Human risk on Avian Flu

H5N1 has caused a very large number of detected cases of severe disease and death in humans. The sacry part is that, it is possible that only the most severely diagnosed cases are reported, while milder cases go unreported. Therefore there is a need to control the spread of virus.

WHO recently reported evidence of human-to-human spread in Indonesia. In this situation, 8 people in one family were infected. This shows how contagious the infection can be. So far, there is no vaccine to protect humans against H5N1 virus.
