Yemen: Cholera numbers on decline /update 1

Event

As of March 13, almost 1.1 million suspected cholera cases had been reported in Yemen since late April 2017, accounting for 2266 associated deaths. However, according the World Health Organization (WHO), the number of reported cases of cholera has decreased in recent weeks, with fewer than 10,000 active suspected cases reported as of early March; in comparison, around 10,000 active suspected cases were reported in December 2017. Among the regions with the most suspected cases reported since April 2017 are those controlled by the Houthi rebels, notably including the provinces of Al-Hudaydah, Hajjah, Sana'a, Dhamar, Amran, as well as the district of Amanat Al-Asimah (city of Sana'a). Further suspected cases of cholera are expected to be reported in Yemen in the coming weeks; WHO officials expect a surge in cholera case numbers in April and August, corresponding to expected increased rainfall during the rainy seasons in the abovementioned most affected areas.

Context

Cholera is an infectious disease caused by the Vibrio cholerae bacterium that can induce acute diarrhea. The risk of death is greatest among people with compromised immune systems, such as malnourished children or those living with HIV. However, even among healthy adults, cholera can be fatal within a matter of hours. 

Sana'a and surrounding provinces are subject to two distinct rainy seasons, centered around April and August.

Advice

Individuals in or planning travel to Yemen are strongly advised to receive cholera vaccinations. It is also advised to stock up on food and bottled water, and conserve water as much as possible.

The security environment throughout the country remains complex, and due to poor security conditions, most Western governments strongly advise their citizens against all travel to Yemen. Travel to the country should only be considered with proper security protocols in place, and professional security advice and support should be sought prior to travel.
