Health guides

What the condition is, the symptoms that matter, when it stops being something to watch and becomes something to see someone about, and what the treatment costs. Written for a patient, not for a search engine.

Every guide here is reviewed by Dr Debo Odulana, Founder and Chief Executive, Mezo. Last reviewed 8 October 2026. These pages are general information, not a diagnosis.

Malaria

Malaria is a life-threatening disease caused by parasites transmitted through the bites of infected mosquitoes. Nigeria accounts for approximately 27% of global malaria cases. Early diagnosis and treatment are critical — most malaria deaths occur due to delayed care.

Typhoid Fever

Typhoid fever is a bacterial infection caused by Salmonella typhi, spread through contaminated food and water. Nigeria has one of the highest typhoid burdens globally. Without treatment, typhoid can be life-threatening, but it is highly treatable with antibiotics when caught early.

Internal Medicine

Sickle Cell Disease

Sickle cell disease (SCD) is a genetic blood disorder particularly prevalent in Nigeria: the country has the highest burden of SCD in the world, with an estimated 150,000 babies born with the condition each year. It causes red blood cells to become rigid and sickle-shaped, leading to pain crises, organ damage, and shortened life expectancy.

Asthma
