Cholera Vaccinations Found Very Effective in Niger

The World Health Organization (WHO) Africa today reported vaccinations contributed to the fight against the cholera epidemic that affected seven regions of Niger, causing 5,591 infections and 166 deaths, with a case-fatality rate of 3%.

Vaccination coverage of 95%, combined with good patient management and hygiene and sanitation awareness, led to a significant decrease in the number of new cases until the epidemic was recently declared over.

An essential intervention empowered health authorities to rapidly deploy the cholera vaccine in the four most affected regions (Dosso, Maradi, Tahoua, and Zinder) and administer it to nearly 1.9 million people.

The first intervention was to deploy the vaccine as close to the population as possible instead of holding vaccination sessions at fixed locations.

"The adoption of the door-to-door strategy avoided massive gatherings, which would have increased close contact between patients and populations at risk of contracting the disease," explained Dr. Blanche Anya, WHO Resident Representative in Niger, in a WHO press release issued on April 29, 2020.

"This strategy also improved vaccination delivery to communities in hard-to-reach locations.”

Cholera is not the only disease Niger has confronted in 2022.

The U.S. CDC has recently issued Travel Notices for Niger focused on COVID-19 and polio.
