"This 9171 subtype "continues, unfortunately uninterrupted, across multiple jurisdictions," David Sugerman, who leads the CDC measles response, said on the call. According to the Times, local health officials are pessimistic that they'll be able to stamp out the virus' spread, saying that vaccination efforts have had "limited" impact. As Ars reported previously, vaccination rates are dangerously low in two measles hotspots: northwestern Mohave County, Arizona, and the southwest health district of Utah."
"Vaccination rates among kindergartners in the 2024-2025 school year were 78.4 percent and 80.7 percent, respectively. That's well below the 95 percent target needed to keep the virus from spreading onward in the communities. In addition, public health officials in Arizona and Utah have reported barriers to responding to the outbreak. Around a quarter of cases don't know how they were exposed, suggesting cases and exposures are being missed."
"David Kimberlin, who sits on a panel of experts that analyzes measles data for the United States' elimination status review, told the Times, "It would not surprise me in the least if there's continued spread across these next several months." To date, the CDC has tallied 1,723 measles cases across 42 states. Most (87 percent) of those cases were linked to outbreaks, of which there have been 45 this year."
Measles transmission continues across multiple jurisdictions with a 9171 subtype persisting despite response efforts. Vaccination rates in key hotspots are dangerously low, with kindergarten coverage at 78.4 percent and 80.7 percent in affected areas, far below the 95 percent threshold needed to prevent spread. Public health officials report barriers to outbreak response, including unknown exposures for roughly a quarter of cases and at least one probable case where the individual refused to cooperate. Experts warn of likely continued spread over coming months. The CDC has recorded 1,723 cases across 42 states, linked largely to 45 outbreaks this year.
