Insights
High malaria parasite density, lack of mosquito bite prevention, and poverty significantly increase severe malaria risk in Nigerian children under five. Understanding these factors is crucial for effective malaria control.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Malaria disproportionately affects sub-Saharan Africa, with children under five being the most vulnerable population.
- In Nigeria, malaria contributes significantly to infant (25%) and childhood (30%) mortality.
- Severe malaria poses a substantial public health challenge in endemic regions.
Purpose of the Study:
- To identify factors associated with severe malaria in children under five presenting to a hospital in Ile-Ife, Nigeria.
- To determine the prevalence of severe malaria and associated risk factors within this vulnerable demographic.
- To inform targeted interventions for malaria control in Nigeria.
Main Methods:
- A study was conducted involving 176 children under five diagnosed with malaria at the Seventh Day Adventist Hospital, Ile-Ife, from May to September 2005.
- Clinical and parasitological criteria were used for malaria diagnosis.
- Seventeen variables were examined to identify independent risk factors for severe malaria.
Main Results:
- The proportion of children with severe malaria was 17%, with a case-fatality rate of 3.5%.
- High malaria parasite density was a significant risk factor.
- Non-use of mosquito-bite preventive measures and poverty were independently associated with an increased risk of severe malaria.
Conclusions:
- High parasite density, lack of protective measures against mosquito bites, and poverty are key independent risk factors for severe malaria in Nigerian children under five.
- Accurate epidemiological understanding is vital for advancing malaria control efforts.
- Targeted interventions addressing these factors are necessary to reduce the burden of severe malaria.
Abstract:
Over 90% of the burden of malaria occurs in sub-Saharan Africa. Children, especially under-fives, are the most vulnerable. In Nigeria, Africa's most populous nation, it accounts for 25 and 30% of infant and childhood deaths, respectively. One hundred and seventy-six children who fulfilled clinical and parasitological criteria for the diagnosis of malaria, 26.4% of all under-fives, who presented to the Seventh Day Adventist Hospital in Ile-Ife during the months of May to September 2005 were studied to identify the factors that were associated with severe malaria in the target population. The proportion of children with severe malaria in the study was 17%, while the case-fatality rate was 3.5%. Of the 17 variables examined, high malaria parasite density, non-use of mosquito-bite preventive measures and poverty remained independently and significantly associated with an increased risk for severe malaria. Progress in stemming the burden of malaria depends on accurate knowledge and understanding of the epidemiology and control of the disease in the affected populations.
