Bird flu virus is now known to have evolved in two forms by Groshan Fabiola

What was only a supposition, now it is proven, that the bird flu virus has evolved in two strains that are distinct genetically speaking. This is not good news as it might cause even more deaths among humans and the researchers will have to work double for finding an effective vaccine against these two forms of bird flu virus.
Between the year 2003 and 2005, US scientists have been collecting and analyzing more than 300 samples of H5N1 virus taken from infected birds and humans. They discovered that in 2003 and 2004 the human and bird population was affected by the same type of virus that was active in Vietnam, Cambodia and Thailand. But in 2005 a new strain of H5N1 virus appeared and infected people from Indonesia. This virus is in a continuous genetic development and as time goes by our treatment option become more and more restrained.

Since 2003 the virus affected 180 people and killed 100 from all over the world. Doctors are afraid that a pandemic could start if the virus is not kept under control and hope that this virus will remain a bird virus and will not change into a human one. If the virus gains the ability of transmitting itself from human to human then the whole world population is in danger.
Fortunately, according to the scientists those two forms of the virus do not have the possibility of spreading easily from on person to another.

Until now the US scientists have been trying to find a vaccine that will kill both viruses. The vaccine will be 100% definitive once the exact form of a pandemic virus is known. The scientists believe that one vaccine could offer partial protection against the other type of virus strain if it works against the first one.

Scientists need to move fast because the viruses have the ability of changing their status and of developing very fast, gaining even the possibility of transmitting themselves from one person to another.

The thing is that no one had expected for the virus to travel around the world so easily and to mutate so fast creating another strain. But scientists are confident that by keeping the virus under control in birds they can find a suitable vaccine in a year or two. As long as the governments work together and help each other there is no need for panic as there is still hope for a cure.
