More measles cases have been confirmed in New Jersey and Kentucky as health officials work to treat patients in an ongoing outbreak in Texas.

New measles cases have been confirmed in New Jersey and Kentucky with the one common factor being a lack of measles vaccinations.

The New Jersey Department of Health confirmed an initial measles case on Feb. 14 in an unvaccinated individual, and by Feb. 20, two additional cases were identified in people who had close contact with the original patient.

The number of confirmed measles cases in western Texas grew to 146, and it is possibly spreading to the central part of the state and neighboring New Mexico, health officials said Friday.

The cases identified in New Jersey are separate from a serious measles outbreak that has swept through West Texas in the last month, with doctors diagnosing 124 cases in nine counties.

In the notice issued Friday, the agency also encouraged Texas residents to ensure they are up-to-date with immunizations. Six other states including Alaska, Georgia, New Jersey, New Mexico, New York and Rhode Island have also reported measles infections.
