Nigeria battles its largest Lassa fever outbreak on record

Update on yellow fever in Nigeria

21 December 2017 - Reports of yellow fever cases throughout Nigeria are escalating concerns about the risk of large, costly, and difficult-to-control outbreaks in urban areas requiring huge supplies of life-saving vaccines and increasing the potential for large-scale national and worldwide spread. Fears that the situation in globally connected Nigeria could soon mirror the massive 2016 urban outbreak in Angola, during which cases were exported to neighboring Democratic Republic of the Congo and as far as China, are raising urgent calls for quick containment.

Epidemiological Bulletin

In north-eastern Nigeria, some 5.2 million people face food insecurity. When people are malnourished, preventable diseases like cholera and malaria can turn deadly. The biggest killer is often malaria. WHO and health sector partners are working with the Nigerian Government to support malaria control efforts, such as distribution of bed nets and providing malaria drugs. However, efforts will fall short without more funds, especially for health sector partners. More than 10 000 people could die from preventable deaths due to malaria in the coming months.



Cholera is an acute intestinal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae.


Malaria is caused by parasites that are transmitted to people through the bites of infected female mosquitoes.
