During a Cabinet meeting last week, US Health and Human Services Secretary Robert F. Kennedy Jr. downplayed what is now the second-worst measles outbreak in the US since the disease was declared eliminated in 2000.
Kennedy has claimed repeatedly that measles cases have plateaued, despite contradictory data from his own federal agencies.
On Friday, the health department in Texas the center of the outbreak that now spans multiple states reported 232 new cases over the past three weeks, 42% more than in the three weeks before that. New outbreaks have also been reported in Indiana and Ohio.
Overall, there have been at least 735 cases in 24 states this year, according to CNNs tally.
