Abstract

Background: Measles is a vaccine-preventable infectious disease whose outbreaks generally originate from exposure to populations with low vaccination coverage. Methods: This study compared the rates and morbidity of measles cases in the district of Tel-Aviv during two outbreaks (2012 and 2018–2019) by citizenship and geographic location. Results: There were 67 pediatric cases reported in 2012 and 222 in 2018–2019. Cases were more likely to have pneumonia in 2012 as compared to in 2018–2019 (58.2% versus 6.3%) and less likely to report a single vaccination dose (9.5% versus 22.8%, respectively). In 2012, the majority of cases were among children without legal residence (CWLR), while in 2018–2019, they were the minority of cases (N = 54, 80.6% versus N = 51, 23.0%, respectively). In both outbreaks, CWLR were more likely to be less than one year old (the recommended age for the first dose of measles vaccination), unvaccinated or with unknown vaccine status, to be treated in a tertiary care center, and to have pneumonia than children with Israeli citizenship (CC). In both outbreaks, CWLR lived in a concentrated neighborhood in Southern Tel Aviv. Conclusion: While the two measles outbreaks differed in overall morbidity, in both outbreaks CWLR presented with a more severe clinical presentation and were less likely to be vaccinated (in part due to their younger age) than CC. The geographically concentration of CWLR was distinct from that of the CC in both outbreaks. Healthcare professionals should promote vaccination uptake and increase parents' awareness to early signs of the disease.
