If you are vaccinated, then you don't have much to worry about. According to this: http://www.cdc.gov/measles/vaccination.html http://www.cdc.gov/measles/vaccination.html "Measles can be prevented with the MMR (measles, mumps, and rubella) vaccine. One dose of MMR vaccine is about 93% effective at preventing measles if exposed to the virus, and two doses are about 97% effective. In the United States, widespread use of measles vaccine has led to a greater than 99% reduction in measles cases compared with the pre-vaccine era. " And most people are vaccinated: http://articles.latimes.com/2013/sep/12/science/la-sci-sn-cdc-measles-vaccines-20130912 http://articles.latimes.com/2013/sep/12/science/la-sci-sn-cd... "The federal government targets 90% childhood vaccination rates. Nationwide, Americans are hitting or exceeding that goal for measles, mumps and rubella; for polio; for hepatitis B; and for varicella (the virus that causes chicken pox). Americans missed targets for diphtheria, tetanus and pertussis, and for Hib and PCV vaccines." However, there is something strange happening among the affluent in California, and so a great many children are vulnerable: http://www.wired.com/2015/02/tech-companies-and-vaccines/ http://www.wired.com/2015/02/tech-companies-and-vaccines/ "We selected more than 20 large technology and health companies in the Bay Area and researched their day care offerings. Of 12 day care facilities affiliated with tech companies, six—that’s half—have below-average vaccination rates, according to the state’s data. And those six have a level of measles vaccination that does not provide the “herd immunity” critical to the spread of the disease. Now, this data has limitations—most critically, it might not be current. But it also suggests an incursion of anti-science, anti-vaccine thinking in one of the smartest regions on Earth."
