The Health Department says it has identified 16 cases of measles in New York City.
Seven adults and nine children in northern Manhattan and the Bronx tested positive for the virus. Four had to be hospitalized. Of the children infected, most were too young to be vaccinated. But two have parents who refused to vaccinate them.
The Health Department is asking any people who think they may be infected to avoid contact with others and call their doctors. Officials are also urging residents to make sure they're vaccinated.
Measles is a highly contagious viral infection that can spread by air. Symptoms include a rash and high fever, accompanied by cough, red eyes, and runny nose, and typically last five or six days. The first symptom to appear is usually a rash on the face, but infected people can spread the disease for four days before the rash develops.
The department says as many as one in three people who contract the virus develop complications, and those most at risk are infants under one year, people with weakened immune systems and pregnant women who are not vaccinated.
Residents who want to get vaccinated can call 311 to find out where to go.
