Hantacases Hantavirus situational awareness

Hantavirus situational awareness

Hantacases monitors hantavirus signals across 14 official surveillance feeds — WHO Disease Outbreak News, ECDC, CDC HAN, RKI SurvStat, CDC NNDSS, Brazil SVSA, PAHO, GDELT, and six more. Counts and signal-clusters are aggregated server-side every 30–60 minutes; the view below shows rolling 30-day totals plus the previous 30 days for delta context.

About this data

Hantaviruses are a family of zoonotic RNA viruses transmitted to humans primarily through aerosolised excreta of infected rodents. Two distinct disease syndromes circulate worldwide: Hantavirus Pulmonary Syndrome (HPS), caused by New-World viruses such as Sin Nombre virus in North America and Andes virus across the Southern Cone, and Haemorrhagic Fever with Renal Syndrome (HFRS), caused by Old-World viruses such as Hantaan, Seoul, and Puumala across Eurasia. Annual case loads range from sporadic events in low-incidence regions to several thousand HFRS notifications per year in endemic ones.

How we collect the data

The dashboard ingests from fourteen official surveillance feeds operated by national or supranational public-health agencies. Adapters run on cron schedules between 30 minutes (high-cadence news and alert channels such as GDELT, the WHO Disease Outbreak News service, and the CDC Health Alert Network) and 24 hours (weekly or quarterly counts feeds such as RKI SurvStat for Germany, CDC NNDSS for the United States, Brazil SVSA for Brazilian states, and the ECDC Communicable Disease Threats Report for Europe). Each adapter is responsible for its own fetch, normalisation, deduplication, and persistence; failures are isolated per adapter and recorded to a source_health table that drives the status pills you'll find at the bottom of this page.

Two persistence styles

Adapters fall into two categories. Event-style feeds (WHO DON, PubMed, GDELT, PAHO, CDC HAN, ECDC News, ECDC CDTR, China CDC, ArcGIS Outbreak, KDCA) emit one row per source-side artefact — a DON report, a published paper, a news cluster, a HAN alert. Counts-style feeds (Argentina Boletín, RKI SurvStat, CDC NNDSS, Brazil SVSA) emit structured per-jurisdiction confirmed-case counts at the natural granularity of the upstream — per-province per-week, per-(year, ISO-week), per-state per-week, or per-region per-week. The world map visualises both at once: confirmed cases drive the country fill colour, event signals drive the per-country stroke overlay.

The rolling 30-day window

Every metric on this page is calculated over the most recent 30 days, compared against a parallel 30-day window pushed one day into the past. That overlap (29 of 30 days are shared between the two windows) means the delta reflects "what changed in the rolling view since yesterday" rather than a block-to-block comparison. The world map uses the same 30-day aggregate; the case-colour scale is calibrated so that red — the most attention-grabbing tier — is reserved for ≥500 confirmed cases in the window, not for the background level of routine surveillance chatter every covered country produces.

Severity classification

Severity hints are derived from a small set of pure rules: cluster detection on news feeds (three or more articles with the same normalised headline across distinct domains within 24 hours promotes to watch), explicit alert metadata on CDC HAN (cdc_health_alert → alert, cdc_health_advisory → watch), and a keyword-based classifier that recognises explicit outbreak vocabulary (cluster, cases confirmed, death toll, fatality). The dashboard is informational; severity hints are never authoritative and never replace a public-health authority advisory.
