After falling rapidly for two months, the rate of COVID infections in the United States has fallen since mid-June thanks to localized rises in the country’s poorly vaccinated regions, data showed Monday.

According to the covSpectrum tracker, the highly contagious Delta variant continues to gain strength and now accounts for 35.6% of cases sequenced in the last two weeks. Authorities have said it is about to become the dominant strain in the country soon.

The seven-day average of new daily cases has stood at around 11,500 since June 16, according to the Centers for Disease Control and Prevention, or about 3.5 per 100,000 people.

A clear division has emerged across the country, with cases increasing rapidly in communities with low vaccination rates.

For example, the city of Springfield, east of midwest Missouri, is experiencing an increase of 36.8 new cases per 100,000 and only has 35% of its population vaccinated with one or more doses, display a COVID ActNow control panel.

On the other hand, Burlington, in northeastern Vermont, sees only 0.9 new cases per 100,000 and has 71% of its population vaccinated with one or more doses.

Nationally, 54% of the 332 million people in the United States have received one or more doses, while 46.1% have had two doses, according to the CDC.

The national momentum for vaccination reached its peak in mid-April, but has since declined. much higher in Republican states than those who vote predominantly for Democrats.

Cases fell sharply across the country from mid-April to early June, a period that coincided with the spring weather and increased outdoor socialization.

The heat of summer, however, has caused more people inside, where respiratory disease mainly from the air is spreading mostly. Air conditioning contributes to drying out the air and making conditions more favorable for the virus to remain viable.

All of this poses a danger to unvaccinated people, who are more exposed than ever to the highly contagious Delta variant.

According to UK research, the Pfizer-BioNTech vaccine was 88% effective in protecting against symptomatic Delta diseases, but only 33% after a dose.
