RESUMO
Objective To investigate epidemiological characteristics of measles cases and the influencing factors of transmission of measles among floating children in Shenzhen. Methods Descriptive study was conducted in data which were collected from the report system of statutory infectious diseases from 2016 to 2018 in Shenzhen. Case-control study was conducted between 89 cases and relative controls. Results A total of 108 measles cases in floating children were reported from 2016 to 2018, and the incidence trend showed a year-on-year decline( 2trend=68.35, P<0.001). Analysis showed that nosocomial exposure in 7 to 21 days ago(OR=7.80, 95% CI:3.51-17.35, P<0.001), having been to the crowded places(OR=3.37, 95% CI:1.52-7.47, P=0.002), having contact history of fever-rash patients(OR=4.57, 95% CI:1.41-14.84, P=0.007) were influencing factors of transmission of measles among floating children, and immunization at the prescribed time(OR=0.12, 95% CI:0.04-0.32, P<0.001) was a protective factor for measles. Conclusions Vaccination must be strengthened for floating children. Medical institutions should avoid becoming a key place for measles transmission, and need to strengthen health education.
