Outbreaks of Streptococcus pneumoniaecarriage in day care cohorts in Finland – implications for elimination of transmission

Table 1 Numbers of episodes of pneumococcal carriage in the three day care cohorts for day care attendees and for all participants.

Clustering of carriage is most evident for serotypes 9V, 18C, and 19A, each being the dominant type in one DCC and not detected in the two other DCCs. Serotype specific episodes of pneumococcal carriage were constructed from the observed data by combining consecutive samples of the same serotype into episodes.
