693 Is Pennsylvania’s Number. The Death Count Has Three Answers.

The claims

The fourth death Mostly True

A fourth death was reported on September 15, 2026. The verb is carrying weight, and the post chose it correctly.

The most recent case is an unvaccinated 18-year-old from Mifflin County. The county coroner, Andrea Alcalde, said the teenager died of acute disseminated encephalomyelitis, a rare neurological condition that can follow an infection.^[4] That followed a 40-year-old woman in Jefferson County, reported by that county's coroner on September 13, and two earlier deaths in infants in Lancaster County.^[4]

So four have been reported. Fewer than four have been established, which is where the claim needs its caveat rather than a correction.

Why the count has three answers

Three institutions are counting, and they disagree.

The gap is partly definitional. Pennsylvania counts a death as measles-associated when measles is present and the death occurs within a defined window; the federal record keys on measles as the underlying cause. Those two tests will not always return the same number, and neither is obviously wrong.

The gap is also political, and that part is not a technicality. The Hill reported that CDC excluded Pennsylvania's first two reported deaths from its weekly tally, which it described as a departure from the agency's normal practice of accepting state data.^[5] Governor Josh Shapiro has accused Health Secretary Robert F. Kennedy Jr. of intervening to keep the deaths out of the federal count. Kennedy denies directing any suppression, and earlier suggested the deaths might have been "fabricated by one of the Governor's hopeful staffers."^[4][5]

693 cases True

This one is exact, and it is a state figure rather than a national one.

The Pennsylvania Department of Health's September 15 release announces "693 measles cases have been confirmed across 38 counties in Pennsylvania so far in 2026," with 133 hospitalisations.^[1] Four days earlier the same series reported 676 cases in 37 counties and 124 hospitalisations, which gives a sense of the pace.^[2]

Anyone reading the post as a national figure would be badly misled, and in the direction of understatement. The CDC recorded 3,294 confirmed cases nationally as of September 10.^[3] Pennsylvania is roughly a fifth of that.

"4 total cases the last year Biden was president" Unproven

Half of this holds and half could not be checked.

The "no deaths" half is supported. Shapiro described the current deaths as the first measles deaths in Pennsylvania in 35 years, which places the previous one around 1991 and rules out any in 2024.^[4]

The case figure is the problem. Lamb appears to mean Pennsylvania, since he is replying to a Pennsylvania story and his other number is the state count. This check could not find Pennsylvania's 2024 total in any authoritative source. The CDC's data page reports national totals by year and lists which jurisdictions reported cases without publishing a per-state breakdown in its text; the state health department's historical dashboard does not surface a 2024 figure in retrievable form; and no news report located here states one. What is verifiable is the national 2024 total of 285 cases, so the figure is certainly not a national one.^[3]

Unproven is a statement about this check's reach, not an accusation. Four is a plausible Pennsylvania total for a quiet year, and the direction of the comparison is not in doubt: the state went from a handful of cases and no deaths to 693 cases, 133 hospitalisations and four reported deaths. A reader should simply not treat the specific "4" as sourced.

What the national picture shows

The framing around both posts is that something changed, and on the national numbers it plainly did. The CDC counted 285 cases in 2024, 2,289 in 2025 and 3,294 by September 10 of this year.^[3] Nationally this is the highest total in more than three decades, and 1992 was the last year with four measles deaths.^[4]

On cause, this site has already examined the claim that the surge traces to immigration and found it false: CDC data showed 16 of the cases involved international visitors, with declining vaccination the driver.^[10] Pennsylvania's own figures point the same way. Of its 693 cases, the department identified four in people who were appropriately vaccinated for their age, under one percent, and none were hospitalised.^[2]

One caveat runs the other way, and it belongs here. Paul Offit has argued that two deaths in roughly 400 cases implies a mortality rate of one in 200 against an expected one in 1,000, which "suggests that the outbreak is much worse than is claimed" and that many infections have gone unreported.^[6] If he is right, the case counts above are floors rather than totals, and the death-count dispute is being conducted over an incomplete denominator.

What would settle the open questions: a completed Pennsylvania review of the Jefferson County death and the Mifflin County death would move the state's confirmed total; a CSTE standardised definition would give the state and federal counts a common test; and a published Pennsylvania case series for 2024 would resolve the comparison Lamb is drawing.
