Key Evidence

Verified September 5, 2026
  • Multiple September 4 reports said Lancaster County Coroner Stephen Diamantoni determined that a six-week-old infant died from measles.

  • Earlier NBC News and CNN reports said the coroner had attributed the death to a ruptured spleen and did not consider measles the cause, indicating that the case was previously disputed.

  • The child reportedly had Amish lethal microcephaly, a rare genetic condition associated with vulnerability to respiratory illness, but that background does not negate the later reported coroner determination.

The reporting

What the Evidence Shows

The claim is supported by several reports published or updated on September 4, 2026. The Washington Post, The Guardian, The New York Times and The Hill all reported that Lancaster County Coroner Stephen Diamantoni had determined that a six-week-old infant’s death was caused by measles. The reports identify the child as belonging to Pennsylvania’s Amish community and say the infant died the previous month.washingtonpost.comwashingtonpost.comInfant died of measles in Pennsylvania, coroner confirmstheguardian.comtheguardian.comSix-week-old child in Pennsylvania dies from measles, coroner says |...+3 more

Earlier reporting presented a different account. NBC News reported that the Pennsylvania Health Department had classified the death as measles-associated, while the coroner said he believed the infant died from a ruptured spleen rather than measles. CNN’s supplied summary likewise says Diamantoni had not changed that determination. Those reports were published about a week before the September 4 accounts, so they reflect the earlier dispute rather than the later reported finding.nbcnews.comnbcnews.comCoroner says baby with measles in Pennsylvania died of a ruptured spleencnn.comcnn.com6-week-old infant died of measles, Pennsylvania county coroner says

The available results do not include the coroner’s underlying death certificate, autopsy report or a direct statement from the Pennsylvania Department of Health explaining the change. They do, however, show multiple contemporaneous news organizations attributing the later conclusion to the county coroner. On the supplied evidence, the statement that the infant’s death was confirmed to have been caused by measles is accurate, with the earlier disagreement providing important timing and context.
