Outbreak Map
A newsroom-curated October 2026 roundup of the major disease outbreaks our editors are tracking around the world — grouped by region, with plain-language status lines and links to official sources.
Africa
The continent carries the heaviest current outbreak burden, from mpox to cholera.
Mpox
Ongoing transmission continues across the DRC and neighboring central African countries. Health agencies are watching cross-border spread, vaccine access, and protection for health workers.
Cholera
Cholera outbreaks remain active in several countries. Conflict, displacement, and strained water and sanitation systems are complicating containment and vaccination drives.
Ebola / Marburg risk zones
No large-scale outbreak was reported at the time of compilation. Known risk zones remain under routine surveillance, with rapid-response teams and contact-tracing capacity kept on standby.
Asia
Border health controls and avian flu circulation are the stories to watch.
Plague
October 2026: Mongolia and Russia tightened health controls at their shared border amid a plague scare. Plague is endemic in parts of the region's rodent populations; authorities stepped up screening and public guidance.

H5N1 avian influenza
H5N1 continues to circulate in wild birds and poultry. Sporadic spillover into mammals is being watched closely; human cases remain rare and are investigated case by case.
Americas
A vaccine-preventable disease is making a comeback.
Measles resurgence
Measles cases are climbing on the back of vaccination gaps. Health agencies are urging catch-up shots for children and checking immunization status before travel.
Global
Threats that cross borders by definition.
H5N1 avian influenza
The global spread of H5N1 in birds and mammals continues. Human cases are monitored individually; agencies stress avoiding contact with sick or dead wild birds and animals.
Measles resurgence
A worldwide measles resurgence driven by falling immunization coverage, with outbreaks reported on multiple continents. Two doses of measles vaccine remain the key defense.
What to watch / prevention
- Stay current on routine vaccinations — including measles and seasonal flu shots; check immunization status before international travel.
- Practice basic hygiene — handwashing and safe food and water are the first line of defense against cholera and other waterborne illness.
- Check travel advisories — review WHO and CDC guidance before trips, especially to regions with active outbreaks or border health controls.
- Avoid sick or dead wild animals and birds — report die-offs to local authorities rather than handling them.
- Seek care early — fever, rash, or severe diarrhea after travel or animal contact warrants prompt medical attention; mention your travel history.
- Follow official guidance — rely on WHO, CDC, and local health authorities rather than rumors during a scare.
