Mumps in Poland in 2018.

INTRODUCTION

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.

AIM: To assess epidemiological situation of mumps in Poland in 2018, 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 2018" and "Vaccinations in Poland in 2018".

RESULTS

In total, there were 1 585 mumps cases registered in Poland in 2018. Incidence of mumps was 4.1 per 100,000 and it was lower in comparison with 2017. The highest incidence (6.6 per 100 000) was registered in Opolskie voivodeship and the lowest (2.6) - in Warmińsko-mazurskie voivodeship. The highest incidence rate was observed among children aged 5 years (39.2 per 100 000). Incidence in men (5.0 per 100 000) was higher than in women (3.4). In 2018, 28 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2018 was 92,9% and it was lower by 1.1% in comparison with year 2017.

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.
