note: on 7 October 2019, the Centers for Disease Control and Prevention issued a Travel Health Notice for a Yellow Fever outbreak in Nigeria; a large, ongoing outbreak of yellow fever in Nigeria began in September 2017; the outbreak is now spread throughout the country with the Nigerian Ministry of Health reporting cases of the disease in all 36 states and the Federal Capital Territory; the CDC recommends travelers going to Nigeria should receive vaccination against yellow fever at least 10 days before travel and should take steps to prevent mosquito bites while there; those never vaccinated against yellow fever should avoid travel to Nigeria during the outbreak
note: widespread ongoing transmission of a respiratory illness caused by the novel coronavirus (COVID-19) is occurring throughout Nigeria; as of 19 July 2021, Nigeria has reported a total of 169,678 cases of COVID-19 or 82.31 cumulative cases of COVID-19 per 100,000 population with 1.03 cumulative death per 100,000 population; as of 19 July 2021, 1.23% of the population has received at least one dose of COVID-19 vaccine
Food insecuritywidespread lack of access: due to civil insecurity - about 1.78 million people were projected to be in "Crisis" and above in the June-August 2021 period due to persistent insecurity in the Lac and Tibesti regions, which continues to disrupt livelihood activities and to cause population displacements; about 336,124 people were displaced due to insecurity in Lake Chad Region; COVID-19 pandemic containment measures continue to slow down the national economy, reducing employment opportunities; this downturn has contributed to a weakening of the purchasing power of poor vulnerable households, limiting their access to food (2021)widespread lack of access: due to persistent civil conflict in the northern areas - according to the latest analysis, about 12.8 million people are assessed to be in need of humanitarian assistance in the June-August 2021 period as a result of worsening conflict that is driving new population displacements; over 2.8 million people are estimated to be internally displaced in northeastern states of Adamawa, Borno and Yobe, due to communal clashes in northwestern/northcentral zones and natural disasters; the areas inaccessible to humanitarian interventions are facing the worst food insecurity conditions (2021)

Demographic profile

Despite the start of oil production in 2003, 40% of Chad's population lives below the poverty line. The population will continue to grow rapidly because of the country's very high fertility rate and large youth cohort - more than 65% of the populace is under the age of 25 - although the mortality rate is high and life expectancy is low. Chad has the world's third highest maternal mortality rate. Among the primary risk factors are poverty, anemia, rural habitation, high fertility, poor education, and a lack of access to family planning and obstetric care. Impoverished, uneducated adolescents living in rural areas are most affected. To improve women's reproductive health and reduce fertility, Chad will need to increase women's educational attainment, job participation, and knowledge of and access to family planning. Only about a quarter of women are literate, less than 5% use contraceptives, and more than 40% undergo genital cutting.

As of October 2017, more than 320,000 refugees from Sudan and more than 75,000 from the Central African Republic strain Chad's limited resources and create tensions in host communities. Thousands of new refugees fled to Chad in 2013 to escape worsening violence in the Darfur region of Sudan. The large refugee populations are hesitant to return to their home countries because of continued instability. Chad was relatively stable in 2012 in comparison to other states in the region, but past fighting between government forces and opposition groups and inter-communal violence have left nearly 60,000 of its citizens displaced in the eastern part of the country.

Nigeria's population is projected to grow from more than 186 million people in 2016 to 392 million in 2050, becoming the world's fourth most populous country. Nigeria's sustained high population growth rate will continue for the foreseeable future because of population momentum and its high birth rate. Abuja has not successfully implemented family planning programs to reduce and space births because of a lack of political will, government financing, and the availability and affordability of services and products, as well as a cultural preference for large families. Increased educational attainment, especially among women, and improvements in health care are needed to encourage and to better enable parents to opt for smaller families.

Nigeria needs to harness the potential of its burgeoning youth population in order to boost economic development, reduce widespread poverty, and channel large numbers of unemployed youth into productive activities and away from ongoing religious and ethnic violence. While most movement of Nigerians is internal, significant emigration regionally and to the West provides an outlet for Nigerians looking for economic opportunities, seeking asylum, and increasingly pursuing higher education. Immigration largely of West Africans continues to be insufficient to offset emigration and the loss of highly skilled workers. Nigeria also is a major source, transit, and destination country for forced labor and sex trafficking.
