Yemen cholera death toll rises – number of infections drop, says WHO

The number of people who have died in a cholera epidemic affecting Yemen has risen to at least 471, according to the World Health Organization (WHO).

But the latest WHO bulletin, covering the period from 27 April, said that there was a "significant decrease" in the daily average number of cases recorded in the week up to 27 May compared to the previous seven-day period.

The epidemic began in October and grew until December.

It then dwindled but was never brought fully under control, and a new surge in cases began in April.

Yemen has been hit hard by civil war, with 19 million of its 28 million people needing humanitarian aid and many of them on the brink of famine.

Fewer than half of the country's health facilities are fully functional.

More than 50,000 cases

The WHO said yesterday that the average daily number of cases recorded between 21-27 May was 2,529 - down from 3,025 in the previous seven days.

The bulletin said that the total number of suspected cases stood at 51,832.

Caused by ingesting bacteria from water or food contaminated with faeces, cholera usually manifests itself with sudden acute diarrhoea and can kill within hours, although three-quarters of infected people show no symptoms.

The short incubation period means outbreaks can spread with speed, especially in places without safe water and proper sanitation, according to the WHO.
