><p>Onchocerciasis (river blindness) is a neglected tropical disease manifesting clinically as skin and eye problems. It is caused by the parasite Onchocerca volvulus, transmitted by the blackfly insect. It is the world\u2019s second-leading cause of preventable blindness, with 99% of the almost 21 million infected people living on the African continent.<\/p>\n<p>Epidemiological evidence suggests that infection with this parasite can also induce neurological conditions such as epilepsy and neurocognitive decline; furthermore, the painful bites of blackflies are a source of nuisance and psychological distress among affected communities. Blackflies breed best in fast-flowing fresh waters. It is a pest in several countries, including Cameroon, where the construction of dams has created conducive circumstances for the blackfly vector to thrive.<\/p>\n<p>Thus far, attempts to control these insects have involved the use of chemicals to kill the developing larvae in rivers, often resulting in adverse repercussions for the environment and the emergence of resistance against the larvicides used. This option is also expensive and requires advanced technical skills for implementation. As a result, the approach was abandoned, leaving several communities helpless in the face of blackfly nuisance and onchocerciasis-associated morbidity.<\/p>\n<p>During his PhD, Dr Joseph Nelson Siewe Fodjo tested a greener, more sustainable solution to this problem around the Maridi dam in South Sudan. He is extending the scope of his work with his Future Africa Research Leader Fellowship (FAR-LeaF) project, titled \u2018Eco-friendly approach to reduce onchocerciasis transmission around the Edea dam in Cameroon\u2019.<\/p>\n<p>His team\u2019s novel \u201cslash and clear\u201d technique will reduce the blackfly population around the dam. With the use of machetes, they will cut down trailing vegetation and other breeding substrates on the fast-flowing downstream section of the dam. In South Sudan, they found that a single \u201cslash and clear\u201d intervention was enough to drastically decrease the blackfly population in the surrounding villages for months. Mathematical models suggest the process can significantly accelerate onchocerciasis elimination prospects in endemic sites.<\/p>\n<p>The technique has the advantage of being less dangerous for the aquatic environment as larvicidal chemicals are not being poured into rivers. Trained local villagers can perform the technique making it a sustainable option and one that can be a source of income in the long term. This is important because several dams are being constructed across the Sanaga River of Cameroon for hydroelectricity generation, and many villages and communities nearby have experienced a surge in blackfly bites, rekindling onchocerciasis transmissions.<\/p>\n<\/div><\/section><\/div>\n<\/div><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-xqn0z-520516ab94f4f7aae0ce6ba43d608983\">\n.flex_cell.av-xqn0z-520516ab94f4f7aae0ce6ba43d608983{\nvertical-align:top;\nbackground-color:#f8f8f8;\n}\n<\/style>\n<div class='flex_cell av-xqn0z-520516ab94f4f7aae0ce6ba43d608983 av-gridrow-cell av_one_half no_margin  avia-builder-el-9  el_after_av_cell_one_half  avia-builder-el-last  content-align-top'  ><div class='flex_cell_inner'><p><div  class='flex_column av-rz6nv-79587972f833763af6466d1f80169869 av_one_full  avia-builder-el-10  el_before_av_three_fifth  avia-builder-el-first  first flex_column_div av-animated-generic left-to-right  '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lylpz19y-47d26f9dda3d4d3ba262b51b3534c461\">\n#top .av_textblock_section.av-lylpz19y-47d26f9dda3d4d3ba262b51b3534c461 .avia_textblock{\ntext-align:justify;\n}\n<\/style>\n<section  class='av_textblock_section av-lylpz19y-47d26f9dda3d4d3ba262b51b3534c461 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>The research will investigate whether or not the new technique will derange the ecological balance around the rivers during the months following its implementation. The project will be piloted around the Edea dam, where necessary blackfly nuisance and high burdens for both onchocerciasis and epilepsy have been documented. If proven to be more beneficial than harmful, the technique could be replicated at other dam sites, thus improving the health and well-being of communities.