiana’s high with more than 79.2 cases per 100,000 as of July 27.
While cases continue to increase, the seven-day nationwide average is still down from 250,527 in its peak in January to 58,192 cases, a 77% drop.
