title: Epidemiological investigation of measles in sera of healthy people in Heilongjiang Province, China.
abstract: Serological samples of healthy people were collected to obtain the levels of measles antibodies in different groups of people in Heilongjiang Province, China. Using quantitative enzyme-linked immunosorbent assays to measure the antibody levels, we found the lowest antibody positive rate and the lowest geometric mean concentration values in healthy people aged 15-39. This group is the population at high risk for adult measles in Heilongjiang Province, and is the focus of measles elimination work. The new challenges for the eventual elimination of measles will be to address immunization strategies in this segment of the population in order to control the incidence.
