Measles in Poland in 2019.

Introduction: Since 1998 Poland has endorsed measles elimination programme which is coordinated by the World Health Organization (WHO). To accomplish measles elimination in the country, achievement of vaccination coverage at 95% in the population is needed, as is the monitoring of the epidemiological situation, i.e.: reporting on cases suspected of measles and conducting laboratory diagnostics in WHO Reference Laboratory. Polish Reference Laboratory is located at the Department of Virology NIPH NIH - NRI.

Objectives: The aim of the article is to analyze the epidemiological situation of measles in Poland in 2019 with presenting the measles vaccination coverage and the progress of the measles elimination programme in Poland.

Material And Methods: The epidemiological situation of measles in Poland was analyzed on the basis of the case-based questionnaires of cases suspected of measles sent to NIPH NIH-NRI by the Sanitary and Epidemiological Stations, data from the publications: "Infectious diseases and poisonings in Poland in 2019" and "Vaccinations in Poland in 2019".

Results: In 2019, 1,502 cases of measles were notified to the surveillance system in Poland (incidence 3.91 per 100,000 population, more than four times more than in 2018). The highest incidence was observed in the aged 35-39 was estimated at 11.36 per 100,000 population. Out of all cases, 772 (51.4%) were hospitalized. No fatal cases due to the measles were reported. In 2019 the maintenance of high vaccination coverage among children aged 2 and 12 years old was observed - from 92.6% to 99.5% (primary vaccination, children born in 2009-2017).

Conclusions: The epidemiological situation of measles in 2019 in comparison with the situation in 2018, has deteriorated. This was a trend in throughout Europe.
