Domestic Travel Becomes a Growing Measles Risk in the US
International travel was once the primary source of measles cases in the United States, but domestic travel is now becoming a growing risk. In South Carolina, the outbreak reached Washington state five times over a two-week period.
The spread highlights a new challenge for state health authorities, which must now track transmission across the country rather than focus primarily on cases arriving from abroad. The limited reporting provided does not specify the number of people infected or the circumstances behind the five transfers.
