An outbreak due to group-B meningococcus in a large Eskimo village stimulated an epidemiologic study of such an occurrence in an isolated community. All verified cases developed during a three-week period. Throat-culture surveys revealed that nearly 50% of a sample population harbored meningococcus during a nine-week period after the development of the last case. This finding was interpreted as showing that, in a fixed population, the actual development of meningococcal disease is related to factors in the exposed persons rather than to the conditions of exposure.
