Purpose
Background:
- Malaria is a leading cause of morbidity and mortality in Uganda, accounting for more than a quarter of all outpatient visits at health facilities, 20 percent of hospital admissions, and about 10 percent of inpatient deaths. Children under 10 years of age, pregnant women, and HIV-infected individuals bear the greatest burden of disease. To provide baseline information for future malaria vaccine research, development, and testing, researchers are interested in collecting malaria infection data from the Rakai district in southern Uganda.
Objectives:
- To assess the epidemiology of malaria infection among children aged 6 months to less than 10 years and adults living in same households with children in Rakai district, Uganda.
Eligibility:
- Children between 6 months and 10 years of age, as well as their primary caregiver and an additional randomly selected adolescent or adult resident of the household, from the Rakai district of Uganda.
Design:
- Participants will have monthly household visits for a 1-year surveillance period.
- Each visit will include a structured interview/questionnaire of the primary caregiver or legal guardian of the child and clinical and laboratory assessments of each child, the primary caregiver, and the additional adolescent or adult resident of the household. The questionnaire will ask about malaria treatment and prevention measures.
- Children will provide a blood sample for testing. Individuals (children or adults) who are diagnosed with malaria or anemia during the course of the study will be recommended for treatment.
- Researchers will also track usage of the district health clinic and hospital services to link medical records for study participants.

Malaria is a leading cause of morbidity and mortality in Uganda, accounting for 25-40 percent of all outpatient visits at health facilities, 20 percent of hospital admissions, and 9-14 percent of inpatient deaths. Malaria is meso- to holoendemic in Rakai, southwestern Uganda and children under 10 years, pregnant women and HIVinfected individuals bear the greatest burden of disease. Substantial progress has been made in malaria vaccine development and vaccine trials will be conducted over the coming years. The design of these trials will be contingent on understanding the epidemiology of malaria and disease burden in different epidemic settings.
This study will determine the epidemiology of malaria infection in children and adolescents/adults by conducting surveillance in 320 households selected from two of the 10 clusters under the Rakai Community Cohort Study (RCCS). Monthly visits will be made to randomly selected households during a one year surveillance period. Visit procedures include: structured interview/questionnaire of the primary care giver or legal guardian of the child; clinical and laboratory assessment of each child aged 6 months up to 10 years and the primary care giver; and clinical and laboratory assessment of one additional randomly selected adolescent/adult resident of the household. The study team will track usage of health clinic or hospital services within the district in order to link medical records for study participants. This community-based surveillance study will be linked to a separate facility-based surveillance study in health clinics/hospitals servicing the selected communities. This study will enhance the investigators' understanding of the epidemiology of pediatric and adult malaria infection in Rakai district in preparation for future malaria vaccine trials. Investigators will be able to estimate the incidence of uncomplicated and severe malaria in children and adults. This protocol will also investigate the prevalence and association of sickle cell trait, xlinked glucose-6-phosphatase dehydrogenase deficiency and hemoglobinopathies (Hemoglobin C) and their associations with severe malaria among children and adults.
