( CNN ) -- Classes resumed last Thursday at the University of Kansas at Lawrence , and by Monday 47 students had swine flu , a college official said . The CDC recommends someone sick with the virus remain out of class for 24 hours after fever has abated on its own . Although that 's less than two-tenths of 1 percent of the 27,000-member student body , and no one has died or been hospitalized , the school has moved into action . `` The sanitizer 's out , '' said Todd Cohen , director of university relations . The university sent e-mails to faculty members asking them to create contingency plans so that sick students are not required to go to class , and to commuter students and their parents warning them that the students may have to be isolated if they fall ill. That same message has gone to students in dormitories . Arrangements are being made to isolate anyone who 's sick in their rooms by moving out their roommates and dropping off meals , Cohen said . None of the school 's cases of swine flu -- also called H1N1 -- has proven fatal or resulted in a hospitalization , he said , and none of the reported cases has been confirmed . Public health officials are simply assuming that anyone with flu symptoms has swine flu , because it 's the only form of the virus in circulation , he said . The school 's health center can do little for those who show up for help . `` They 're basically told to go home and rest and get better , '' Cohen said . Vaccines are unlikely to help much this year . Supplies are not expected until late October , and require some five weeks from the first inoculation -- two are required -- before they become effective . `` By then , it 's December and the semester is almost over , '' he said . So public health officials are focusing on more basic medical efforts . Students already overloaded with information at the start of the semester are being urged to sneeze into their sleeves , wash their hands frequently and stay home if they get sick , Cohen said . `` It really comes down to them taking personal action , '' he said . The Centers for Disease Control and Prevention recommends someone sick with the virus remain out of class for 24 hours after fever has abated on its own . Firm figures on just how many people have the illness are tough to come by . Doctors are not required to report it to state or federal health officials , said Maggie Thompson , a spokeswoman for the Kansas Department of Health and Environment . `` We 've stopped accepting tests from county health departments , '' she said . Instead , the department is focusing on a surveillance system that will test only those sites deemed representative . Otherwise , Thompson said , the state 's laboratories would become overwhelmed . `` There are just too many numbers . '' The state stopped counting laboratory-confirmed cases at 324 : `` But that is just a fraction of what we think is going on , '' she said . `` There could be as many as 10,000 cases in Kansas already . '' KU students are not the only ones catching swine flu , Thompson said : `` If you called any university of this size around the country it 's probably going to be about the same . '' At Auburn University in Alabama , 10 cases have been reported among the 24,000 students who started classes last Monday , a spokeswoman said . `` So far , everybody seems to be recovering , '' said Deedie Dowdle . The school 's emergency management team was meeting this week to decide how to handle larger-scale absences , she said . `` I 'm getting lots of reports of outbreaks in the Southeast Conference , '' said Dr. James Turner , president of the American College Health Association . `` I 'm anticipating several thousand cases among college students this fall . '' Among the preparations are plans for mass vaccinations , he said . But with school just beginning , much remains unknown , he said . `` We are just kind of hunkering down right now waiting to see where this goes . '' Turner is also executive director for student health at the University of Virginia , where classes are slated to begin Tuesday . `` We 're kind of bracing for what the week brings , '' he said . Turner said 63 students came down with swine flu during the summer session , and `` they all did fine . '' Last week , the CDC released tips for school administrators to follow . `` We 're hoping we 're on track to be ahead of this virus , to get the college-age population vaccinated once it becomes available in mid-October , and to keep students as safe and secure as possible , '' Health and Human Services Secretary Kathleen Sebelius told reporters in a conference call . Some U.S. colleges began reporting cases last April , after students returned from spring break . The University of Notre Dame in South Bend , Indiana , which reported one case of H1N1 last spring , is taking extra precautions ahead of the fall semester . `` We are attacking the disease , from each person taking the responsibility for good hygiene and healthy habits , '' said Ann Kleva , the university 's director of health services . The University of California has been stocking up on supplies for each of its 10 campuses over the past several months , university system officials said . Since mid-April , when swine flu was discovered , the CDC has tallied 522 deaths in the nation . `` We do know that H1N1 flu is circulating in the country right now , '' said Lisa Barrios , of the agency 's division of adolescent and school health . `` For the most part , it 's sporadic and regional . '' But she said the agency is not advising any schools to close . `` What we 're doing is keeping a very close eye on what 's happening with the flu during the fall and the winter , '' she said . The swine flu virus has captured the attention of public health experts because they worry it could mutate into a far more lethal form . `` If that does happen , then we may recommend that schools close , but right now we are not doing that , '' Barrios said . `` It 's important to balance the risks with the benefits of keeping kids in schools .
