Drug-resistant XXXX in day-care centres in Stockholm County.

@entity1 @entity114 @entity328 @entity1576
Between January 1994 and July 1995, 40 pre-school @entity1 were found to have drug-resistant @entity328 (DRSP), i.e. reduced sensitivity to @entity114 (minimum inhibitory concentration, MIC, > or =0.1) and resistance to at least two other antibiotic drugs. Twenty-five of the @entity1 were index cases with symptoms of @entity1576 , and 15 @entity1 were carriers discovered in contact-tracing in connection with an index case. @entity1 attending the same group in the day-care centre as an index @entity1 were routinely screened. Thirteen of the index @entity1 were attending day-care centres. In 11 of these day-care centres, contact-tracing and nasopharyngeal swabs from 424 @entity1 and 128 day-care personnel identified an additional 13 asymptomatic @entity1 who were carriers of DRSP. In all but one case, the same serotype as the index case was discovered. No day-care personnel were carriers of the DRSP strain. Sixteen (64%) of the 25 @entity1 with symptoms caused by DRSP were 1 year old or younger, whereas eight (61%) of the 13 @entity1 who were carriers of DRSP were 3-4 years old. In conclusion, when a @entity1 attending a day-care centre is discovered to have @entity1576 caused by DRSP, there is a great probability that additional @entity1 will be identified in the group with the same DRSP strain.
