Study type | Observational |
Approximately 4,000 people will participate per year. The study population will include
females and males over 5 years of age who live in filariasis and onchocerciasis endemic
areas. Subject selection will not be based on health status.
Two sites will be studied, and each study will last for 4 years. Participants will be studied
only once in cross-sectional surveys. Some subjects may be included in more than one annual
population survey, but this is not a longitudinal study.
Investigators will compare annual and semiannual mass drug administration (MDA) for lymphatic
filariasis and onchocerciasis, and investigators will compare the impact of these MDA
schedules on soil transmitted helminth infections. MDA will be administered by others
(Ivorian Ministry of Health).
The investigators will test the hypothesis that semiannual mass drug administration (MDA) is
superior to annual MDA for elimination of lymphatic filariasis, onchocerciasis and for
control of soil transmitted helminth (STH) infections.
1. Compare the relative impact and cost effectiveness of annual vs. twice yearly mass drug
administration (MDA) for elimination of lymphatic filariasis (LF) in these populations.
2. Compare the relative impact and cost effectiveness of annual vs. twice yearly mass drug
administration (MDA) for elimination of onchocerciasis in these populations.
3. Study the impact of annual vs. semiannual MDA on soil transmitted helminth (STH)
infection in these populations.

Primary | Microfilaria prevalence based on results of microscopic examination of blood smears and skin snips. | From annual population based surveys, the prevalence of microfilaremia (filarial parasites in the blood or skin snips) will be assessed by microscopic examination of slides with thick blood smears and skin snips. Test results for individuals are either positive or negative. The unit for prevalence studies is the percentage (%) of individuals with positive tests. | 4 years | |
Secondary | Prevalence of filarial antigenemia in blood and intensity of filarial and intestinal worm infections based on results of microscopy. | Secondary outcomes for the study include prevalence of filarial antigenemia (detected with the Alere Filariasis Strip test) and prevalence of worm eggs in stool detected by the Kato-Katz test. Both of these outcomes are qualitative with no units of measure (positive or negative). Other secondary outcome measures will be intensity of infection by counting microfilaria (Mf) in blood (Mf per ml of blood) and counting Mf in skin (Mf per milligram) and by counting worm eggs (eggs per gram of stool, assessed separately for each parasite species). All of these quantitative assessments are based on counting parasites by microscopy. | 4 years |
