On September 3, 2019, New York City officially announces the end of the measles outbreak. New York City recently had the largest measles outbreak in the last three decades. According to the New York City Health Department1, beginning in October 2018, there have been 654 reported cases, 52 measles-related hospitalizations, and 16 intensive care hospitalizations. Among the measles cases 73% were unvaccinated, 7% were incompletely vaccinated, and 15% were unaware of their vaccination status. The Health Department required unvaccinated people in specific ZIP codes to receive the measles, mumps and rubella vaccine, and recommends all New Yorkers to get vaccinated in order to prevent the transmission of the disease. In response to this outbreak, New York State Governor Andrew M. Cuomo has signed a bill in June2 that would end non-medical exemptions from mandatory vaccinations for students.
