[Measles in Poland in 2003].
In Poland 48 measles cases were registered in 2003 (0.13 per 100,000 population)--of which 65% were cases imported from Chechnya and Afghanistan. Measles outbreaks occurred in 3 centers for immigrants. In total, 31 cases were reported, of which 96.8% were unvaccinated, and 93.5% were under 15 years of age. Of 17 local cases, 5 (29.4%) cases occurred in unvaccinated persons, 3 (17.6%) in persons vaccinated with one dose and 7 (41.2%) in those vaccinated with two doses of measles vaccine (administered at the age of 13-15 months and 7 years). Among 12 vaccinated cases only one 2-year old child was recently vaccinated. The remaining cases were in the 3-7 and 10-24 age ranges. The most affected were infants (incidence 0.57 per 100,000), 1-year old (0.28) and 2-year old children (incidence 0.27). Cases among adolescents and adults over 15 years of age increased from 23.5% in 2002 to 47.1% in 2003. The increasing age of locally-acquired cases, together with constantly high immunization coverage indicates high effectiveness of vaccinations in Poland. Out of all reported cases 13 (38%) were hospitalized. There were no deaths due to measles in Poland in 2003. Poland participates in the WHO Measles Elimination Strategy. Presently, the most important is the maintenance of a sensitive and timely surveillance of measles and measles-compatible cases, with serologic confirmation of one rash-like illness per 100 000 population. The performance of the surveillance system is insufficient with only 55 measles-compatible cases reported in 2003 (15% of expected reports). Serologic confirmation of cases was also insufficient, with 22 cases (40.0%) confirmed by IgM ELISA test. These results indicate the need to maintain the high immunisation coverage and improve measles surveillance system.
