The fever can spike above 104°F when the rash appears. A person is contagious from 4 days before the rash to 4 days after, and the virus can hang in a room for up to two hours after they leave.

Executive Order 65, signed by Governor Hochul on October 5, 2026 and in effect through November 4, 2026, lets more professionals give the MMR vaccine (paramedics and advanced EMTs, pharmacists for children 2 and older, midwives) and lets registered nurses order measles tests.
Call your doctor, pharmacy or county health department; many county health departments are running free MMR clinics during the outbreak. In NYC, the Health Department's Fort Greene clinic in Brooklyn gives low- or no-cost shots to anyone 4 or older, regardless of immigration status.
Call your health care provider or local health department right away, before going in. If you have never been vaccinated, an MMR shot within 3 days of exposure, or immunoglobulin within 6 days, may prevent measles or make it milder (NYSDOH). Watch for fever and rash for 21 days.
