Each of the following would help prevent the spread of mumps EXCEPT:

  1. Notify the public only after confirming mumps exposure
  2. Stay home until cleared if infected
  3. Offer masks to patients and workers suspected of mumps
  4. Verify every patient and worker has the CDC-recommended mumps vaccine
Show answer and explanation

Correct answer: A. Notify the public only after confirming mumps exposure

  • A. Correct (the exception). Public health practice is to act proactively (isolate/notify contacts and implement precautions) rather than waiting until exposure is fully 'confirmed' before notifying — this delay would allow further spread.
  • B. Staying home while infectious directly reduces transmission, so this DOES help prevent spread.
  • C. Offering masks to suspected cases reduces droplet transmission, so this DOES help.
  • D. Verifying vaccination status helps identify susceptible individuals and prevent outbreaks, so this DOES help.
