(Reuters) -The Texas health department reported a total of 718 cases of measles in the state as on Friday, an addition of one case since its last update on Tuesday, marking the lowest increase since the outbreak began in February.

The latest case was reported in Gaines County, the epicenter of the outbreak, which reported a total of 406 cases.

The outbreak in Texas, which has led to the deaths of two unvaccinated children, is centered in a Mennonite community and has spread to neighboring states including New Mexico, Oklahoma and Kansas.

New Mexico's health department reported 74 cases, an increase of three more cases from its last update on Tuesday. Most of the state's cases are from Lea County, adjacent to Gaines County in Texas.
