According to ABC News, an unvaccinated UC Berkeley student who commuted to and from the campus has contracted measles on a trip abroad and may have infected fellow passengers.
Although those who have received the vaccine or previously contracted the disease are not likely at risk, measles is highly contagious among those who have never been vaccinated.
BART reports that the infected individual rode between El Cerrito del Norte and Downtown Berkeley stations from Tuesday, Feb. 4, to Friday, Feb. 7, during both morning and evening commute hours.
As consolation, BART officials noted that the trains are cleaned using "industrial-strength disinfectant" each time they reach the end of the line.
The Centers for Disease Control and Prevention lists the following symptoms to watch out for:
• Measles Rash
• Blotchy rash
• Runny nose
• Red, watery eyes (conjunctivitis)
• Feeling run down, achy (malaise)
• Tiny white spots with bluish-white centers found inside the mouth (Koplik’s spots)
