Respiratory infections, such as pneumonia and tuberculosis, are a leading cause of illness and death in Nigeria, particularly among children under five years old and adults living with HIV/AIDS.

Respiratory tract infections (RTIs) are infections of parts of the body involved in breathing, such as the sinuses, throat, airways, or lungs. Four of the most common types of respiratory infections are COVID-19, the flu, pneumococcal disease, and colds.

Eucalyptus oil, from the leaves of the eucalyptus tree, has been traditionally used to treat respiratory infections and coughs. Ginger and garlic are also commonly used to alleviate symptoms of respiratory infections.
