The mean age was 24 years with a range of 22-30 years. The epidemic peaked in the month of November to January. Fever with cough was the most common clinical manifestation. Most of the patients were hospitalized and treated with oseltamivir. All the positive patients, were advised home isolation for 5-7 days after discharge.
