28% fewer hepatitis a cases in Venezuela: 34 in the last 30 days

The full briefing

Full 2026 picture: Hepatitis A in Venezuela — reported cases by year, monthly records and every briefing for this pair.

Venezuela reported 116 hepatitis a cases in the 90 days to 15 November. 34 of them came in the 30 days to 15 November, against 47 in the 30 days before.

Why it matters

Venezuela accounts for 2.5% of the hepatitis a cases reported to ENCLAI worldwide so far in 2026. It ranks 12 of 25 reporting countries.

The numbers

Period	Reported cases
Last 30 days (to 15 November)	34
The 30 days before that	47

2026 so far (ENCLAI export)	359

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.

Retained reporting context

Sources and limitations

• ENCLAI surveillance dataset — methodology, coverage and limitations (ENCLAI · 2026-11-15)
• Data sources — aggregate coverage by region and source type (ENCLAI · 2026-11-15)

• 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.
