Practice questions on Neisseria Meningitidis
A 6-year-old boy has meningitis. CSF culture grows Neisseria meningitidis serogroup B. What is recommended for household contacts?
- No prophylaxis is needed.
- Antibiotic prophylaxis with rifampin.
- Antibiotic prophylaxis with ciprofloxacin.
- Vaccination with MenACWY vaccine.
Answer: B. For close contacts of a case of meningococcal meningitis, antibiotic prophylaxis is recommended to reduce secondary cases. Rifampin is a common choice for prophylaxis against serogroup B strains, although ciprofloxacin may also be used depending on local guidelines. The MenACWY vaccine does not cover serogroup B.
