cholera in yemen

One child infected every 35 seconds in Yemen cholera crisis

Over the past six weeks, more than 200,000 suspected cholera cases have been reported. To put this in perspective, there were only 172,000 cases reported globally to the World Health Organization for all of 2015. To be fair, many cholera cases go unreported each year, but by any standard the current outbreak in Yemen is huge.

"And geographically it is expanding," says Mohamed El Montassir Hussein, the country director for the International Rescue Committee, based in the capital Sanaa. "It's not a small area. It's almost the whole country." Cases have now been reported from 20 of the country's 22 provincial governments. The IRC, along with other international aid groups and WHO, is attempting to set up treatment centers for the growing number of people suffering from the violent form of diarrhea. Left untreated, cholera can cause victims to lose so much fluid so quickly that it can kill them within a matter of days or even hours.

internally displaced persons (IDPs)

10.4% of the total population of Yemen has experienced the shock of displacement

As of 01 April 2017, the TFPM has identified, 1,988,946 internally displaced persons (IDPs) (331,491 households) who have been displaced due to conflict since March 2015, dispersed across 21 governorates. For the same period, the TFPM has identified 900,258 returnees (150,043 households), across 19 governorates.
As a result, 10.4% of the total population of Yemen has experienced the shock of displacement due to conflict in the last 24 months

water

10 million people are at risk of losing access to water

Ravaged by war, climate change, water shortage, and government mismanagement, Yemen is already in many ways a failed state. It will require immense assistance just to provide for its people’s basic needs in years to come.
Last month, the UN asked for an unprecedented $2.1 billion to help stave off the country’s “worst humanitarian crisis” ever. With foreign aid budgets being slashed globally, it is unclear if this money will ever arrive.
