Researchers at Queen Mary Hospital, London, have revealed that Roche's Tamiflu, an anti flu drug, works against the bird flu virus H5N1 strain (the most lethal one). They say the drug is effective against avian and human forms of the virus.

In a study the researchers said that Tamiflu (oseltamivir) is effective against the strain that is now hitting Vietnam and Thailand.

Tamiflu is a neuraminidase inhibitor, it blocks the action of the viral enzymes.

The World Health Organization (WHO) has mentioned Tamiflu as the drug for tackling bird flu if ever a human pandemic breaks out.

Tamiflu has been used effectively in other strains of bird flu. In the Netherlands, in 2003, when 1,000 people were infected with the H7N7 strain, the drug proved to be very effective.

Tamiflu is currently used in Europe, USA and Japan for type A and B influenzas. It now seems that it is also effective against the bird (avian) flu virus H5N1 strain.

The WHO and many health experts around the world have warned of the risk of a massive outbreak of human to human bird flu. The WHO says Tamiflu could be the drug of choice for this pandemic (if it ever happens).

Pandemics hit the planet every 27 years. The last one hit about 36 years ago.
