Can the existing avian influenza virus be transferred from one human host to another? Why or why not?
Rudiy27

Answer:

Hello, As long as the bird flu virus doesn't change into a human flu virus, it won't spread far in people. But sometimes after close personal contact a person who gets bird flu does infect another person. They can get the virus from tainted surfaces, such as cages and other farming equipment. Most people with the virus have had direct contact with infected poultry or objects contaminated with bird feces or secretions. Until now, very few cases of human-to-human transmission have occurred. Hope That Helps!
