Texas has declared the end of the measles outbreak that began in West Texas in late January, the Department of State Health Services said Monday. The agency said more than 42 days—two full incubation periods—have passed without a new infection in the affected counties, meeting the benchmark used by public-health authorities to close an outbreak. The virus infected 762 people, hospitalised roughly 100 and killed two young children, according to state and federal data. Health officials traced many of the early cases to exposures in Canada and Mexico before the virus spread to other U.S. states, driving the nation’s worst measles surge in three decades. Commissioner Jennifer Shuford credited testing, vaccination drives, monitoring and public-awareness campaigns with containing the highly contagious virus. The state will continue surveillance for new cases and promote the measles, mumps and rubella vaccine, which remains the primary defence against the disease.
