NEW YORK - The city's measles outbreak is growing. 

The Health Department has confirmed an additional three cases, bringing the total to 19 patients. 

The original cases were reported in the Bronx and northern Manhattan, but it's unclear what borough the latest patients are from. 

Health officials are reminding everyone to make sure their family members are up to date on vaccinations, especially young children. 

Measles starts with a fever, cough, runny nose, sore throat and watery eyes. The patient may then develop little white spots on their gums and the inside of their cheeks after two or three days, followed by a rash.
