Abstract:

Onchocerciasis caused by infection with Onchocerca volvulus is a disease of public health importance and is highly associated with disability. As Nigeria is aiming at eliminating onchocerciasis by 2030, there is a need to develop newer tools to map disease prevalence and identify environmental factors driving disease prevalence, even in places that have not been previously targeted for preventive chemotherapy. This study produced predictive risk-maps of onchocerciasis in Ogun State. Georeferenced onchocerciasis infection data obtained from a cross-sectional survey at 32 locations between March

Background Onchocerciasis affects the quality of life to a greater extent among affected individuals.

Despite the successful reduction of the prevalence of onchocerciasis by WHO, the socioeconomic burden resulting from the disabilities caused by onchocerciasis are still immense.

Based on the observation that the parasite Onchocerca volvulus selectively absorbs vitamin A from the host, and the known toxicity of vitamin A in higher concentration, it was hypothesized that dying microfilariae (mf) release their stores of vitamin A (retinoids) into the host circulation in toxic concentrations, inducing the signs and symptoms of onchocerciasis.

A high onchocerciasis microfarial load increases the risk to develop epilepsy in children between the ages of 3 and 18 years. In resource-limited settings in Africa where onchocerciasis has been poorly controlled, high numbers of onchocerciasis-associated epilepsy (OAE) are reported.

Abstract:

One of the most debilitating consequences of aging is the progressive decline in immune function, known as immunosenescence. This phenomenon is characterized by a shift in T-cell phenotypes, with a manifest decrease of naive T-cells—dealing with newly encountered antigens—and a concomitant accumulation of senescent and regulatory T-cells, leading to a greater risk of morbidity and mortality in older subjects. Additionally, with aging, several studies have unequivocally revealed an increase in the prevalence of onchocerciasis infection. Most lymphatic complications, skin and eye lesions due to

Abstract:

Background: Onchocerciasis or river blindness is a parasitic disease caused by the filarial Onchocerca volvulus. People living in savannah and forest areas of Central African Republic (CAR) are exposed to onchocerciasis due to the increased presence of the transmissible agent. In order to achieve the objective of mass distribution of Ivermectin, the community must join in the fight against the disease. Methods: A multicentric KAP analytical study took place in two endemic sub-prefectures, one in the savannah zone and the other in the forest in the CAR. All persons aged 15 years and over who ag

Abstract:

BACKGROUND: Onchocerciasis or river blindness constitutes a major burden to households especially in resource-poor settings, causing debilitation and reduction in household productivity. It is an endemic disease in Nigeria. The study aimed to determine the effect of health education on knowledge, attitudes and practices towards onchocerciasis.METHODS: This study was an intervention study carried out among 282 respondents. A multistage sampling technique was used to select the study sample. RESULTS: Both study and control groups had poor knowledge, 40.4% and 41.2% respectively pre-intervention.

Abstract:

Wadelai, an isolated focus for onchocerciasis in northwest Uganda, was selected for piloting an onchocerciasis elimination strategy that was ultimately the precursor for countrywide onchocerciasis elimination policy. The Wadelai focus strategy was to increase ivermectin treatments from annual to semiannual frequency and expand geographic area in order to include communities with nodule rate of less than 20%. These communities had not been covered by the previous policy that sought to control onchocerciasis only as a public health problem. From 2006 to 2010, Wadelai program successfully attaine
