“…blackflies, and infective larvae are incubated during the bite. The larvae mature to female and male worms within one year and are located in subcutaneous nodules (onchocercomata) [4]. The long-living females produce millions of microfilariae (first-stage larvae) during their lifetime, potentially causing dermatitis, lymphadenitis, and ocular lesions, which can progress to visual impairment and blindness [5].…”

“…Slightly infected individuals may remain asymptomatic with eosinophilia or elevated immunoglobulin E. Symptoms in travelers are primarily dermatologic in nature and may occur years after departure from endemic areas. The most prevalent cutaneous manifestation is a highly pruritic papular lesion, whereas more chronic changes can include atrophy, hyperkeratosis, and abnormal pigmentation [4]. Nodules are more common in endemic populations.…”

Onchocerciasis causes debilitating pruritus and rashes as well as visual impairment and blindness. Prior to control measures, eye disease was particularly prominent in savanna areas of sub-Saharan Africa whilst skin disease was more common across rainforest regions of tropical Africa. Mass drug distribution with ivermectin is changing the global scene of onchocerciasis. There has been successful progressive elimination in Central and Southern American countries and the World Health Organization has set a target for elimination in Africa of 2025. This literature review was conducted to examine progress regarding onchocercal skin disease. PubMed searches were performed using keywords ‘onchocerciasis’, ‘onchodermatitis’ and ‘onchocercal skin disease’ over the past eight years. Articles in English, or with an English abstract, were assessed for relevance, including any pertinent references within the articles. Recent progress in awareness of, understanding and treatment of onchocercal skin disease is reviewed with particular emphasis on publications within the past five years. The global burden of onchodermatitis is progressively reducing and is no longer seen in children in many formerly endemic foci.

Parasitic disease, commonly referred to as parasitosis, is an infectious process caused by a parasitic organism that thrives at the expense of its host. Human parasites can be classified into three main categories: protozoa, helminths, and ectoparasites (Chapter 34). Protozoans are small single‐celled organisms, such as the amoeba. Helminths on the other hand are larger multicellular organisms with internal organs and include the roundworm. Parasitic infections are well known for causing a significant burden of disease amongst the inhabitants of the tropic and subtropic regions of the globe and can be transmitted in several ways. The commonest methods of spread include contaminated water, soil and blood, or through transmission via infected insects that act as a vector or carrier of the disease. In this chapter we explore the common causes of cutaneous parasitic disease worldwide including their clinical signs, pathophysiology and therapeutic options.
