Disease outbreaks reported by WHO

The World Health Organization's Disease Outbreak News, newest first. This is an index of what WHO published, with a link to each bulletin — not a copy of it.

Not every outbreak here followed a disaster. WHO reports every outbreak within its remit, and many have no connection to a flood or an earthquake at all. Working out which ones did cannot be done from a headline, so this page does not guess — it shows what WHO published and links to their own assessment.

A dash in the country column means the headline named no country this site holds a page for — a multi-country event, or an update to an earlier bulletin. The country is read from WHO's own title rather than guessed.

Why a disaster site tracks outbreaks

Because the second disaster is often the disease. Standing floodwater breeds the mosquitoes that carry malaria and dengue. Displacement puts people into camps sharing water and sanitation. Damaged treatment plants put sewage into drinking supplies, and cholera follows. Pakistan's 2022 monsoon floods were followed by a malaria surge and a cholera emergency across the worst-hit districts of Sindh — the same districts, the same people, weeks later.

Somebody reading about a flood on this site is usually asking what happens next. This is part of the answer, which is why it sits here rather than being left to a health site the reader would have to go and find.

What this page is not

Not medical advice
Nothing here tells you what to do about an illness. WHO's own bulletin carries their risk assessment and advice, and every row above links straight to it. For anything personal, a doctor and your national health service are the answer, not a website.
Not graded by us
WHO does not publish a severity level for these bulletins and we do not invent one. You will not find a red badge on this page; every other coloured badge on this site means a hazard level that an agency issued, and putting one here would mean something that is not true.
Not on the map
An outbreak is not a thing that happened at a coordinate on a date, so it never becomes a marker or an alert. The same rule keeps geomagnetic storms off the map: an event with no location cannot honestly be given one.
