WHO researchers say the H1N1 flu virus that swept the globe in 2009 has mutated, with the new strain appearing in Singapore and Australia.

The new virus has a genetic twist, making it resistant to drugs like Tamiflu and Relenza, the two mainstay drugs used to tackle the virus.

The World Health Organisation's influenza research group says more than 10 percent of H1N1 flu infection samples from Singapore, collected during the early months this year, showed mildly reduced sensitivity to the two drugs.

The H1N1 virus, commonly known as the swine flu, started to terrorize the world in 2009 and the fears have not gone away. It is still a health concern yet, there have been a ton of myths about the flu. Knowledge is power, especially when dealing with something as scary as a pandemic. Ignorance and fear can spread faster than a flu and can cause almost as much trouble.

Swine flu, or H1N1 as it is officially known as, seems to be with us as a health risk for the long run. Since H1N1 can be deadly, special precautions must be taken when dealing with it and special care is required for victims of H1N1. Linked is an excellent tutorial on caring for a patient with H1N1 Swine Flu. It is designed for the non-medically trained family caregiver of an H1N1 patient and provides a lot of good information on sanitation, preventing further transfer of the virus, and ways to minimize the effects of H1N1 and ensure a speedy recovery.
