Seasonal Influenza (H1N1) is a self-limiting viral, air-borne disease spread from person-to-person, through large droplets generated through coughing and sneezing, indirect contact by touching a contaminated object or surface (fomite transmission like telephone, cell phones, computers, door handles etc) and close contact (including hand shaking, hugging, kissing), the advisory said.

The symptoms are fever, cough, sore throat, runny or stuffy nose, difficulty in breathing.

Other symptoms may include body ache, headache, fatigue, chills, diarrhoea and vomiting and blood-stained sputum.

There are three categories of H1N1 influenza -- A, B and C.

After holding a state-level review meeting on H1N1, the Delhi government recently said all government hospitals in the city are equipped with necessary logistics required for the management of the disease and drug oseltamivir along with personal protective equipment (PPE kits) and N95 masks are also available.

The advisory also asked people to avoid crowded places in the swine flu season and stay more than an arm's length distance away from persons sick with flu.
