For example, the National Programme on Immunisation shows a continuing and dramatic decline in the incidence of fatal childhood diseases in Nigeria, including tetanus, poliomyelitis, diptheria, measles, tuberculosis, yellow fever, and cerebrospinal meningitis, which have been responsible for high infant mortality in the country.
Ainsi, le programme national de vaccination fait état d'une baisse continue et spectaculaire de l'incidence de maladies infantiles mortelles au Nigeria, comme le tétanos, la poliomyélite, la diphtérie, la rougeole, la tuberculose, la fièvre jaune et la méningite cérébro-spinale, auparavant responsables de fortes mortalités infantiles dans ce pays.
