Health Minister Datuk Seri Liow Tiong Lai said they have been isolated and their progress monitored.
"We found that out of the 109 trainees at the centre, 52 were suffering from mild cough and fever but they do not have H1N1.
"There is no outbreak, it is just within this particular group and I ensure that action was taken so that no outbreak occurs," Liow told reporters after officiating a Skipping For Health function here.
Liow urged people to be wary of their health and cleanliness to avoid contracting the deadly virus.
"H1N1 is always in the country. Please wash your hands and if you have cough or fever, don't mix with others and wear a mask," he said.
He added that Malaysians planning to travel to cold countries should get vaccinated as the weather could make them vulnerable to diseases.
