Best methods include having lots of water throughout day and avoiding contact to virus as:-

1.Avoid touching nose or mouth
2.Wash hands everytime before meal or touching nose/mouth
3.Do jal neti kriya or try cleaning your nose with salt water and cotton. This flushes out colonies of virus.
4.Try handwash instead of soap.
5.Avoid crowded areas
6.Wear masks if you are low on immunity
7.Have lots of vitamin C(Amla)


The vaccines will be available in Delhi and NCR by next month,i.e,by march.

Though injectable vaccines (Influvac, Agrippal, Vaxigrip, Vaxiflu-S and Fluarix) against swine flu are available, the Government has ruled out universal vaccination for now and has recommended that it be used only for people who are actively treating the swine flu patients (doctors and other medical practitioners).


If you have sudden fever for more than two days and breathlessness,contact your doctor.

Swine flu can only be diagnosed for sure in labs. It is diagnosed by identifying the particular antigens associated with the virus type. In general, this test is done in a specialized laboratory and is not done by many doctors’ offices or hospital laboratories. However, doctors’ offices are able to send specimens to specialized laboratories if necessary.


  • Drink alot of water(prevent dehydration) and stay warm(prevent chills) since this is one of the best options.
  • Paracetamol for fever and ibuprofen for pain(Combiflam for both) and other symptomatic treatment can be done.
  • There are certain antiviral drugs which help treat swine flu – Zanamivir (Relenza) and Oseltamivir (Tamiflu).One should take these only with a doctor’s prescription since indiscriminate use could lead to resistance to the virus.
  • The patient will need to be hospitalized, isolated and put on a ventilator in severe cases.
