Influenza exhibits antigenic drift which involves _____.

Question

Quizplus · Accepted Answer

Influenza undergoes antigenic drift which involves mutations in the genes for hemagglutinin and neuraminidase. These mutations result in minor changes in the virus's surface proteins, allowing the virus to evade host immunity and causing flu epidemics. Gene reassortment due to multiple viral infections is a mechanism for antigenic shift, not antigenic drift. Mutations in envelope phospholipids and capsid proteins are not specifically associated with influenza's antigenic drift.
