“…1,32,33 In this study, we found a substantial reduction in the number of measles cases over a ten-year period in Tianjin, China, following implementation of two municipality-wide SIAs. There was a dramatic reduction in the incidence of disease in non-locals, whereas incidence stayed more stable in locals.…”

“…There was a dramatic reduction in the incidence of disease in non-locals, whereas incidence stayed more stable in locals. SIAs have been shown to be key in eliminating measles in the Americas, 1 and reducing the incidence of disease in Eastern Europe. 32 A study of 15 province-wide SIAs in China during 2004-2008 found that there was on average an 88.1% decrease in measles incidence the year after an SIA compared to the average rate in the preceding five years.…”

“…Measles was officially eliminated in the Americas in 2002, 1 and the other five regions of the World Health Organization (WHO) are slated for measles elimination by 2020. 2 This remarkable public health success in control of a highly infectious disease has been made possible through the universal recommendation for measles vaccination.…”

Summary Objectives China has repeatedly used supplemental immunization activities (SIAs) to work towards measles elimination, but it is unknown if the SIAs are reaching non-locals, migrants from rural to urban areas. This study characterizes temporal trends in measles incidence by local and non-local residency and evaluates the impact of SIAs on measles incidence in Tianjin, China. Methods Daily measles case counts were tabulated separately by residency. These two datasets were combined so that each day had two observations. We conducted Poisson regression using generalized estimating equations with an exchangeable working correlation structure to estimate rate ratios (RRs). Results There were 12,465 measles cases in Tianjin over the 10-year period. The rate of measles was higher in non-locals than locals before the 2008 SIA (RR: 3.60, 95% CI: 3.27, 3.96), but this attenuates to a RR of 1.22 between the 2008 and 2010 SIAs (95% CI: 1.02, 1.45). Following the 2010 SIA, non-locals had a lower rate of measles (RR: 0.78, 95% CI: 0.69, 0.87). Conclusions The disparity in measles incidence between locals and non-locals was reduced following two SIAs. Sustained public health interventions will be needed to maintain low measles incidence among non-locals given ongoing migration of people throughout China.

“…The widespread use of measles vaccines for over 30 y, as well as the implementation of measles control programs, has led to a substantial decline in global measles morbidity and mortality, and many countries have now moved from a control to an elimination phase. 1 Measles elimination is defined as the absence of endemic measles transmission in a defined geographical area for >12 months in the presence of a well-performing surveillance system.…”

A delay in the first dose of measles-containing vaccine (MCV1) may contribute to outbreaks of measles, resulting in a high age-specific incidence in infants<1 y of age. To determine the factors associated with delayed MCV1 vaccinations, we used data from the China Information Management System for Immunization Programming. Additionally, the parents/guardians of 430 children whose MCV1 vaccinations were delayed, as well as the parents/guardians of 424 children who received timely vaccinations, were surveyed by telephone. Children were less likely to receive timely MCV1 vaccinations if they belonged to an immigrant group, were male, had poor health status, had a father whose occupation e.g., a manager, had a history of delays in other Expanded Programs on Immunization (EPI) vaccinations, had parents who did not believe vaccinations were important for their children, and experienced shorter travel times to and longer waiting times in EPI clinics. The children of mothers whose occupational status (technician) were more likely to receive timely MCV1 vaccinations. The timeliness of MCV1 vaccinations should be considered as an additional indicator of the quality of vaccination programs.

“…Même si on a réussi à interrompre la transmission du virus de la rougeole endémique dans la Région des Amériques en 2002 (6), la transmission endémique subsiste dans cinq autres régions de l'Organisation mondiale de la Santé (OMS), soit l'Afrique, la Méditerranée orientale, l'Europe, l'Asie du Sud-Est et le Pacifique occidental. Le Canada continue donc de courir le risque d'une importation du virus de la rougeole.…”
