An 18-month-old French girl who recently arrived in Mexico has been diagnosed with measles. Health officials are trying to locate the other passengers who were aboard her plane, and the Mexico City neighborhood where she is staying is under quarantine. The 2007 case of measles was in a traveler; no Mexican national has been diagnosed with measles in Mexico since 2004. The case is yet another example of the risks of low vaccination rates in other countries. Recent measles cases in Boston, Massachusetts were linked to a French consulate worker. The United Kingdom believes its surge in cases is due to contact with people in France and other European countries where outbreaks have been spreading.
