hey mate here is ur answer
Avian flu, or bird flu, refers to a group of diseases that result from infections with specific influenza viruses. These viruses infect birds and — rarely — spread among humans. One virus that causes bird flu is called H5N1.
The H5N1 virus can cause severe flu with a high mortality rate.
However, according to the Centers for Disease Control and Prevention (CDC), transmission among humans is rare.
So far, the virus has shown no signs of changing genetically to spread more efficiently among humans. However, due to the severity of the illness that the virus can cause, authorities continue to monitor for these genetic changes. H5N1 bird flu is fatal in 60% of cases.
The first outbreak of H5N1 avian flu in humans occurred in 1997 in Hong Kong. Overall, authorities have reported more than 700 instances of human H5N1 infection — in Africa, Asia, and Europe. Indonesia, Vietnam, and Egypt have had the highest numbers of cases.
Below, we investigate whether the H5N1 virus poses a global threat to health. We also describe the symptoms, causes, and treatments of H5N1 bird flu.
