title: [Subacute sclerosing panencephalitis in Poland in the years 1990-1993. Stage V of epidemiologic studies].
abstract: The authors summarize the results of the fifth stage of epidemiological investigation on SSPE. The first stage covered the years 1971-1976, the next stages covered the periods: 1977-1983; 1984-1986; 1987-1989. In the period 1990-1993 data on 95 patients with SSPE were obtained. Morbidity rates continued to show a decreasing tendency (from 0.8 to 0.6 per 1,000,000 population) in the years 1990-1993, being lower the median morbidity (amounting to 0.98) in 1985-1989. Morbidity rates continued to shift towards older age groups: while the peak morbidity (25.7%) in the years 1990-1992 was noted in the 14-15 age range, in 1993 the peak (28.6%) was found in the age group of 16 to 19 years.
