A tularemia outbreak in Sweden has reached nearly 800 cases this year and is poised to surpass 2015 as the highest yearly total in more than 50 years, causing concern among public health officials. This Outbreak Thursday, we will look at the epidemiology of the current outbreak as well as longer-term trends, including the possibility that this outbreak could signal elevated incidence in future years.
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.
Eastern Equine Encephalitis (EEE) has been reported in Massachusetts for the first time since 2013. The state has reported 4 cases so far in 2019, including 1 death, and the “critical risk” areas are growing steadily and quickly approaching the Boston area. EEE is a relatively rare, but potentially fatal, disease in the US, and increased incidence could indicate that factors such as humans venturing further into high-risk areas like swamps and climate change could place humans at increased risk for EEE and other vectorborne diseases in the coming years.
