““Measles cases tripled since 2024” — checking the CDC data”

84 ±4 Largely accurate — one key omission
What we found

The tripling is real for confirmed cases: 285 in 2024 against 892 through June 2026. What the claim omits is the baseline — 2024 was among the lowest counts on record, so “tripled” describes a return toward the ten-year average, not an unprecedented surge. Vaccination-rate data explains most of the regional variation.

    The CDC’s June table mixes confirmed and probable cases for TX and NM — the true confirmed count is closer to 840.

      Confirmed — I’ve flagged it for revision. The verdict doesn’t change (the low-baseline point stands either way) but the ledger should be precise.

  2. R. Bishara EDITOR JUL 4

    Score revised 86 → 84 after a reader (below) flagged that the June 2026 figure includes probable cases in two states. The ledger now separates confirmed from probable. Good catch — this is what the discussion is for.
