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 insecuritysevere localized food insecurity: due to civil insecurity and population displacements - according to a March 2021 analysis, about 1.9 million people (7 percent of the total population) were projected to be severely food insecure in the June-August 2021 period; this mainly results from the effects of Boko Haram incursions in the Far North Region, the socio-political unrest in the Northwest and Southwest regions and COVID-19 related economic shocks, which disrupted trade flows and agricultural practices, deteriorated livelihoods and displaced people (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

Cameroon has a large youth population, with more than 60% of the populace under the age of 25. Fertility is falling but remains at a high level, especially among poor, rural, and uneducated women, in part because of inadequate access to contraception. Life expectancy remains low at about 55 years due to the prevalence of HIV and AIDs and an elevated maternal mortality rate, which has remained high since 1990. Cameroon, particularly the northern region, is vulnerable to food insecurity largely because of government mismanagement, corruption, high production costs, inadequate infrastructure, and natural disasters. Despite economic growth in some regions, poverty is on the rise, and is most prevalent in rural areas, which are especially affected by a shortage of jobs, declining incomes, poor school and health care infrastructure, and a lack of clean water and sanitation. Underinvestment in social safety nets and ineffective public financial management also contribute to Cameroon's high rate of poverty.  The activities of Boko Haram, other armed groups, and counterinsurgency operations have worsened food insecurity in the Far North region.  

International migration has been driven by unemployment (including fewer government jobs), poverty, the search for educational opportunities, and corruption. The US and Europe are preferred destinations, but, with tighter immigration restrictions in these countries, young Cameroonians are increasingly turning to neighboring states, such as Gabon and Nigeria, South Africa, other parts of Africa, and the Near and Far East. Cameroon's limited resources make it dependent on UN support to host more than 420,000 refugees and asylum seekers as of September 2020. These refugees and asylum seekers are primarily from the Central African Republic and Nigeria.  Internal and external displacement have grown dramatically in recent years.  Boko Haram's attacks and counterattacks by government forces in the Far North since 2014 have increased the number of internally displaced people.  Armed conflict between separatists and Cameroon's military in the the Northwest and Southwest since 2016 have displaced hundreds of thousands of the country's Anglophone minority.

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.
