A 19-year-old is diagnosed with meningococcal meningitis. What should be offered to his close household contacts?
Answer and explanation
Correct answer: A. A single dose of ciprofloxacin as chemoprophylaxis
- Step 1: Close contacts carry a small but real risk of secondary invasive disease in the days after a case. Step 2. UK public health guidance advises chemoprophylaxis, typically ciprofloxacin, for close contacts, and the case is notified to the health protection team. Answer: A single dose of ciprofloxacin as chemoprophylaxis. Why not the others: Amoxicillin does not reliably clear nasopharyngeal carriage. Isolation is not the control measure. Close contacts are at increased risk, so doing nothing is wrong.
