Microbiology · Virology: adenovirus

Sample item

Several children at a summer camp develop fever, sore throat and unilateral conjunctivitis after swimming in a shared pool. Which virus is most likely?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Adenovirus

Adenoviruses are non-enveloped double-stranded DNA viruses that cause pharyngoconjunctival fever, linked with swimming pools and serotypes 3 and 7. They also cause epidemic keratoconjunctivitis, acute respiratory disease in recruits, and haemorrhagic cystitis in the immunosuppressed. They resist many disinfectants.

Option by option

  • A. Coxsackievirus A16

    Coxsackievirus A16 causes hand, foot and mouth disease.

  • B. Influenza A virus

    Influenza causes systemic illness with cough rather than conjunctivitis.

  • C. Enterovirus 70

    Enterovirus 70 causes acute haemorrhagic conjunctivitis without pharyngitis.

  • D. Adenovirus (correct)

    Correct. Pharyngitis with conjunctivitis after pool exposure is typical of adenovirus.
