Fifth disease contagious route?

Fifth disease contagious route?

• A. Blood
• B. Respiratory
• C. Fecal-oral
• D. Direct contact with vesicles

Answer: (B)

Fifth disease is caused by parvovirus B19 and is mainly spread through respiratory secretions. Droplets from coughing or sneezing, or contact with saliva and nasal secretions, transmit the virus from person to person. This respiratory route explains why outbreaks occur in places with close contact, like schools, especially in the colder months. The other options don’t fit the typical spread of this disease. It isn’t primarily transmitted through blood in everyday transmission (though parvovirus can be spread via contaminated blood products in rare cases), nor through fecal-oral routes. Direct contact with vesicles isn’t a feature of fifth disease—the rash is not vesicular, and transmission isn’t via vesicle contact as it might be with diseases like varicella or herpes.
