Bird Flu FYI is a free, ad-free map of confirmed H5N1 / highly pathogenic avian influenza (HPAI) outbreaks worldwide. As of 2026-10-21, it is tracking 18,149 confirmed outbreak records across 116 countries, with 193 reported in the last 30 days, covering wild birds, poultry, mammals, livestock and human cases. Updated daily from official sources; this is not a live feed. Last updated 2026-10-21.

Outbreak data is aggregated from official, openly-licensed animal- and public-health sources and reprocessed (geolocated and de-duplicated) for mapping. Locations are often approximate (locality, county or country centre). No official end or all-clear date is tracked. On the map an outbreak counts as “recent” for a fixed display window after its confirmation date (about 8 weeks for poultry, 13 weeks for livestock, 30 days otherwise) and is simply an older detection after that — a display convention, not a statement about its real-world status.
The answers below describe what Bird Flu FYI shows and how it works. They are general information compiled from official public sources, are not medical, veterinary, biosecurity or public-health advice, and may be out of date or incomplete. Do not rely on them for any decision; confirm the current situation with your agriculture or health authority.
Bird Flu FYI maps H5N1 avian-influenza (HPAI) outbreaks that have been publicly confirmed by official animal- and public-health sources (FAO EMPRES-i, USDA APHIS, EFSA/ECDC, Australia’s DAFF and WHO) across the United States, Europe, Australia and worldwide. The map is refreshed once a day from those sources and reflects what they had published at the last refresh — it is not a live feed and does not show every outbreak. Open the map to view confirmed detections and filter by wild birds, poultry, mammals, livestock or human cases. For the current situation in any area, check the relevant agriculture or health authority.
As of 2026-10-21, Bird Flu FYI’s database holds 18,149 outbreak records compiled from official sources, spanning 116 countries, of which 193 have a confirmation date in the last 30 days. These are counts of records in this database — not an official tally of outbreaks worldwide — and they change as sources publish, revise or withdraw reports. The database is refreshed once a day; open the map to explore records by location and animal type. For official figures, consult the source agencies listed on this page.
Bird Flu FYI shows confirmed H5N1 detections as published by official sources: the United States (USDA APHIS, which reports at state or county level), Europe (EFSA/ECDC), Australia (DAFF) and other countries (FAO EMPRES-i). A location appearing on the map means a detection was publicly confirmed there on the date shown; it does not mean the area is currently affected, and a location not appearing does not mean it is free of bird flu. Coverage depends on what each source publishes. Open the map and filter by region or animal type to see confirmed records, and confirm current status with the relevant authority.
Bird Flu FYI cannot tell you whether bird flu is present near you. It can only show detections that official sources have already publicly confirmed, which are often placed at an approximate point (a locality, county or country centre), can be days or weeks behind events, and never include unreported or unconfirmed cases. With that in mind, you can choose a location or allow location access on the map to see the nearest confirmed records, and optionally set free browser alerts for places you choose. Alerts are a convenience that depends on your browser and on when sources publish; they are not guaranteed to arrive and should not be relied on. If you keep birds or animals, or have a health concern, follow the guidance of your agriculture or health authority rather than this map.
Official sources have reported H5N1 detections in livestock. In particular, USDA APHIS has published confirmed detections in dairy cattle herds in the United States since 2024. Bird Flu FYI maps livestock detections as reported by those sources — filter the map to “Livestock” to see the records and their confirmation dates. This site does not assess whether the virus is currently spreading in any herd, region or industry; for herd status, testing requirements and official guidance, consult your agriculture authority (in the US, USDA APHIS).
H5N1 is a subtype of avian influenza A virus. Strains classified by animal-health authorities as highly pathogenic avian influenza (HPAI) are commonly called “bird flu”. According to the World Health Organization and the World Organisation for Animal Health, HPAI primarily affects wild birds and poultry, and H5N1 detections have also been reported in a range of mammals and in people. Health agencies monitor it closely. This is a general description only; for medical or public-health information refer to WHO, your national health authority, or a medical professional.
Outbreak data is compiled from official public sources and refreshed once a day; each page shows when it was last refreshed. Bird Flu FYI does not verify, correct or supplement the sources, and errors, delays, revisions or gaps in those sources will be reflected here. The sources report when an outbreak is confirmed, not when it ends, so Bird Flu FYI does not track official clearances: a record is shown as “recent” for a fixed display window after its confirmation date (roughly 8 weeks for poultry, 13 weeks for livestock, 30 days for other types). That window is a display convention, not an official status, and the real situation may differ either way. The data is provided for general awareness only, is not a substitute for official guidance, and must not be relied on for biosecurity, restocking, trade, travel, medical or health decisions.
Declaring an outbreak over is a formal decision made by the relevant agriculture or health authority under its own rules, which differ between countries and between animal types; wild-bird detections are often not formally “closed” at all. Bird Flu FYI does not track or display those decisions. It shows confirmed detections only and cannot tell you whether an outbreak is officially over, whether an area has been cleared, or whether movement restrictions apply. Always check your agriculture or health authority for current status.
