The full briefing

Full 2026 picture: Tuberculosis in United States — reported cases by year, monthly records and every briefing for this pair.

The US reported 1,743 tuberculosis cases in the 90 days to 26 September. 316 of them came in the 30 days to 26 September, against 836 in the 30 days before. The same 30 days a year earlier had 662.

Why it matters

The US accounts for 2.4% of the tuberculosis cases reported to ENCLAI worldwide so far in 2026. It ranks 4 of 21 reporting countries. 2025 closed at 7,158 cases, 31% below the three-year baseline of 10,333 a year. 2026 so far stands at 4,550.

What the source says

These figures come from official surveillance reports. They count reports, not people. They are not an incidence rate, the rate of new cases in a population. They do not cover the whole population. The reporting periods do not match these dates exactly. Some reports are incomplete or still in progress. Some run past the window. Some reports do not say which date they use: symptom onset, notification, or confirmation.

Caveats

  • A change between two 30-day windows can come from reporting timing as much as from transmission. The source does not say which.

Weeks starting 2026-06-22 through 2026-09-07

A retained retrospective weekly reported-count series across included reporting countries. Country membership and reporting completeness can vary by week. Missing weeks remain gaps. This is a separate report-series measure; it does not establish exact incidence or laboratory confirmation.

Sources and limitations

  • Window. Each quantity keeps its recorded source-selection dates and coverage notes. Dated batches and weekly or genomic observations retain their separate measures. Publication or capture dates do not establish case onset, equal cohorts or period completeness.
  • Denominator. The retained counts do not establish complete populations, equal reporting cohorts or incidence rates. Source period bounds and definitions can differ.
  • Case definition. Case definitions are set nationally and change over time. Counts for the same disease in different countries may not be counting the same thing.
  • Revisions. Agencies restate figures. Values here are as reported at the time of publication; see the update history below.

ENCLAI counts reflect verified records available from reporting sources for the stated window. They are not estimates of total incidence and should not be interpreted as medical advice. Full methodology: the dataset.
