Article Synopsis
- The study highlights that despite continuous mass drug administration (MDA) with ivermectin in Ghana, onchocerciasis transmission remains an issue in certain areas, evidenced by ongoing infections in endemic communities.
- Researchers collected nearly 10,000 black flies to analyze their species composition and determine transmission patterns, finding that almost all flies (99.8%) were savanna species.
- High biting rates and potential transmission indices were recorded, indicating significant continued disease risk, while cytogenetic studies identified three distinct black fly cytospecies linked to the transmission of the parasite.
Background: Simulium damnosum sensu lato (s.l.) blackflies transmit Onchocerca volvulus, a filarial nematode that causes human onchocerciasis.

To test its field applicability, we used this platform to detect the presence of filarial and malaria parasites in two villages of Ghana and compared results to those for detection in mosquito carcasses and human blood. We compared the molecular detection of three parasites (Wuchereria bancrofti, Plasmodium falciparum and Mansonella perstans) in mosquito E/F, mosquito carcasses and human blood collected from the same households in two villages in the Savannah Region of the country.
