Yemen cholera epidemic: Cases exceed 500,000 in four months

The number of suspected cases of cholera resulting from an epidemic in war-torn Yemen has reached 500,000, the World Health Organization (WHO) says.

At least 1,975 people have died since the waterborne disease began to spread rapidly at the end of April.

The WHO said the overall caseload had declined since July, but that 5,000 people a day were still being infected.

The disease spread due to deteriorating hygiene and sanitation conditions and disruptions to the water supply.

More than 14 million people are cut off from regular access to clean water and sanitation in Yemen, and waste collection has ceased in major cities.

Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholera.

Most of those infected will have no or mild symptoms but, in severe cases, the disease can kill within hours if left untreated.

More than a quarter of those who have died and 41% of those who have been infected have been children, according to the UN Office for the Co-ordination of Humanitarian Affairs.

Yemen's health service has struggled to cope with the cholera epidemic - currently the largest in the world - with more than half of all medical facilities closed due to damage sustained during more than two years of conflict between pro-government forces and the rebel Houthi movement.
