The outbreak is believed to have spread to New Mexico, Oklahoma and Kansas, with the WHO reporting related cases in Mexico.
A second school-aged child in West Texas has died from a measles-related illness, a hospital spokesman confirmed on Sunday, as the outbreak continues to swell.
Aaron Davis, a spokesperson for UMC Health System in Lubbock, Texas, said that the child was “receiving treatment for complications of measles while hospitalised” and was not vaccinated. The hospital declined to say which day the child died.
Neither the US Centres for Disease Control and Prevention nor the Texas State Department of State Health Services include the death in their measles reports issued on Friday.
