To describe an outbreak of serogroup B neisseria meningitidis
occurred in Trinidad during 1998.
Epidemiological survey was conducted following the identification of the fist case in El Socorroi Trinidat.
Thirteen other cases were detected with the majority found among the <5 age group which accounted for 42.9%, followed by the 45-64 age group with 14.3%. Mortality was 57.1%, highest among the <5 age group accounting for 50% followed by the 25-44 and 45-64 age groups with 25%, respectively. Two distinct clusters of N. meningitidis
cases were identified using GPS/GIS systems which graphically demonstrated the link between the two clusters.
The implications of these results are discussed with respect to surveillance systems.
