The CDC's website for measles surveillance data now carries an unusual statement saying the update will not include the deaths reported by Pennsylvania. "At this time, available information does not establish whether measles caused or contributed to the deaths or whether the individuals died from other causes while infected with measles," the statement reads.
The Washington Post reported that the CDC changed the information on the page multiple times over the weekend. On August 29 at 2:33 pm ET, the chart listed total measles deaths for 2026 as "0." The next day at 12:09 pm ET, the chart was updated to "2," with a note reading: "Health departments make determinations about measles-associated deaths and share relevant information with CDC." By 3:23 pm ET, the two deaths had been deleted and replaced with an asterisk referencing the statement, which remains on the page.
The move follows the deaths of two unvaccinated people in Pennsylvania, which state officials confirmed last week. The CDC's action publicly questions the accuracy of the state's death determinations, a notable departure from the usual federal-state relationship in disease surveillance. The New York Times reported that Schwartz is behind the decision, though the CDC has not issued a public explanation beyond the website statement.
