Variety of avian influenza that Indonesian scientists found at the end of last year, is distributed to the ducks and has caused the deaths of hundreds of thousands of these animals in Indonesia. He is much more dangerous than the previous one. "Unlike chickens, ducks swimming in the river, but because the virus can spread for hundreds of miles," – says the chairman of the Centre for Research of the University of bird flu, "Erlang" Chayrul Nidom.
Also, scientists have warned that the death rate from the new H5N1 varieties as high as that of his former form. According to the latest WHO data, since 2003, 15 countries reported 610 cases of human infection with the virus H5N1, 360 of them to death. The most severe blow deadly disease caused by Indonesia: from 2005 infected 192 people, 160 of whom died. Outbreaks of avian influenza caused serious concerns virologists and physicians, they say the threat of a pandemic, similar to the scale of the pandemic, "Spanish flu" in 1918, which claimed millions of lives. However, while these viruses are not "learned" to spread traditional flu airborne and spread from person to person, there is no threat of a pandemic. These types of influenza so far could only catch people who are close contact with birds.
