SANAA, Yemen, Yemen has prepared emergency plans, to continue the fight against cholera, aimed at improving the sanitation system, providing clean water and raising public awareness about this epidemic, officials said.

The death toll from cholera climbed to 1,940, and the suspected cases to more than 463,000 on Sunday, said Abdulhakim Al-Kuhlani, spokesperson for the public health and population ministry, in Sanaa.

"We have a national emergency plan focused on improving epidemiological surveillance, providing fast response teams and necessary medicines, and opening treatment centres across the republic," Al-Kuhlani said.

Spokesperson for the health ministry, within the legitimate government in Aden, Mohammed Mustafa Yasin, said, their plan is focused on environmental sanitation.

"The efforts to contain cholera require cooperation among all sectors, like the health ministry, the cleanliness fund, civil society and media," Yasin elaborated. "We are also launching a house-to-house health education campaign."

Yemeni officials said, the number of suspected cases per day has slightly decreased in recent weeks, in some areas, thanks to quick and effective interventions.

"In Aden, we are now receiving tens of suspected cases a day. In the first months of the outbreak, we were receiving hundreds of suspected cases a day," said Yasin. "The good news remains that 99.6 percent of the suspected cases were cured."

Yemen is facing a triple threat of war, hunger and cholera, the UN warned.
