Question
Due to the increase in S. Enteritidis in Trinidad and Tobago, CAREC focused their analyses on
this serotype. The following data are for S. Enteritidis only.
From 1995-97, 227 laboratory-confirmed cases of S. Enteritidis infection were reported in
Trinidad and Tobago. Approximately, 76 cases were reported each year for an annual incidence
of 6 per 100,000 population. In general, the geographic distribution of patients with S. Enteritidis
infection reflected population distributions on the two islands. The largest numbers of cases were
reported from the most populous counties of St. George and Victoria.
A similar proportion of S. Enteritidis infections occurred among males (48%) and females (52%).
However, the distribution of cases varied by age group (Figure 4) and month of diagnosis (Figure
5).
