Plain-English overview

COVID-19 surveillance now mixes clinical data, wastewater, and variant dashboards depending on the country. Official pages explain what each chart measures.

What official signals usually mean here

A signal might be a national situation report, hospital capacity note, or wastewater uptick - read the footnotes on the linked page.

How OutbreakThreat tracks it

We pass through publisher metadata and dates; we do not project your personal risk from a regional curve alone.

Current outbreak signals

Each notice shows the publisher's event date and source. Geography is whatever that notice stated. Counts on this page are the number of ingested notices, not national case totals. Map: filtered map.

What it is

Respiratory illnesses affect the lungs and airways. Public dashboards and wastewater can show when activity is rising in a community.

Symptoms (general)

Symptoms vary by illness but may include cough, fever, sore throat, fatigue, or shortness of breath. This page is informational only.

How it spreads

Many respiratory pathogens spread through respiratory droplets and aerosols, especially in crowded indoor spaces.

Prevention (general)

Follow local public health guidance, stay home when ill, improve ventilation where possible, and consult a clinician for personal medical decisions.
