TUCSON - Arizona has sent an additional $350,000 in emergency funding to Pima and Pinal counties to help combat a measles outbreak.
The money allocated from a special state health crisis fund is on top of $50,000 allocated last month by Gov. Janet Napolitano to help pay for health workers and lab testing.
The new money will help pay for 10,000 vaccine doses and lab tests.
The measles outbreak began in February when an infected Swiss tourist sought medical treatment at a Tucson hospital. Because measles can be spread through the air, hundreds of people were potentially infected.
Since then, 21 cases have been confirmed in Pima County, and last week Pinal County reported its first case.
Vaccination clinics are being held in both counties.
