Nigeria, the most populous nation in Africa, deals with a number of health issues that affect millions of people annually. Many prevalent diseases still exist despite tremendous advancements in healthcare because of things like socioeconomic status, climate, public health knowledge gaps, and restricted access to care. Improving the health of Nigerians across the country requires an understanding of these conditions and the implementation of preventative actions.

1. Malaria

In Nigeria, malaria continues to be one of the most common and fatal illnesses. It is spread by the female Anopheles mosquito and manifests as fever, chills, and headaches. In extreme situations, it can result in organ failure and even death. The majority of malaria cases and fatalities worldwide occur in Nigeria. In order to prevent mosquito bites, people should sleep under insecticide-treated nets, spray insecticides inside their homes to kill mosquitoes, remove standing water where mosquitoes grow, and make sure that antimalarial medications are administered promptly.

2. AIDS/HIV

In Nigeria, the infectious diseases HIV and AIDS continue to pose a serious threat to public health. Because the illness impairs immunity, people are more vulnerable to opportunistic infections. Safe sexual practices, such as using condoms frequently and limiting the number of sexual partners, are examples of preventive methods. In addition to early HIV testing and counseling, education and awareness on prevention and transmission are crucial. Antiretroviral medications are also used during pregnancy to stop the spread of the virus from mother to child.

3. TB (tuberculosis)

A bacterial infection that mostly affects the lungs, tuberculosis is spread by airborne droplets released by infected people when they cough or sneeze. One of the nations with a high TB burden is Nigeria. The Bacillus Calmette–Guérin (BCG) vaccine for children, early detection and completion of the entire course of TB medication, maintaining well-ventilated living areas to minimize transmission, and avoiding close contact with active TB patients are all examples of prevention.

4. Diseases of the diarrhea

In Nigeria, diarrheal illnesses—which are frequently brought on by tainted food, water, or inadequate sanitation—play a major role in child mortality. Outbreaks of cholera are particularly frequent during the rainy season. Access to clean drinking water that has been boiled or treated, good sanitation habits like using sanitary toilets and disposing of waste, frequent hand washing with soap, and safe food handling procedures like preparing and storing food properly are all necessary to prevent these infections.

5. High blood pressure, or hypertension

Nigeria is seeing a rise in the prevalence of hypertension as a result of dietary changes, urbanization, and lifestyle changes. High blood pressure, which is frequently asymptomatic in its early stages, can result in major consequences like heart disease and stroke. A healthy diet that includes less salt and more fruits, vegetables, and whole grains, regular exercise, abstaining from tobacco and excessive alcohol, and routine blood pressure checks to guarantee early diagnosis and medication compliance are all part of prevention.

6. Infections of the respiratory system

Pneumonia and bronchitis are common acute respiratory illnesses, especially in children and the elderly. Smoking, inadequate ventilation, and pollution are all contributing issues. Immunization against influenza and pneumococcal illness, limiting tobacco smoke exposure, maintaining excellent hygiene (such as covering one’s mouth when coughing and frequently washing one’s hands), and enhancing living conditions to lower indoor air pollution are all ways to prevent respiratory infections.

7. Undernourishment

Many Nigerians, particularly children under five, suffer from malnutrition, which includes both undernutrition and overnutrition. It slows down cognitive and physical growth and impairs the immune system. A balanced diet full of proteins, vitamins, and minerals, exclusive breastfeeding for the first six months of life, training caregivers on appropriate child feeding techniques, and the provision of essential micronutrient supplements like vitamin A and iron are all examples of preventive interventions.

Conclusion

Nigerian health issues are closely linked to both infrastructure constraints and socioeconomic variables. Nonetheless, the most economical method of lowering the burden of disease is still prevention. To improve health outcomes nationwide, public health education, access to sanitary facilities and clean water, immunizations, and lifestyle modifications are essential. To effectively implement these preventative methods and improve healthcare accessible for a healthier Nigeria, governments, non-governmental organizations, and communities must continue to collaborate.
