This was the case for four vaccinated air travelers, as detailed in the latest MMWR case study. If measles infections occur, patients should consult their healthcare provider to discuss therapeutic options and benefits. Source: MMWR January 29, 2026.

Framing measles as an American policy failure is inaccurate and misleading. Under Health and Human Services Secretary Robert F. Kennedy’s leadership, the CDC has surged resources, including vaccines and therapeutics, nationwide to support state and local response efforts and contain outbreaks. We are setting the global standard for public health. -Dr. Ralph Abraham, CDC’s Principal Deputy Director
A million travelers have helped secure our borders against emerging pathogens. 🦠

Recently, CDC was on the ground in Texas, working closely with federal and state partners to strengthen readiness for the potential public health threat posed by New World screwworm. This engagement allowed CDC to highlight response planning, review preparedness efforts, and strengthen coordination and communication across jurisdictions.
To further support preparedness, CDC issued a Health Alert Network (HAN) Health Advisory to inform clinicians, public health authorities, and the public about recent New World screwworm animal cases in Tamaulipas, Mexico, which borders Texas. CDC continues to support state, tribal, and local health officials by providing technical expertise on diagnosis, clinical management, and reporting potential cases of New World screwworm.
