The U.S. has seen a string of COVID-19 outbreaks tied to summer camps in recent weeks in places such as Texas, Illinois, Florida, Missouri and Kansas, in what some fear could be a preview of the upcoming school year.
In some cases the outbreaks have spread from the camp to the broader community.
The clusters have come as the number of confirmed cases of the coronavirus in the U.S. has reversed course, surging more than 60% over the past two weeks from an average of about 12,000 a day to about 19,500, according to data from Johns Hopkins University.
The rise in many places has been blamed on too many unvaccinated people and the highly contagious delta variant.
Gwen Ford, a 43-year-old science teacher from Adrian, Missouri, was cautiously optimistic when she eyed the dropping case numbers in the spring and signed up her 12-year-old daughter for the West Central Christian Service Camp in Missouri.
