Cholera soars in Lake Chad Basin countries

Cholera has killed at least 1,200 people this year in the countries surrounding Lake Chad - Cameroon, Chad, Niger and Nigeria; the illness, linked primarily to poor sanitation and lack of potable water, has struck some 38,800 people in the region this year and continues to spread.

A good part of the rainy season lies ahead; while some epicentres reported cholera cases during the dry period, the rains generally cause spikes as water sources become contaminated.

The unique Lake Chad Basin is the centre of economic activity - commerce, fishing, farming - for some 11 million people, according to an August report by the UN Children's Fund (UNICEF). Population movements for social and commercial activity are constant between areas where sanitation is poor. All this contributes to the explosion of cholera once infection starts, according to aid agencies doing prevention work in the region.

That is why a regional strategy is critical, UNICEF says. "A cross-border, decentralized approach is necessary to protect each country's population and nip outbreaks in the bud," says François Bellet, UNICEF regional water and sanitation specialist for west and central Africa.

Development blow

Countless families depend on commerce, fishing and other activities in the region; at the same time cholera seriously undermines economic development, says the Chad government in an anti-cholera plan.

"Cholera hits families' revenue and brings recurrent health expenses - all of this deepens poverty and under-development."

In October 2010, health ministers of the four countries plus Benin signed the Abuja Commitment, calling for better collaboration to tackle cholera and other infectious diseases. The health ministers acknowledge that people have inadequate access to clean water and proper sanitation and that cross-border coordination mechanisms are lacking, with no formal way for health districts to share disease surveillance data.

Last year, the Lake Chad Basin region reported 58,000 cases of cholera, with 2,300 deaths, according to UNICEF - the most serious outbreak since 1991. Here is a tally of how many people have been affected this year:

Cameroon: As of 22 August, 14,730 cases; 554 deaths. Lethality rate 3.76 percent.

Chad: As of 22 August, 10,314 cases; 314 deaths. Lethality rate 3.1 percent.

Niger: As of 8 August, 976 cases; 25 deaths. Lethality rate 2.5 percent.

Nigeria: As of 1 August, 12,840 cases; 318 deaths. Lethality rate 2.5 percent.

We uncovered the sex abuse scandal that rocked the WHO, but there’s more to do

We just covered a report that says the World Health Organization failed to prevent and tackle widespread sexual abuse during the Ebola response in Congo.

Our investigation with the Thomson Reuters Foundation triggered this probe, demonstrating the impact our journalism can have. 

But this won’t be the last case of aid worker sex abuse. This also won’t be the last time the aid sector has to ask itself difficult questions about why justice for victims of sexual abuse and exploitation has been sorely lacking. 

We’re already working on our next investigation, but reporting like this takes months, sometimes years, and can’t be done alone. 

The support of our readers and donors helps keep our journalism free and accessible for all. Donations mean we can keep holding power in the aid sector accountable, and do more of this.
