The main cause of death in Nigeria is lower respiratory infections.
Leading Causes of Mortality in Nigeria
According to data from the World Health Organization (WHO), lower respiratory infections account for the highest number of deaths in Nigeria, significantly impacting public health across the nation. These infections include conditions such as pneumonia and bronchitis, which can be particularly severe in populations with limited access to adequate healthcare and sanitation.
Here's a breakdown of the leading causes of death in Nigeria based on available data:
| Cause of Death | Burden (Deaths per 100,000) |
|---|---|
| Lower respiratory infections | 95.9 |
| Malaria | 84.8 |
| Diarrhoeal diseases | 75.7 |
| Tuberculosis | 59.5 |
| Birth asphyxia and birth trauma | 37.1 |

As evident from the table, lower respiratory infections represent the most significant mortality burden, indicating a critical area for public health intervention.
Understanding Lower Respiratory Infections
Lower respiratory infections are acute infections of the lungs and airways, often caused by viruses or bacteria. Pneumonia is a common and severe form of lower respiratory infection, especially dangerous for young children, the elderly, and individuals with compromised immune systems. In settings like Nigeria, factors contributing to their high prevalence and fatality rates can include:
- Environmental factors: Exposure to indoor air pollution from cooking with solid fuels.
- Nutritional status: Malnutrition can weaken the immune system, making individuals more susceptible.
- Access to healthcare: Limited access to timely diagnosis, antibiotics, and oxygen therapy.
- Vaccination rates: Insufficient uptake of vaccines against common pathogens like Streptococcus pneumoniae (pneumococcus) and Haemophilus influenzae type b (Hib).
Broader Public Health Challenges
While lower respiratory infections are the leading cause, Nigeria faces a complex array of public health challenges, with other infectious diseases and birth-related complications also contributing significantly to mortality:
- Malaria: Remains a major killer, particularly among children under five, despite ongoing control efforts.
- Diarrhoeal Diseases: Often linked to poor sanitation, contaminated water sources, and inadequate hygiene practices.
- Tuberculosis (TB): A persistent infectious disease, often exacerbated by co-infection with HIV and drug-resistant strains.
- Birth Asphyxia and Birth Trauma: High rates reflect challenges in maternal and newborn care, including access to skilled birth attendants and emergency obstetric services.
Addressing the Mortality Burden
Tackling these leading causes of death requires a multi-faceted approach focusing on prevention, early diagnosis, and improved access to quality healthcare. Key strategies include:
- Strengthening Immunization Programs: Expanding coverage for vaccines against pneumonia-causing bacteria (e.g., PCV) and other preventable diseases.
- Improving Water, Sanitation, and Hygiene (WASH): Investing in safe drinking water sources, sanitation facilities, and promoting handwashing to reduce diarrhoeal diseases.
- Enhancing Malaria Control: Distributing insecticide-treated bed nets, improving access to antimalarial drugs, and implementing effective vector control measures.
- Boosting Maternal and Child Health Services: Ensuring access to skilled birth attendants, emergency obstetric care, and postnatal care to reduce birth-related complications.
- Combating Tuberculosis: Strengthening TB diagnostic and treatment services, including efforts to address drug-resistant forms and improve case detection.
- Addressing Air Pollution: Promoting cleaner cooking fuels and technologies to reduce exposure to indoor air pollutants.
These interventions are crucial for reducing premature deaths and improving public health outcomes across Nigeria.
