Background:
Vaccination against mumps, introduced initially as recommended, from 2003 is mandatory in Poland and given as two dose scheme with MMR vaccine (mumps, measles, and rubella). Despite observed decline in mumps incidence for over a decade which is a result of conducted vaccinations, mumps is still a common childhood disease in Poland.
Aim:
To assess epidemiological situation of mumps in Poland in 2012, 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 2012" and "Vaccinations in Poland in 2012" (Czarkowski MP i in., Warszawa 2013, NIZP-PZH i GIS). 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 2012 was also used.
Results:
In total, there were 2779 mumps cases registered in Poland in 2012. Incidence of mumps was 7.2 per 100 000 and it was higher by 7.5% in comparison with 2011 and lower by 19.4% in comparison to median for the years 2006-2010. The highest incidence rate was observed among children aged 5 years (71.8 per 100 000). Incidence in women (5.9) was lower than in men (8.6). In 2012, 25 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2012 was 97.9%.
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
Mumps vaccination in Poland significantly reduced cases, with 2012 incidence lower than the 2006-2010 median. High vaccination coverage (97.9%) is expected to further decrease mumps cases.
Area of Science:
- Epidemiology
- Immunization
- Public Health
Background:
- Mumps vaccination, part of the MMR vaccine, has been mandatory in Poland since 2003.
- Despite a decade-long decline due to vaccinations, mumps remains a common childhood illness in Poland.
Purpose of the Study:
- To evaluate the 2012 epidemiological situation of mumps in Poland.
- To assess vaccination coverage within the Polish population.
- To compare 2012 data with previous years' trends.
Main Methods:
- Descriptive analysis using mandatory surveillance data from "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012".
- Mumps case classification followed European Union surveillance criteria.
- Data analysis incorporated the National Immunisation Programme for 2012.
Main Results:
- Poland registered 2779 mumps cases in 2012, with an incidence of 7.2 per 100,000 population.
- Incidence was 7.5% higher than in 2011 but 19.4% lower than the 2006-2010 median.
- The highest incidence occurred in 5-year-olds (71.8 per 100,000); 25 hospitalizations were recorded. Vaccination coverage for 3-year-olds reached 97.9%.
Conclusions:
- Systematic mumps vaccination, following the National Immunisation Programme, has led to a substantial reduction in reported cases.
- High vaccination coverage is anticipated to result in a continued decrease in mumps incidence.
