Meningococcal meningitis in northern Ghana: epidemiology and control measures

Hospitalized meningococcal meningitis patients in northeastern Ghana during 1972-1973 were studied to provide baseline information about case clustering and age-specific attack rates to guide meningitis control programs. In 1973, group A meningococci were prevalent and 7% of isolates were sulfadiazine-resistant. In contrast to the age distribution of meningococcal meningitis in North and South America, peak attack rates occurred in 10- to 14-year-old Ghanaians. A mass immunization campaign using group A polysaccharide vaccine in heavily populated areas of the Bawku and Nalgerigu districts is recommended.
