Question

To cause a human pandemic, the H5N1 avian flu virus would have to

a. spread to primates such as chimpanzees.
b. develop into a virus with a different host range.
c. become capable of human-to-human transmission.
d. become much more pathogenic.

Answer 1

c. become capable of human-to-human transmission.

Step-by-step explanation:

• The H5N1 flu virus is a virus that is capable of causing infectious respiratory disease in birds and hence, it is an avian influenza virus and the infection caused by it famously known as bird flu.
• When it comes to humans, the humans may acquire the infection from consuming or being in close contact with infected birds however, the incidences of the human pandemic are rare.
• The reason for fewer chances of a human pandemic is because for such a pandemic to occur person to person spread is needed which does not happen in case of bird flu.
