Claim: Nigeria bears 50% of the global sickle cell burden

Q1: What percentage of the global sickle cell burden is borne by Nigeria?
A1: Frequencies of the carrier state determine the prevalence of sickle-cell anaemia at birth. For
example, in Nigeria, by far the most populous country in the subregion, 24% of the population are
carriers of the mutant gene and the prevalence of sickle-cell anaemia is about 20 per 1000 births. This
means that in Nigeria alone, about 150 000 children are born annually with sickle-cell anaemia.

justification: The answers show that currently they bear 20% of sickle cell carriers so the claim is refuted.
