Two medical students have tested positive for swine flu in Himachal Pradesh, taking the toll in the Kangra district to three.
This comes after a woman was diagnosed with the deadly HINI virus earlier this week at Doctor Rajender Prasad Government Medical College (DRPGMC).
The two people who have fallen prey to the disease are students at DRPGMC and have been shifted to isolated wards for treatment.
Medical Superintendent of DRPGMC, Dinesh Sood, said masks have been distributed among students and staff members as a precautionary measure.
"We have reported three swine flu cases here and their treatment is going on. Health of these students who are under treatment is improving," said Sood.
Swine flu is caused by H1N1 virus. H1N1 symptoms are similar to those produced by other influenza viruses - fever, cough, sore throat, body aches and respiratory problems.
Symptoms for swine flu include high fever, headache, muscle pain, diarrhoea, vomiting, stomach pain and internal and external bleeding. It is transmitted to people primarily from ticks and livestock animals with an incubation period of up to nine days. Human-to-human transmission takes up to two weeks.
