NIgeria: Cholera

maybe because the infrastructure for drinking water is lacking

this is from 3 years ago:

and this is from 9 years ago:

the movement of population from villages to the city outstrips the ability to provide services such as water.

a restricted article on the background:

Even if people can afford to pay the bills, the provision of urban services by state actors (or commissioned firms) is erratic and often not available. The daily infrastructure provision remains the responsibility of individuals and groups, mostly organised in complex yet fragile and changing networks. Drawing from the research on the existing, largely informal water supply in slum communities, this article argues for the recognition and pro-active implementation of hybrid approaches in the planning, implementation and administration of urban infrastructure. It calls for co-production and ‘hybrid water governance’.

here is another recent article:

the more recent articles blame global warming of course, but what is not mentioned: Corruption. How bad is corruption? So bad that it has a wikipedia page about it.Nigeria ranked 145th among the 180 countries in the Index, where the country ranked first is perceived to have the most honest public sector.

2021 BBC article.

Replacing aging infrastructure is often low priority even in the USA, but when aid money is easily diverted or shoddy work on the infrastructure is done, the result is disease. I cannot prove how much this contributes to the cholera epidemic, but in Harare and even parts of the Philippines, it was a major cause of cholera.
