State officials have issued a health alert for measles, stressing vaccinations after 15 cases of the illness were reported across the state.

State Epidimiologist Gil Chavez says we've seen infections in three Bay Area Counties. Infections start with a fever.

Fevers can be as high as 105 degrees, and is followed by a cough, runny nose and eye redness. 

Measles is also characterized by rashes that start on the face and spread.

Earlier this month, an infected UC Berkely student with the rode BART and prompted health warnings.
