Not sure if this ws already discussed here.....also not sure if this is NBME!
A two-month-old infant is admitted to the pediatric intensive care unit with severe pneumonia. The baby was delivered at 34 weeks gestation, but no other significant medical history is known. Sampling of the respiratory epithelium and subsequent culture reveal multinucleated giant cells. Aerosolized ribavirin therapy is initiated. Which is the following is correct about this infection?
A. Antibodies to hemagglutinin neutralize this virus.
B. Hospital outbreaks are impossible to contain.
C. IgM antibody is protective.
D. Outbreaks occur every five to seven years.
E. The virus may be isolated from the blood.
F. The virus presents as the ‘common cold’ in adults

i would choose either A or E.
RSV is a dis of children
it occurs yearly in the winter mont.
it is found in the secretions of the nose
IgA is the one to protect and not M
hospital outbreaks can be prevented by washing hands etc
i know the diagnosis is from culturing organism from secretions but confirmation is from ELISA. so i dont know the virus can be isolated from blood. so i will lean more towards A cos neutralising antibodies can be used in treatment of severe forms.
