Texas health officials on Monday declared the state’s measles outbreak over, saying no new infections have been detected for more than 42 days, twice the virus’s maximum incubation period. The announcement came from the Texas Department of State Health Services (DSHS), which confirmed the last outbreak-linked case was reported on 1 July. The outbreak began in late January in a largely undervaccinated Mennonite community in Gaines County and spread across West Texas. In total, 762 infections were confirmed, more than two-thirds of them in children. Roughly 100 patients required hospital care, and two unvaccinated school-aged children died. State officials credited aggressive testing, vaccination drives and public awareness campaigns for containing the highly contagious virus. “This success reflects the tireless work of public-health professionals across Texas,” DSHS Commissioner Jennifer Shuford said in a statement, while cautioning that continued vigilance is needed as measles circulates elsewhere in North America. The Texas cases accounted for a significant share of the 1,356 infections the US Centers for Disease Control and Prevention has logged nationwide this year—the highest national total in more than three decades. With ongoing outbreaks in Canada, Mexico and other US states, health authorities urged parents to ensure children receive the two-dose measles, mumps and rubella vaccine, which is 97 % effective at preventing infection.
