Influenza Virus Targets

Question

Influenza virus targets
A) respiratory epithelium.
B) gastrointestinal cells.
C) oral cavity cells.
D) throat epithelium.

Accepted Answer

Influenza virus primarily targets respiratory epithelium, especially in the upper respiratory tract, which includes the nasal passage, pharynx, and larynx. The virus attaches to the receptors on the surface of these cells and enters inside, causing infection in the respiratory tract. It can lead to symptoms such as cough, runny nose, sore throat, and fever. It does not target gastrointestinal cells, oral cavity cells, or throat epithelium specifically.
