Kennedy Jr., a vaccine critic, is the new US Health Secretary amid the outbreak.A child in West Texas has died from measles, marking the first reported fatality from the disease in the US in nearly a decade, state health officials announced on Wednesday.The "school-aged child" who was unvaccinated died at a children's hospital in Lubbock after being hospitalized last week and testing positive for measles, according to a press release from the Texas Department of State Health Services.The death comes as Texas battles a growing measles outbreak that has surged from a handful of cases to at least 124 infections since early February, mostly among children, state health officials said. At least 18 people have been hospitalized so far, most of whom are unvaccinated or have unknown vaccination status, according toAnother nine cases have been confirmed in eastern New Mexico close to its border with Texas, bringing the total to more than 130 across the two states, per Texas DSHS.Measles, a highly contagious airborne virus, has a fatality rate of one to three deaths per 1,000 reported cases, according to the Centers for Disease Control and Prevention.Lara Anton, senior press officer of the Texas Department of State Health Services, told Business Insider that it is very difficult to stop the spread of measles. Not only does an unvaccinated person have a 90 percent chance of being infected if exposed, an infected person can be contagious without knowing it for up to four days, Anton said."When people register their children for school in kindergarten through seventh grade, they provide updates to us and the school districts on the vaccination coverage in their district," Anton said. "Generally the coverage level statewide has dipped down in recent years."Measles death is uncommon. The last reported measles death of an adult in the US occurred in 2015 when a Washington woman contracted it at a health clinic, CDC data shows. Anton said a child also died of measles in Texas in 2018.Robert F. Kennedy Jr., a vaccine critic, was confirmed as US Health Secretary this month despite opposition from medical professionals and some members of Congress. He has, however, pledged to maintain existing vaccination programs."We are following the measles epidemic every day," Kennedy said during a meeting with President Donald Trump's cabinet at the White House. "Incidentally, there have been four measles outbreaks this year. In this country last year there were 16. So, it's not unusual. We have measles outbreaks every year."He also mentioned that two people had died in the outbreak, but the Texas DSHS was only able to confirm one death so far.The Centers for Disease Control and Prevention and the Department of Health and Human Services did not immediately respond to requests for comment.
