Myths about Swine Flu
You can get swine flu from eating pork . WRONG! Despite the common name of the disease, eating pork products does not spread H1N1 influenza. The virus spreads through the droplets expelled in the air form infected people coughing and sneezing. People are contagious from one day before to seven days after developing the symptoms of Swine Flu
There is no cure for Swine Flu. WRONG!! Having the anti viral prescription drug OSELTAMIVIR (commonly sold under the brand name TAMIFLU or FLUVIR) shortens the duration and severity of illness if taken within 48 hrs of the symptoms appearing. It also makes you less contagious and prevents infection also. It also protects against other strains of influenza.
The swine flu virus has mutated:- Gene sequencing of H1N1 virus by India’s two premier labs- National Institute of Virology Pune and National Centre of Disease Control Delhi showed that the virus has not mutated
India has shortage of Drugs:- there is no shortage. The virus causes mild disease in most people and less than one percent people infected need drugs for treatment.
You can get Swine Flu only once in your life :- H1N1 virus works like other seasonal Flu Viruses and may re-infect you in the coming years. Since you can get it again and again if you are in frequent contact with the contagious people, all health workers treating people with Swine Flu should get vaccinated against it which offers one year protection against the virus.
