[Mumps in Poland in 1999].

In 1999, 90,214 cases of mumps were reported. Incidence of 233.4 per 100,000 was two and a half times lower than in the previous year. More then five percent (5.8%) of cases were admitted to hospitals (5,188). The percentage of hospitalised children ranged from 2.6% in ślaskie voivodeship to 9.9% in pomorskie voivodeship. Children in the 5 to 9 age group were mostly affected (incidence ranged from 1,581 to 2,295 per 100,000). Patients in this age group constituted 55% of total number of mumps cases. MMR vaccine is still not included into the national programme of immunization; instead monovalent measles vaccine is recommended and MMR vaccine is used on voluntary basis.