<\/p>\n<p>Dr Siewe Fodjo will measure blackfly biting rates before and after the intervention using specially designed blackfly traps, and will interview indigenous people about notable changes regarding blackfly nuisance and diseases in their community. The reduction of blackflies in the area is expected to last many months, and local volunteers will be taught to repeat the intervention without supervision.<\/p>\n<p><strong><small>Dr Joseph Nelson Siewe Fodjo is a medical doctor (MD in General Medicine from the University of Yaound\u00e9 I, Cameroon) and holds a PhD in clinical epidemiology\/epilepsy from the University of Antwerp, Belgium. Currently based in Cameroon, he serves as a research officer at the Brain Research Africa Initiative. As a research physician, he is interested in tropical diseases, particularly onchocerciasis (river blindness). He has cumulated years of field experience in several African countries where he conducted onchocerciasis and epilepsy surveys in remote villages. His research shows significant associations between exposure to onchocerciasis and neurological symptoms (seizures and cognitive decline), suggesting that this infection has long-term central nervous system consequences even after the causative agent has been eradicated.<\/small><\/strong><\/p>\n<\/div><\/section><\/div><div class='flex_column_table av-8j9v-136b5421205b12cd8ae6089b346d18ab sc-av_three_fifth av-break-at-tablet-flextable av-equal-height-column-flextable'>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-8j9v-136b5421205b12cd8ae6089b346d18ab\">\n.flex_column.av-8j9v-136b5421205b12cd8ae6089b346d18ab{\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-8j9v-136b5421205b12cd8ae6089b346d18ab av_three_fifth  avia-builder-el-12  el_after_av_one_full  el_before_av_two_fifth  first no_margin av-break-at-tablet flex_column_table_cell av-equal-height-column av-align-middle av-animated-generic left-to-right av-zero-column-padding  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lylpz9za-3ffb90f3d62af9c93d21fefb0cdb8928\">\n.avia-image-container.av-lylpz9za-3ffb90f3d62af9c93d21fefb0cdb8928 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lylpz9za-3ffb90f3d62af9c93d21fefb0cdb8928 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lylpz9za-3ffb90f3d62af9c93d21fefb0cdb8928 av-styling- avia-align-center  avia-builder-el-13  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-196 avia-img-lazy-loading-not-196 avia_image ' src=\"https:\/\/www.futureafrica.science\/farleaf\/wp-content\/uploads\/sites\/3\/2024\/07\/Joseph-01.jpg\" alt='' title=''  height=\"338\" width=\"600\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/www.futureafrica.science\/farleaf\/wp-content\/uploads\/sites\/3\/2024\/07\/Joseph-01.jpg 600w, https:\/\/www.futureafrica.science\/farleaf\/wp-content\/uploads\/sites\/3\/2024\/07\/Joseph-01-300x169.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/div><\/div><\/div><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-f8zaj-6daa0b1e0ce60f5435698b1e25e751fb\">\n.flex_column.av-f8zaj-6daa0b1e0ce60f5435698b1e25e751fb{\npadding:0px 15px 0px 15px;\nbackground-color:#1a78bd;\n}\n\n@media only screen and (min-width: 480px) and (max-width: 767px){ \n.flex_column.av-f8zaj-6daa0b1e0ce60f5435698b1e25e751fb{\npadding:15px 15px 15px 15px;\n}\n}\n\n@media only screen and (max-width: 479px){ \n.flex_column.av-f8zaj-6daa0b1e0ce60f5435698b1e25e751fb{\npadding:15px 15px 15px 15px;\n}\n}\n<\/style>\n<div  class='flex_column av-f8zaj-6daa0b1e0ce60f5435698b1e25e751fb av_two_fifth  avia-builder-el-14  el_after_av_three_fifth  avia-builder-el-last  no_margin av-break-at-tablet flex_column_table_cell av-equal-height-column av-align-middle av-animated-generic left-to-right  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lylpzimt-33cc96f2800e5e1f604036bf2a9686a1\">\n#top .av_textblock_section.av-lylpzimt-33cc96f2800e5e1f604036bf2a9686a1 .avia_textblock{\ncolor:#ffffff;\ntext-align:justify;\n}\n<\/style>\n<section  class='av_textblock_section av-lylpzimt-33cc96f2800e5e1f604036bf2a9686a1 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock av_inherit_color'  itemprop=\"text\" ><p style=\"text-align: center;\"><strong>Dr Joseph Nelson Siewe Fodjo<\/strong><\/p>\n<p style=\"text-align: center;\">FAR-LEAF Research Fellow<br \/>\nBrain Research Africa Initiative (BRAIN)<br \/>\n<strong>Cameroon<\/strong><\/p>\n<\/div><\/section><\/div><\/div><!--close column table wrapper.
