This “Giant of Africa” turns out with a poor healthcare system, the fifth worst in the world. Its WHO score is 0.176/1. Nigeria is a federal republic comprised of 36 states. It’s located in West Africa between Benin to the west and Chad to the east. Nigeria is the most populated country in Africa with more than 174 million residents. The average life expectancy in the country, around 52.3 years, has been severely affected by the drastic income inequality prevailing in the country. Nigeria suffers from a continual mass exodus of nurses, doctors and other health practitioners who leave looking for better opportunities abroad. Each medically trained individual represents an investment by the government, which then suffers a net loss when the individual chooses to leave the country. Infant mortality is also an issue with about 20% of children dying before the age of five.click on this link to see the six worst countries in the World for Healthcare.
