InfectRisk tracks respiratory infections — not haemorrhagic viruses
This overview aggregates official outbreak notifications worldwide, including events such as Ebola or hantavirus that fall outside the respiratory infections the app tracks. The InfectRisk app itself shows live data on influenza, COVID and RSV across 36 countries — based on national surveillance systems such as RKI, ECDC, CDC and UKHSA. If you want to know how high respiratory activity is in your area right now, the app is the direct answer.
