Prospective, periodical sero-epidemiological surveillance on mumps was carried out in three different populations in Aichi prefecture. 1) In a newly developed residental quarter full of big apartment buildings, where heavy population density burst has been occurring, mumps has been observed as an endemic disease. Serologically, almost all the children under six years old has experienced mumps infection in such an area. 2) In an old city with stable population dynamics, mumps outbreaks have been taken place pediodically. The results of serosurvey suggested that the periodic outbreaks occurred when more than 60–70% of the children became susceptible, regardless of seasons. 3) In a relatively isolated small town, mumps epidemics has not been observed for many years and when the disease is introduced into the community however, large outbreak develops in the town. |
