lineages. What are those? (2) Correct Answer-B/Yamagata & B/Victoria
Determine the type of Influenza Virus described:
most stable with low pathogenicity (subclinical infection) Correct
Answer-Influenza C
Determine the type of Influenza Virus described:
is the least stable with antigenic drift & antigenic shift of the H and N
antigens producing new strains responsible for epidemics Correct
Answer-Influenza A
