CDC urgers travelers to get immunizations

The U.S. Centers for Disease Control and Prevention is urging U.S. travelers going abroad to be properly immunized against measles.

The CDC says travelers to countries that have recently had large outbreaks, including France Britain, Spain, Switzerland, India and areas of Africa and Asia, have been returning to the United States and bringing the measles back with them, according to the L.A. Times.

"Every traveler needs to make sure they are immune to measles," Dr. Phyllis Kozarsky, a consultant for the CDC's division of global migration and quarantine, said, the L.A. Times reports.

Kozarsky said that those who were properly vaccinated, or those who had measles as a child, have a lifetime immunity. Those who are unsure of their status can get checked with a simple blood test. The warning applies to what is considered regular measles, not a new strain or vaccine-resistant superbug.

In an advisory issued by the CDC, American travelers over the age of six months who have not been vaccinated and are known to lack immunity are urged to receive the measles, mumps and rubella vaccine, or MMR. It requires two shots that are spaced 28 days apart from one another.

Measles is passed in droplets generated by coughing or sneezing and is dangerous, in part, because it can cause severe complications such as pneumonia or encephalitis.
