As of right now, there is only one confirmed cases of H1N1 flu and two suspected cases at the school in Radnor. But any student who shows symptoms was being asked to stay home.
The school on Matson Ford Road was open as usual on Wednesday.
However, classes are cancelled the rest of the week. School officials said that move was not a requirement, but said they would rather err on the side of caution.
Practices and games are being postponed until further notice.
School administrators are urging everyone to wash their hands frequently and common areas are being disinfected throughout the day.
Some students could be seen wearing masks. Those were not required, but some felt better wearing one.
With this scare, some students said they planned on getting the swine flu vaccine as soon as it was available.
"I've had the flu before and it's really bad, you know? It's no fun," said senior Conner Day.
Officials say it could take one to two weeks to get enough vaccine in our area for those who want it.
As for other schools, parents are reminded to keep students home if they're sick.
