Evaluation of community directed vector control on transmission of Onchocerca volvulus in a Loa loa co-endemic region
This study will pilot the Slash and Clear methodology in an oncho-Loa loa co-endemic setting. Previous pilots in Uganda and Nigeria have demonstrated that this simple strategy of removing breeding sites can result in significant black fly reductions that last for several months. This study will provide important data on the impact of Slash and Clear on black fly biting, and consequently its impact on oncho elimination. Two intervention and one control community will be compared for two years, with repeated measurements being taken of biting rates.
Reaching semi-nomadic groups using a test and treat (with doxycycline) strategy in a challenging onchocerciasis focus in West Region of Cameroon
- Is mobile outreach with a doxycycline test and treat strategy (TTd) an effective strategy in reducing onchocerciasis prevalence and intensity of infection amongst hard-to-reach nomadic groups in Massangam health area (HA)?
- What is the variation in prevalence of onchocerciasis and intensity of infection (community microfilaria load (CML)) in the different age and sex groups of hard-to-reach nomad community in the Massangam HA?
- What was the coverage of ivermectin mass drug administration in the nomad population with respect to the last round of ivermectin MDA?
- What is the cost of the mobile outreach strategy in this context, per person screened and treated?
Evaluate the current status of transmission of onchocerciasis in a hyperendemic area treated for many years and in a hypoendemic area treated for lymphatic filariasis for 5 years using the Ov16 ELISA and supplemented by entomology results from a previous study
Field friendly biometry to ease cohort studies in resource-limited settings: application to the Test and Treat for onchocerciasis project in Central Cameroon
Can a biometric recognition system, in the context of “Test and Treat”, facilitate individual follow-up by linking participant data at different time-points?
To pilot a strategy for mapping and treating Onchocerciasis and Lymphatic Filariasis in Loa loa co-endemic areas.
