Mumps in Poland in 2015
1National Institute of Public Health – National Institute of Hygiene in Warsaw, Department of Epidemiology
Background:
Vaccination against mumps from 2003 is mandatory in Poland and given as two dose scheme with MMR vaccine (mumps, measles, and rubella). Earlier this vaccination was only recommended. Despite observed decline in mumps incidence for over a decade which is a result of conducted vaccinations, mumps is still a common disease among the children (1-3).
Aim:
To assess epidemiological situation of mumps in Poland in 2015, including vaccination coverage in Polish population, in comparison to previous years.
Methods:
The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins “Infectious diseases and poisonings in Poland in 2015” and “Vaccinations in Poland in 2015” (4;5). Mumps cases were classified according to the criteria of surveillance case definition implemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC). National Immunisation Programme for year 2015 was also used (6).
Results:
In total, there were 2 208 mumps cases registered in Poland in 2015. Incidence of mumps was 5.7 per 100,000 and it was lower by 12,3% in comparison with 2014 and lower by 20.4% in comparison with median for the years 2009-2014. The highest incidence (9.1 per 100 000) was registered in Kujawsko-pomorskie and the lowest (3.3) – in Podkarpackie voivodeship. The highest incidence rate was observed among children aged 5 years (48.3 per 100 000). Incidence in men (7.1 per 100 000) was higher than in women (4.4). In 2015, 12 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2015 was 96,3% and it was lower by 0.7% in comparison with year 2014.
Conclusions:
Systematic execution of mumps vaccination in accordance with the National Immunisation Programme resulted in a significant decrease in the number of registered cases. Due to the high vaccination coverage further decline in the number of cases is expected.
Insights
Mandatory mumps vaccination in Poland significantly reduced cases by 20.4% since 2009. High vaccination coverage, reaching 96.3% in 3-year-olds, is expected to further decrease mumps incidence.
Area of Science:
- Epidemiology
- Immunization
- Public Health
Background:
- Mumps vaccination became mandatory in Poland in 2003, utilizing a two-dose MMR vaccine schedule.
- Despite a decade-long decline in mumps incidence due to vaccinations, the disease remains prevalent among children.
Purpose of the Study:
- To evaluate the epidemiological status of mumps in Poland during 2015.
- To assess mumps vaccination coverage within the Polish population and compare it with previous years.
Main Methods:
- Descriptive analysis utilizing data from Poland's mandatory surveillance system and annual bulletins on infectious diseases and vaccinations.
- Mumps case classification followed European Union surveillance criteria.
- Data from the National Immunisation Programme for 2015 were also incorporated.
Main Results:
- Poland registered 2,208 mumps cases in 2015, with an incidence of 5.7 per 100,000 population, a decrease from 2014 and the 2009-2014 median.
- The highest incidence was observed in 5-year-old children (48.3 per 100,000), with higher rates in men than women.
- Vaccination coverage for 3-year-olds in 2015 was 96.3%, a slight decrease from the previous year.
Conclusions:
- Consistent implementation of the National Immunisation Programme has led to a substantial reduction in registered mumps cases.
- High vaccination coverage is anticipated to result in a continued decrease in mumps incidence.
