People between the ages of 31 and 60 years accounted for two in three deaths, shows an analysis of 832 deaths for which data is available. Children under 12 years were the least affected in the current outbreak, accounting for 4% of overall swine flu deaths.
The swine flu outbreak devastated five states, with Rajasthan, Gujarat, Maharashtra, Madhya Pradesh and Telangana accounting for 78% of the total deaths till March 8.
Again, more than three in four infections (76%) were reported from five states: Rajasthan, Gujarat, Delhi, Maharashtra and Telangana.
Delhi has emerged as the best-performing state in controlling infection - while the state 3,658 cases, only 10 deaths have been reported from Delhi and the NCR.
Surveillance data shows that virus shows no gender bias and has affected an almost equal number of men and women: of the 832 deaths studied, 425 were men (51%) men and 407 (49%) women.
Swine flu spreads through droplets expelled when an infected person coughs or sneezes or by touching surfaces contaminated by the droplets. You can protect yourself by staying away from infected persons, frequently washing hands with soap, and cleaning surfaces with disinfectant or warm water regularly.
Symptoms include high fever, extreme breathlessness, lethargy, pain in the chest, loss of appetite and nausea or vomiting.
Three pharma companies in India - Hetero, Natco and Strides Acrolab - are manufacturing oseltamivir, the drug used to treat swine flu. Having the anti-viral prescription drug oseltamivir (better known by one of its brand names, Tamiflu) shortens the duration and severity of illness if the taken within 48 hours of the symptoms appearing. It also makes people less contagious and prevents them from infecting others. Oseltamivir also protects against other strains of influenza, such as influenza A (H3N2) virus, which accounted for 87.5% influenza A cases in the northern hemisphere.
