The Center for Disease Control and Prevention (CDC) is reporting 704 confirmed measles cases in the United States, the highest in 25 years.The common childhood infection was thought to be eradicated in the U.S. in the early 2000s, but has made a comeback, largely due to the spread of misinformation online claiming a link between the vaccine and autism. This has been proven to be false.There are no cases in Alabama, currently.Dr. Brian Gannon, pediatrician clinic director for the University Medical Center, explains how families can make sure they are protected. He said in countries where measles has not been eradicated, unvaccinated travelers are at risk going to those places.“Therefore, if you have an unvaccinated person who goes to one of those countries, that unvaccinated person can bring it back to the United States,” he said. “At this point, it does not appear that measles is spreading in the United States on its own. All of these outbreaks appear to be from travelers.”Gannon said the CDC is currently not recommending boosters to properly vaccinated adults. The only exception would be anyone who has had a change in immunity, like people going through cancer treatments. They should ask their doctor if a booster is needed.
