The war-torn country of Yemen is being ravaged by a daunting new invader: a massive outbreak of cholera.

More than 100,000 cases have now been reported in the country, according to the World Health Organization.

The two-year conflict between the government and the rebelling Houthi group in the northern part of the country has meant that less than half of the country’s health facilities and infrastructure is fully operational. Health and sanitation workers have not been paid their salaries in eight months, according to accounts.

Some 14.5 million people do not have regular access to clean water and sanitation, the WHO added.

The latest outbreak has included 791 deaths as of this week. Children account for nearly half of the cholera cases throughout the country.

Health officials are still working to beat back the epidemic, which was first announced by the government in October 2016.

According to BBC reports, the greatest number of cases have been reported in the rebel-controlled capital of Sana’a. Those in control of that city declared a state of emergency last month.

Eliminating the densest clusters of the disease is crucial to turning the tide, said Nevio Zagaria, the head of the WHO office in Yemen.

“These cholera ‘hot spots’ are the source of much of the country’s cholera transmission,” said Zagaria. “Stamp out cholera in these places and we can slow the spread of the disease and save lives.

“At the same time, we’re continuing to support early and proper treatment for the sick and conducting prevention activities across the country,” the doctor added.

The latest outbreak has prompted a war-time response from the WHO and UNICEF. Disinfecting water tanker filling stations, chlorinated drinking water, teams to restore water treatment plants and water supply systems, and distribution of hygiene kits have all cumulatively improved conditions for about 3.5 million people, the agencies said.

Medical supplies were regularly and readily reaching the country prior to March 2015. Since that time, the vital materials have slowed to a third of the arrival rate.

Further funding is needed, they added.
