[Measles in Poland in 1999]

As it is typical for the year after epidemic, in 1999, the number of new cases of measles decreased and incidence was 0.3 per 100,000. No cases of measles were reported in five out of 16 newly formed voivodeships. The highest incidence was in voivodeships dolnoślaskie and małopolskie (0.5 per 100,000). Regarding age groups it was highest among 5 years old--2.3 per 100,000 and among 13-24 months old--2.0 per 100,000. Cases of older children reflect delay in vaccination. For another consecutive year the fraction of cases confirmed serologically (assay for IgM) was insufficient (15.2%) and it requires further improvement.
