So far the cases are considered to be mild. Because of that, students say it's time for everyone to relax.
"I guess I'm not that concerned. I feel like they've taken a lot of precautions to protect us," said junior Kristin Berry.
"There's not a lot we can really do about it while we're here. I think they're doing a pretty good job of taking care of it," said freshman Ian Campbell.
State officials say the four students who have been confirmed continue to recover from the mild flu symptoms after having been provided ant-viral medications and recovery instructions earlier in the week.
With that determination, school officials and the state decided to keep the campus open.
Students are urged to wash their hands and isolate themselves if they're ill.
So far, some 400 students have gone to campus health clinics, many of them with symptoms.
On Friday morning the Delaware Division of Public Health clinic began dispensing preventive doses to UD students who meet special health criteria and have had close contact with ill students.
The Health Division says examples include of students who mee the special criteria includ students who have chronic conditions such as chronic lung, heart, liver, blood, neurologic, neuromuscular or metabolic disorders; or are pregnant or are immunosuppressed; and the student must have been exposed to the flu through close contact with sick students, such as being in the same household, being a roommate, or being an intimate partner.
The vast majority of UD students will not need to be treated with preventive medication.
Any UD student who is experiencing flu-like symptoms is asked to go to Student Health Services in Laurel Hall, which is open 24 hours a day.
More than 30 public evens have been cancelled on the campus, including the University of Delaware Track and Field Open this weekend.
With confirmation from CDC Thursday that swine flu is present in the community, routine testing of UD students is no longer required and all flu-like symptoms will be treated as potential swine flu, officials said.
The DPH toll-free Swine Flu Call Center phone line continues to operate Monday - Friday 9 a.m. until 5:30 p.m. at 1-866-408-1899 for questions from Delaware residents.
