Commuter with measles prompts California transit warning

After an infected passenger used commuter trains in the San Francisco area, officials sent out an official warning to passengers who may have come into contact with the man from February 4 to February 6.  The majority of Bay area residents is vaccinated, but the number of parents who are declining to vaccinate their children has risen in recent years.  An infected person is contagious several days before and after the rash appears.

Some symptoms of measles are a high fever, a runny nose, coughing and red, watery eyes.  The actual rash is highly visible on the skin.  Anyone born before 1957 is considered immune, and officials are urging vaccination.  An outbreak earlier in the year was traced to contact with an infected person at Disneyland.  Some complications of contracting measles are pneumonia, encephalitis, and problems with pregnancy, even miscarriage or blindness of the fetus.
