Introduction: Despite of the decline in the incidence rate of mumps which is the main result of the modifications of the Polish Immunization Programme (the vaccination against mumps has become obligatory since 2003), it is still a disease which occurs frequently in children.
Objectives: The main objective of the present article was to analyze the epidemiological situation of mumps in Poland in 2010 in comparison with the data from previous year. This paper was based on aggregated data published in "Infectious diseases and poisonings in Poland in 2010", "Vaccinations in Poland in 2010", "Case definitions for the infectious diseases used for the surveillance purposes in 2009-2011" and Polish Immunization Programme for 2010.
Results: In Poland in 2010, 2 754 cases of mumps were reported. The incidence rate was 7.2 per 100 000 and was lower in comparison with the incidence rate observed in 2009 (7.7) and five times lower than the median incidence reported in 2004-2008. The highest incidence rate was observed in the children aged 5-9 years (53.9). Thirty two out of2 574 notified cases were hospitalized (1.16%).
Conclusions: Realization of the vaccination against mumps using conjugate MMR (measles-mumps-rubella) vaccine contributed to the decrease in the incidence rate of mumps in Polish population. The high vaccination coverage implies that the incidence rate of mumps will be still decreasing.
