New York City has declared an end to the measles outbreak in the Williamsburg neighborhood in Brooklyn. The outbreak ultimately resulted in 654 cases, including 52 hospitalizations and 16 ICU admissions. Most of the cases were in children, and the vast majority were unvaccinated or undervaccinated. Health and elected officials implemented a variety of interventions in an effort to interrupt transmission, including mandatory vaccinations in affected communities and legislation eliminating non-medical exemptions for vaccinations required for school enrollment.
Measles cases worldwide continue to rise, and vaccine hesitancy is to blame. This week’s post is a brief update on the global measles resurgence.
California and New York have passed legislation in the last two weeks limiting exemptions for school-based vaccination requirements. In this post, we will analyze the recent legislative changes as well as their potential public health impacts.
As nationwide measles incidence continues its rapid climb toward the highest yearly total since the disease was declared eliminated in 2000, public health officials are struggling to effectively engage with insular communities—in this case, Ultra-Orthodox Jewish communities—where vaccine-preventable diseases like measles can gain a foothold as a result of low vaccination coverage.
Outbreak Observatory made a strong showing at the 2019 NACCHO Preparedness Summit, presenting the findings from recent observations, highlighting the value of this kind of collaborative and operational research, and engaging with potential future partners.
In addition to high-profile measles outbreaks, other vaccine-preventable diseases, including chickenpox, are making a comeback. An ongoing outbreak in North Carolina highlights the risks posed by low vaccination coverage in children.
After cutting global measles incidence from 2.6 million to fewer than 100,000 cases per year globally, measles may be on the rise due as a result of low vaccination coverage.
