Fifty summer camps nationwide have had to cancel sessions or send campers home early because of concerns about the swine flu.
To protect children from the swine flu, the Muscular Dystrophy Association in June canceled 47 camps that 2,500 campers were expected to attend.
The American Lung Association has also advised that its summer camps be closed. The Associated Press reported:
"The American Lung Association has advised its affiliated camps to close, including one in Colorado that was scheduled to begin next week. Champ Camp in Ward was a traditional sleep-away weeklong camp for boys and girls with asthma -- no campfires allowed.
"The decision came after four campers were hospitalized when they became sick at an affiliated camp in Julian, Calif., said Heather Grzelka, spokeswoman for the Washington-based Lung Association.
"Grzelka said the association has about 50 affiliated camps nationwide, but that they are not run by her group and that she wasn't sure how many would close."
