RESUMEN
An outbreak of mumps occurred in the Mid-Ulster area of Northern Ireland between 1st November 1999 and 31st August 2000, with 729 cases notified. Salivary test results were obtained for 430 (59%) reported cases, of which 332 (77%) were positive for mumps IgM antibody. Three hundred and sixteen (95.2%) of these confirmed cases were in the age range 9 to 19. One hundred and eighty-four (55.4%) confirmed cases had received one dose of MMR (measles, mumps and rubella) vaccine, but only 3 (0.9%) confirmed cases had received 2 doses of MMR. The low incidence of mumps among children who had received two doses of MMR illustrates the importance of the second dose of MMR for full protection.

Between 19 February and 18 April 1987, 33 confirmed cases of puerperal fever caused by Streptococcus equisimilis serotype T204 occurred at three hospitals in and around Chelmsford. Most of the cases (70%) occurred on one ward, in which toilet seats and a shower are believed to have aided transmission, although insufficient data were obtained to exclude a role for person-to-person spread. Possession of M-protein antigen was demonstrated in the outbreak strain.
