Does a person who had an exposure to someone with meningococcal infection (MI) need chemoprophylaxis?

Antibiotic prophylaxis (chemoprophylaxis) is administered to prevent secondary cases of MI among susceptible people and to stop the spread of infection.
Chemoprophylaxis is administered to individuals who have been in close contact with MI as early as possible (no later than 7 days after the contact).
