Surveillance on immunity to Mumps virus in population around Bangkok in 1995 was obtained from serum sample which were randomly taken from 240 normal people under ages ranging from a newborn to above 40 years. Results showed that 52.5 percent of the collected samples had an immunity to Mumps virus. Antibody to Mumps virus were found in the aged group of 0-8 months, 9-11 months, 1-4 years, 5-9 years, 10-19 years, 20-29 years, 30-39 years and 40 years or above at 33.3 ,0, 3.3, 53.3 ,76.7, 93.3 ,80 and 80 percent respectively. As calculated by sex, the rate of antibody presence were found 42.6 and 62.7 percent in male and female serum, respectively. These finding suggest that the 9-11 months, children group has the greatest risk of being infected by Mumps virus. In addition, there is a tendency that men would have the Mumps virus infected risk greater than women.
