Catherine, aged 50, came to the hospital with classic malaria symptoms of malaise, anorexia, headache, body pain, and vomiting. She was treated with intravenous drugs and rehydration, and discharged in satisfactory condition within a few days. Sierra Leone has one of the highest burdens of malaria in the world, according to UNICEF. The country's entire population is at risk of the disease and it is one of Sierra Leone’s leading causes of death and illness. Malaria is the reason behind nearly four in ten hospital consultations countrywide. Through in-hospital treatment and village outreach, Mercy Hospital treats hundreds of children and adults for severe malaria infection every month.
