Measles Cases Reported in Louisiana, Missouri, and Virginia Linked to International Travel

In 2025, Louisiana, Missouri, and Virginia have confirmed their initial cases of measles, all of which are tied to international travel. The most recent case reported in Virginia involves a child aged between 0 to 4 years who traveled overseas, although health officials have not disclosed whether the child was vaccinated against measles.

Laurie Forlano, the state epidemiologist, highlighted the ease with which the highly contagious measles virus can spread, particularly through international travel. She emphasized that vaccination is the most effective tool for protection against the disease and plays a crucial role in preventing outbreaks.

The Virginia health authorities identified two medical centers, Kaiser Permanente in Woodbridge and Fredericksburg, as possible exposure locations, and they are actively working to trace individuals who may have been in contact with the infected child.

In Louisiana, the confirmed case involves an unvaccinated adult from the southeastern region of the state. The Louisiana Department of Health stated that this individual has been hospitalized and is currently in isolation until no longer contagious, while efforts are underway to notify those who may have come into contact with them.

Missouri's case pertains to a child associated with recent international travel who was visiting Taney County. Though the child’s age and vaccination status are unknown, the Missouri Department of Health indicated that the diagnosis occurred shortly after arrival, minimizing the risk of widespread exposure. Known contacts have already been reached for follow-up.

These developments occur against the backdrop of the largest measles outbreak in the United States in six years. While the Centers for Disease Control and Prevention has provided periodic updates, it has remained relatively low-key regarding the public health threat, only sending an alert to healthcare providers last month.

In Texas, the situation has escalated, with confirmed cases totaling 481, including instances involving young children. Health officials received 2,000 doses of the MMR vaccine from the CDC to manage the crisis. It is noteworthy that prior to this year, there had not been any measles-related deaths in the U.S. for a decade, with the last recorded death occurring in 2003.
