More than half a million people in Yemen have been infected with cholera since the epidemic began four months ago and 1,975 people have died, the World Health Organisation (WHO) says.
Each day there are more than 5,000 new cases of the waterborne disease, which causes acute diarrhoea and dehydration, in the country where the health system has collapsed after more than two years of war, it said.
"The total number of suspected cholera cases in Yemen this year hit the half a million mark on Sunday, and nearly 2,000 people have died since the outbreak began to spread rapidly at the end of April," the WHO said in a statement on Monday.
"The spread of cholera has slowed significantly in some areas compared to peak levels but the disease is still spreading fast in more recently affected districts, which are recording large numbers of cases," it said, reporting a total of 503,484 cases.
The disease, spread by ingestion of food or water tainted with human faeces, can kill within hours if untreated. It has been largely eradicated in developed countries equipped with sanitation systems and water treatment.
But Yemen's devastating civil war, pitting a Saudi-led military coalition against the Iran-backed armed Houthi group, and economic collapse has made it extremely difficult to deal with catastrophes such as cholera and mass hunger.
Millions of Yemenis remain cut off from clean water and waste collection has ceased in major cities, the WHO added.
