Parvovirus B19 is most commonly spread via which route?

• A. Respiratory secretions
• B. Blood transfusion
• C. Contaminated water
• D. Sexual contact

Answer: (A)

Parvovirus B19 is spread mainly through respiratory secretions, meaning droplets from the nose or throat during coughing, sneezing, or close contact. This makes the respiratory droplet route the most common way the virus is transmitted, especially among children in close-contact settings like schools. Other routes, such as transmission through blood products or vertical transmission from mother to fetus, can occur but are less common. Contaminated water or sexual contact are not typical routes for this virus.
