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 newly 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 around 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.

But one day after the girl got home from a week of playing in the pool, worshipping with friends and bunking in a dormitory, Ford got an email about an outbreak and then learned that her daughterโ€™s camp buddy was infected.

โ€œIt was very nerve-wracking. It kind of seems like we finally felt comfortable and it happened,โ€ Ford said, adding that her daughter ultimately tested negative.

Ford said she definitely plans to get her daughter vaccinated but hadnโ€™t done so because there wasnโ€™t much time between the start of camp and the governmentโ€™s authorization of the Pfizer vaccine for 12- to 15-year-olds in May.

A note posted on the campโ€™s Facebook page showed that the camp nurse and several other staff members and volunteers were among those infected. Staff members at the camp did not return a call for comment.

JoAnn Martin, administrator of the public health agency in surrounding Pettis County, lamented the difficulty in getting people to take the virus seriously and get vaccinated.

โ€œIt has been a challenge since the first case,โ€ she said. โ€œYou have people who still say it is not real. You have people who say it is a cold. You have people who say what is the big deal. You have people who say it is all a government plot.โ€

Dr. William Schaffner, a Vanderbilt University infectious disease specialist, said he isnโ€™t surprised by the outbreaks as camps reopen this year after being closed last summer. He said he had his doubts that some camps โ€œthought through all the implications of camping during COVID.โ€

Ideally, he said, camps would require vaccinations for adults and for campers who are old enough, and would take other measures such as serving meals in shifts, putting fewer youngsters in the cabins and requiring anyone unvaccinated to wear masks indoors.

In the Houston area, health officials reported more than 130 youths and adults tested positive for the virus in cases connected to a church camp. The pastor of Clear Creek Community Church in League City said the outbreak happened in two waves, first at the camp and then when people returned home in late June.

โ€œIn some cases, entire families are sick,โ€ pastor Bruce Wesley said on the churchโ€™s Facebook page.

In Illinois, health officials said 85 teens and adults at a Christian youth camp in mid-June tested positive, including an unvaccinated young adult who was hospitalized, and some people from the camp attended a nearby conference, leading to 11 additional cases.

The Illinois Department of Public Health said all the campers were eligible for the vaccine, but only โ€œa handfulโ€ of campers and staff had received it. The camp didnโ€™t check peopleโ€™s vaccination status or require masks indoors, according to the department.

The health department in Leon County, Florida, which includes Tallahassee, tweeted this month that an increase in cases there also was tied in part to summer camp outbreaks.

And in Kansas, about 50 people have been infected in an outbreak linked to a church summer camp held last month not far from Wichita.

Elsewhere the situation is better. The roughly 225 overnight camps and thousands of day camps run by local YMCAs are mostly open this summer, though with slightly reduced capacity, said Paul McEntire, chief operating officer for YMCA of the USA.

McEntire said he is aware of a few cases of Y camps where people tested positive for the virus, but no instances of significant spread. He said many camps are taking precautions such as serving meals in shifts or outside and trying to keep youngsters in separate groups. Most are requiring masks indoors, but he acknowledged it can be a challenge.

โ€œTo be frank, there are some parents that didnโ€™t want to send their kids unless they were assured that masking was being used indoors,โ€ he said. โ€œThere were others that took the exact opposite viewpoint.โ€

Ahead of the school year, the Centers for Disease Control and Prevention updated its guidance last week to say vaccinated teachers and students donโ€™t need to wear masks inside and 3-foot distancing of desks is not necessary for the fully vaccinated.

Summer camp outbreaks โ€œcertainly could be a precursorโ€™โ€™ to what happens when youngsters return to classrooms in the fall, said Dr. Michelle Prickett, a pulmonary and critical care specialist at Northwestern Memorial Hospital in Chicago. The outcome will depend on vaccination rates and which virus variants are prevalent, she said.

โ€œWe just need to be vigilant,โ€™โ€™ Prickett said.

Schaffner said he thinks schools wonโ€™t face similar outbreaks because they tend to be more structured and disciplined than camps and because most got used to making adjustments over the past year and a half. But he said the best way to reduce the risk is to get most people vaccinated.

โ€œThere are many parts of the country that simply have not grasped this,โ€™โ€™ he said.

It could be several months before regulators make a decision on authorizing shots for children under 12. Studies on such youngsters are still going on.

Meanwhile, in Tennessee, the stateโ€™s top vaccination official was fired Monday after facing scrutiny from Republican state lawmakers over her departmentโ€™s outreach efforts to vaccinate teenagers against COVID-19. Dr. Michelle Fiscus told The Tennessean newspaper about her termination. A Health Department official said the agency would not comment.

The Department of Health instructed county-level employees recently to stop vaccination events aimed at teens and to halt any online outreach to them, The Tennessean previously reported, citing emails it obtained.

Ford, the teacher whose daughter narrowly escaped getting COVID-19 at a Missouri summer camp, is worried.

โ€œWith the uptick in cases, I am concerned that we wonโ€™t be able to go back to normal, and we will have to ask people to mask and stuff,โ€ she said, โ€œand I have a feeling that there is going to be a huge argument.โ€
