Linda Robinson of Raleigh said the news of an H1N1 outbreak among campers at Duke University was a concern, but not enough to cancel her son's plans for lacrosse camp this week. The university announced Thursday that 14 students on campus for a variety of summer programs had been diagnosed with influenza and a dozen more were showing symptoms of flu.

Parents of sick campers have been asked to take them home, according to Michael Shoenfeld, the university's vice president for public affairs. He said parents of incoming campers have been alerted as well.

"We've advised parents of students who are coming into camps over the next couple of weeks that if your child is exhibiting any kind of flu-like symptoms, don't bring them to camp, we will refund your money," said Shoenfeld.

Between 1,000 and 2,000 middle and high school-age campers are on Duke's campus in any given week over the summer. Some stay for multiple camp sessions. The infected students were in the Duke Talent Identification Program (TIP), American Dance Festival, and summer science and writing programs.

Shoenfeld said the sick campers have been isolated in a residence hall until their parents arrive and are under the care of Duke doctors. No students have been hospitalized.

He added that the university developed protocols for dealing with H1N1 in the camp setting in the spring.

For Robinson, the news was another reminder for her teenage son to take precautions.

"All summer long, they're going to be exposed to people from other places," she said. "Even if it's just people from Raleigh at the swimming pool, it would be concerning. But rather than lock them indoors, they're going to have to learn to take care of themselves and really have to wash their hands and take other precautions."
