BackgroundOnchocerciasis is caused by a nematode worm Onchocerca volvulus, which is transmitted in Sudan by black fly vectors of the Simulium damnosum sensu lato species complex. In Sudan, the disease is found in four foci where fast flowing rivers provide suitable breeding sites for the Simulium vector flies. The construction of dams and irrigation schemes for agricultural purposes has affected black fly breeding and distribution, such as in Merowe Dam in Abu-Hamed focus, where the perennially… Expand

The Galabat-Metema cross-border onchocerciasis focus: The first coordinated interruption of onchocerciasis transmission in Africa
TLDR
Coordinated stop MDA decisions were made by Sudan and Ethiopia based on data satisfying the World Health Organization’s criteria for interruption of onchocerciasis transmission in 2018, with the exception of the hotspot at Wudi Gemzu, where MDA with ivermectin was increased to every three months to hasten interruption of transmission.

Socioeconomic impacts of elimination of onchocerciasis in Abu-Hamed focus, northern Sudan: lessons after elimination
TLDR
The findings revealed that these communities are recovering from the social and economic burden of the diseases and were engaged in normal daily life activities and involved in happy events like marriage and giving birth during the last 12 months. Expand
The Emergence of Rift Valley Fever in Gedaref State Urges the Need for a Cross-Border One Health Strategy and Enforcement of the International Health Regulations
TLDR
The policymakers of the health and animal resources sectors are urged to implement a one health strategy with a well-established early warning surveillance and response system to prevent the establishment of the disease in the area. Expand

The impact of Merowe Dam on Simulium hamedense vector of onchocerciasis in Abu Hamed focus - Northern Sudan
TLDR
The Dam seems to have positive impact on onchocerciasis and its black fly vectors in Abu Hamed focus, and these outcomes of the Merowe Dam might have contributed to the recently declared interruption of onchopercciasis transmission in AbuHamed focus. Expand
Seasonal Variation in Biting Rates of Simulium damnosum sensu lato, Vector of Onchocerca volvulus, in Two Sudanese Foci
TLDR
Transmission of onchocerciasis in both foci showed marked differences in seasonality, which may be attributed to ecology, microclimate and proximity of breeding sites to collection sites, and variations in climate zones. Expand
BIOECOLOGY OF SIMULIUM DAMNOSUM THEOBALD COMPLEX ALONG OSUN RIVER, SOUTHWEST NIGERIA
TLDR
The results suggest that the climatic and environmental conditions influence the distribution of S. damnosum s.l in the study area, and the presence of the fly all year round calls for adequate control measures to curtail the transmission of onchocerciasis in particular during the wet season.

TLDR
The distribution of onchocerciasis and its vectors in Sudan has been reviewed with special emphasis on the hyperendemic foci where there is serious visual handicap caused by the disease, suggesting that a strategy of tackling the disease on a focus basis may prove optimal. Expand
Polymerase chain reaction pool screening used to compare prevalence of infective black flies in two onchocerciasis foci in northern Sudan.
TLDR
Assessment of more than 30,000 black flies for Onchocerca volvulus infectious stage L3 larvae by using an O-150 polymerase chain reaction protocol showed that black fly infectivity rates were 0.84 per 10,000 flies for Abu Hamed and 6.4 for Galabat, providing entomologic evidence for suppressed Onch Cocerciasis transmission and a moderate transmission rate of the parasite in theGalabat focus.

Ocular onchocerciasis: current management and future prospects
TLDR
It seems unlikely that a break in transmission will occur with community-directed treatment with ivermectin in Africa because of population migrations and the highly efficient vector, but in the Americas some countries such as Columbia and the Oaxaca focus in Mexico have reported eradication.
