NORMAL - With 20,000 students on its campus daily - and 6,800 of those living on campus - Illinois State University leaders are closely watching the swine flu's developments.

"There's a lot of information out there, but we're still in the early phase," of determining whether this will develop into a major concern or not, said Dr. Glenn Weiss, Student Health Services medical director.

Other area campuses report similar wait-and-see approaches.

In the meantime, Weiss' staff is revisiting ISU's pandemic response plan, and assessing inventory of items such as masks for students who might become infected, and for medical staff working with students. The plan last was revamped in 2006.

Weiss also is keeping in close contact with the McLean County Health Department and the Illinois Department of Public Health, to heed any of their advisories.

The university hasn't sent any organized groups to Mexico this semester, said Jimmy Brazelton, ISU's study abroad coordinator. Also, among ISU's international students, there currently aren't any Mexican students enrolled this spring in Normal, he said.

Illinois Wesleyan University and Eureka College also haven't sent any groups to Mexico recently. And neither have plans to do so this summer.

Lincoln Christian College and Seminary had planned to send about a dozen students on a mission trip to Mexico earlier this month. However, they changed plans in response to travel advisories about the drug cartel violence there, said Ed Plumier, who oversees such trips for the college. Instead that group stayed in the United States, for a trip to Georgia.

ISU still plans to send 26 students to its two summer programs in the Latin American nation - one to Taxco and the other Cuernavaca. Groups are set to leave May 16 and June 4.

"The plan is still in place for them to go," said Brazelton. He said he receives e-mail updates from the Centers for Disease Control, the Department of Homeland Security and an international educators' group as well.

None of those organizations have sent out travel alerts about Mexico, he said.

As for random groups of ISU students who may have traveled to Mexican spots for spring break, Dr. Weiss said the time period of concern has passed.

"Our break was mid-March. That's long-enough ago that we don't necessarily have to worry about that," he said.

Although, Alcapulco and Cancun are popular spring break spots for college students, all of central Illinois' area campuses had spring breaks fell during March, long before the April 13 early outbreak of swine flu in Mexico.
