BERKELEY -- UC Berkeley opened an emergency measles clinic Saturday, a day after a second student was diagnosed with the disease.
According to a notice posted on the University Health Services website, the unidentified student attended classes on campus over the past week while infected.
Campus officials worked with the city's Public Health Department to notify anyone who may have been exposed to the disease.
The student is currently in isolation.
This is the second reported case of measles at the university. The first case was reported in February when a student, recently back from a trip to Asia, contracted the disease yet still attended classes on campus.
That student, who most likely was not vaccinated, also infected two relatives, who remained in isolation while they recovered.
Concern grew when health officials announced that the student had used BART to travel from his home near the El Cerrito Del Norte station in Contra Costa County to UC Berkeley, potentially infecting thousands of commuters and classmates.
Measles is an air borne disease that spreads when an infected person coughs or sneezes. Symptoms include high fever, runny nose, coughing and watery red eyes and can begin one to three weeks after exposure, according to the Centers for Disease Control. A rash develops on the face and neck two to three days after the fever begins, and spreads down the body.
UC Berkeley students who have not been vaccinated can contact University Health Services at 510-643-7177, while Berkeley residents can contact the Berkeley Department of Public Health at 510- 981-5300.
There have been 51 confirmed measles cases in California this year, including two in Alameda County and four in Contra Costa County.
