Measles and mumps immunity in northern Greece, 2004-2007

Abstract

A cross-sectional study was conducted in order to determine the prevalence of mumps and measles antibodies in a representative sample of the general population in Northern Greece between January 2004 and May 2007. Overall, 900 healthy individuals participated in the study. The great majority were found to be protected against measles. The total protection rate against mumps was significantly less (87% versus 72%, respectively; p<0.01). Compared to all other age groups, statistically significantly lower protection rates were found in children younger than 1.5 years (p<0.01). The lowest rates of all adult groups were found in the age group of 21 to 30 years (86% and 68% for measles and mumps, accordingly). In conclusion, protection rates against both measles and mumps seem to be lower than expected in certain age groups, such as infants and young adults.
