A 4 year old with close contact 10 days ago to a school classmate, now hospitalized with meningococcemia, currently has no symptoms and a normal physical exam. No other cases have been reported in the community. Appropriate management would include

• A. Oral rifampin prophylaxis
• B. Nasopharyngeal culture
• C. Reassurance
• D. Meningococcal vaccine

Answer: (C)

The main concept is postexposure chemoprophylaxis for meningococcal disease in close contacts. After exposure to a confirmed case, close contacts should receive antibiotic prophylaxis within about 14 days to eradicate nasopharyngeal carriage and prevent secondary illness, even if they are currently asymptomatic. In this scenario, the child had close contact with a meningococcal case 10 days ago and is asymptomatic. This is still within the window where prophylaxis is recommended, so giving an antibiotic prophylaxis (for example, rifampin, with alternatives like ceftriaxone or ciprofloxacin in appropriate situations) is indicated to reduce the risk of developing meningococcal disease. Why not reassure alone? Because close contacts are at elevated risk for developing the disease, and the purpose of prophylaxis is to prevent a potentially fatal infection, not just to observe. Nasopharyngeal culture isn’t the right move for immediate protection—it’s diagnostic and can take time, and a negative result doesn’t remove the need for prophylaxis in a known exposure. Meningococcal vaccination is important for longer-term protection, but it does not provide the rapid, targeted protection needed in the immediate postexposure period.
