Carriage Rates and Serogroups of<i>Neisseria meningitidis</i>among Freshmen in a University Dormitory in Korea

Abstract

The meningococcal carriage rate among first year university students who resided in a dormitory did not significantly increase over 4-week interval between cultures, which is markedly different from those reported in Western studies. Close social contact appeared to be related with carriage. Our data also revealed diversity in PorA types, suggesting the possibility of rapid mutation of the PorA gene during the 4-week interval.
