This follows a recent outbreak in Fortworth Texas: http://txnaturalpediatrics.com/2013/08/20/news-break-refused-mmr-vaccine-stay-at-home/
Health officials are trying to get the word out that a University of California, Berkeley, student may have exposed classmates and strangers to measles. A student who contracted measles, likely during a trip overseas, had spent time in and around campus and commuting to and from his home on Bay Area Rapid Transit. As the Centers for Disease Control and Prevention notes, measles spreads through coughing, sneezing or breathing and "any child who is exposed to it and is not immune will probably get the disease." Measles start out much like a common cold, with high fevers, red eyes and a telltale rash. Children are particularly susceptible: About 10% of them who get measles come down with ear infections, and roughly 5% end up with pneumonia. One or two of 1,000 children with measles die, according to the CDC.
Since we cannot raise our kids in a bubble, we recommend that you consider vaccinating your child.
