ABSTRACT
1024 cases of hepatitis A were reported in 1999. The incidence rate was estimated to be 2.6 per 100,000. It represents 50% decrease compared to the preceding year. The incidence rates within rural and urban populations were similar. The highest incidence rates were reported in the NW and Central parts of the country. 31.9% of all reported cases occurred among children 10-14 and 5-9 years old. Evaluation of the efficacy of vaccination against HAV showed an incidence rate substantially lower in flooded area compared to the neighbouring one during the 1997 deluge. After the deluge epidemic of hepatitis A was not reported.

In Poland in 1999 rubella was characterized by an epidemiological stability. A total of 30 958 rubella cases (including one case of Congenital Rubella Syndrome) were registered. The incidence rate was 80.1 per 100,000 and was 28% lower than in 1998. Of all reported cases, children aged 14 and less accounted for 94.6% cases. The highest incidence rate was among children aged 7 years (752.8 per 100,000). Comparing with the eighties, the last decade was characterized by a decline of the mean incidence rate in the population under 30 years of age, which was probably the consequence of mandatory vaccinations of 13 year old schoolgirls. Also, a decline of incidence rate among 2-5-year old children was observed, which was probably due to recommended vaccinations with MMR-II vaccine. The incidence rate among children aged 6-9 years was higher in 1999, as compared with previous years. Of all rubella cases, 0.5% were hospitalized. No deaths from rubella were reported.

The strategies of World health Organisation for elimination of congenital rubella syndrome were presented. The ways of prevention of congenital rubella syndrome by appropriate immunization programs were discussed. The concomitant adverse effects and risks were presented. On the basis of epidemiology of rubella in Poland the authors propose the adjusted vaccination policy.

In 1998 in Poland the incidence rate of rubella has been reduced three times in comparison with 1997 outbreak. 43,239 rubella cases (111.8/100,000) were registered, including 4 CRS cases (1.0/100,000 live births). 148 persons (0.34% of all cases) were hospitalised. 94.1% of cases were children under age of 14. The highest incidence rate was noted in the group of age 5-9 (790.1/100,000). The following rate of vaccinated schoolgirls was reported in 1998: 97.3% in-group of 13-year old, 97.3%--14 y.o. and 98.9%--15 y.o.

2011 cases of hepatitis A were reported in 1998. The incidence rate was estimated to be 5.2 per 100,000; that represents almost 50% decrease compared to the preceding year. The incidence rates within rural and urban populations were similar. The highest incidence rates were reported in the NW and Central parts of the country. 19.6% of all reported cases occurred among children 10-14 years old. Evaluation of the efficacy of vaccination against HAV showed an incidence rate substantially lower in flooded area compared to the neighbouring one during the 1997 deluge. After the deluge epidemic of hepatitis A was not reported.

A cyclical epidemic of rubella has been noted in Poland in 1997. The relatively high incidence rate persistent in the last interepidemic period and local outbreaks in some areas in 1995-1996 caused smaller range of 1997 epidemic. The incidence was much lower than in 1986 and 1992 when the biggest registered rubella outbreaks were noted. The last epidemic outbreak of rubella didn't change significantly the existing relation between the incidence, age, gender and place of residence (rural, urban). The percentage of hospitalized cases was similar to past (0.2%).

Until 1997, hepatitis was registrated in Poland under the headings: hepatitis B and hepatitis non-B. In 1997, for the first time, the obligatory registration of hepatitis A cases was introduced. In the year 1997--4,045 cases of hepatitis A were notified in Poland. The incidence rate was 10.5 per 100,000 population with considerable differences in various voivodships. The incidence rate in rural areas was 2.5 higher than among urban population. The highest incidence rates were registered in the northern and north-eastern parts of the country. The 23% of reported cases occurred among children age 10-14.
