What is Bird flu(H5N1)?
- H5N1 is a type of influenza virus that causes a highly infectious, severe respiratory disease in birds called avian influenza (or “bird flu”).
- Human cases of H5N1 avian influenza occur occasionally, but it is difficult to transmit the infection from person to person. When people do become infected, the mortality rate is about 60%.
- Animal influenza viruses are distinct from human seasonal influenza viruses and do not easily transmit between humans.
- However, zoonotic influenza viruses – animal influenza viruses that may occasionally infect humans through direct or indirect contact – can cause disease in humans ranging from a mild illness to death.
- Host: Birds are the natural hosts for avian influenza viruses.
