[Investigation of measles, rubella and varicella IgG antibody levels among migrant and native pupils in Changning District of Shanghai].

OBJECTIVE

To define the measles, rubella and varicella immunoglobulin G (IgG) anti-body levels among migrant and native pupils so as to advise effective measures for measles control and prevention.

METHODS

241 pupils at four or five grade were recruited from 3 primary schools in Changning District. Measles, rubella and varicella IgG antibody levels were tested.

RESULTS

The positive rates of measles, rubella and varicella IgG antibodies of the 241 pupils were 96.68%, 79.67% and 57.68% respectively. The positive rates of IgG antibodies of meales and rubella were not significant difference between the migrant and native groups, but the concentrations of IgG antibodies of measles and rubella in migrant group were higher than those of native group. The positive rate of varicella IgG antibody in migrant group was also higher than that of native group.

CONCLUSION

There was a high potential to outbreak of varicella in primary schools. Surveillance and prevention for infectious diseases and health education should be reinforced in schools. The pupils who have no varicella history are recommended to administer varicella vaccine.
