In the UK, the Thames Valley Health Protection Unit has issued a letter to the parents of every single child via the local Education Authorities because there has been an increasing number of cases of measles during 2011, especially among children. A similar rise has been observed in other countries in Europe, especially France, but also including Spain, Romania, Bulgaria and Germany. What has been happening is that folks have been away on vacation, and as a result their unimmunised children have been picking up measles, and then bringing it back.
In the US it is a similar story, they are on course to have its worst outbreak of measles in more than a decade. Travellers are catching the highly contagious illness while on vacation, then bringing it back to the U.S.
What is going on here?
