[Mumps in Poland in 2006].

In 2006, 15,115 cases of mumps were reported in Poland. The incidence (39.6 per 100,000) was considerably lower compared to 2005 (188.5) and to the median incidence in 2000-2004 (104.6). The decrease of mumps incidence in 2006 is related to high coverage of routine two-dose immunisation against measles, mumps and rubella, maintained since its implementation in 2003. Children 5-9 year old were the most affected age group (incidence 328.7 per 100,000). Since the immunisation schedule during 2003-2006 involved administration of MMR doses at the ages of 2 and 10 years, a stable decrease of mumps incidence is expected after routine immunisation will cover the school age birth cohorts (6-14 year olds). Of 15,115 cases, 656 (4.3%) were hospitalized and no deaths attributed to mumps were reported.
