ABSTRACT: Introduction: Lymphatic filariasis (LF) and malaria are two
vector-borne diseases which parasites can simultaneously infect
human or mosquito. In Burkina Faso, studies mainly focused on the control of
these diseases independently. Hence, there is a lack of information on their
co-transmission of to both human and vector. The present study aimed at
providing baseline data from endemic areas in
Burkina Faso towards a successful integrated management of both diseases. Methods: The study was carried out in
six sites distributed in the East,
Center-East and South-West regions of Burkina Faso. Data were collected
in August 2014 and September 2015. The infection rates in human and vector
populations, vector diversity, trophic and resting behavior were investigated. To
determine the disease prevalence nocturnal finger- prick blood sample
and microscopic observations were performed. Vectors collected by human landing catches and pyrethrum
spray collections. Biochemical and molecular analyses were performed to
identify Anopheles gambiae sensu
lato sibling species, and to determine vector infection
rate and their blood meal origins. Results: Results indicate
residual transmission of LF and malaria in human and vector populations. A low
co-infection rate (Wuchereria
bancrofti and Plasmodium
falciparum was noted in both human and mosquito. Anopheles gambiae s.l. , An. funestus s.l. and An. nili were by order the main potential vectors encountered. It was in majority parous
females and exhibited endophagic and exophagic behavior. Parasite’s co-infection was found with An. coluzzii and An. nili only. Conclusion: The present study has provided basic information on the (co-)transmission of
both diseases in the study areas. These results will be useful for further
investigations towards the development and implementation of a better
integrated strategy to control these diseases.
