About this site
This site gathers, day after day, what the Congolese authorities publish about the 17th Ebola outbreak, together with the WHO situation reports that fill some of the gaps — and nothing else.
From bulletin to chart
-
The bulletin is archived
Every PDF published by the INSP is downloaded and kept as is, as are the WHO weekly reports that complete some of the series. The original stays available — that is what makes the figures on this site checkable.
-
The reports are read
A program reads the PDF's tables, then every report is read in full — including the prose around them, whose wording changes from one bulletin to the next and which sometimes carries figures the tables leave out. Checking is therefore manual as well, bulletin by bulletin. A value that does not reconcile is dropped rather than approximated.

The site is updated
With every new bulletin, every page of the site is remade with the new figures. What you read here is exactly what was checked against the bulletin — nothing is recomputed when you open the page.
How to read these figures
Confirmed cases and deaths are totals since the start of the outbreak. Only new cases and deaths — the “24h” columns, or “(+…)” on the map — are daily figures, announced by the latest bulletin. The fatality rate covers confirmed cases only, and the outcome of the most recent cases is not yet known: it describes the severity observed so far, not an individual's risk of dying from the disease, and it will keep moving. New cases (24h) is taken as published in the latest bulletin — so it does not always match the gap between two successive cumulative totals, since retroactive revisions land in the totals but not in that figure.
Two known limitations. National figures are sometimes published before the province and health-zone breakdown, so a temporary gap between levels is normal. And the authorities sometimes revise figures retroactively — those revisions are reflected here as they come, unsmoothed.
Data sources
The figures shown come mainly from the Situation Reports (SitRep) published by the National Institute of Public Health (INSP) of the DRC. Only three contact-tracing readings (23 and 29 May, 28 June), which the day's SitRep did not give, come from the World Health Organization's (WHO) Weekly External Situation Report. Both sources are archived and available in the Situation reports tab.
Methodology
This site is powered by a tool that's actively developed and supervised: it fetches each newly published SitRep and extracts the key figures (confirmed cases, deaths, recoveries, breakdown by province and health zone), generally once a day. Every report is then read in full — the tables as well as the prose — and the extractions are checked by hand, bulletin by bulletin, with manual correction when needed (a bulletin's layout changing, fixing a numbering error, etc.). The WHO weekly reports are read the same way and are used to complete the series the INSP SitRep does not cover. Data may be revised retroactively by health authorities (harmonisation between provinces, reclassification of community deaths): such revisions are reflected on the site automatically as soon as they're published.
Known limitations
Official reports mix data at different levels of detail (national, provincial, health zone), sometimes in different formats, which can occasionally produce minor inconsistencies or approximations. National figures are also sometimes published before the province and health zone breakdown, causing a temporary lag between these levels.
Update frequency
The site checks for a new SitRep once a day. The date of the latest official SitRep included is always shown at the top of every page.
Access to the data
All the data shown on this site comes from the official bulletins archived in the Sources and bulletins section, where each one can be read as its original PDF.
