Art meets Science - Detail #6 - River Blindness and Elephantiasis

Onchocerciasis, also known as river blindness and Robles disease, is a disease caused by infection with the parasitic worm Onchocerca volvulus. Symptoms include severe itching, bumps under the skin, and blindness. It is the second most common cause of blindness due to infection, after trachoma.
Lymphatic filariasis also known as elephantiasis is caused by parasitic worms of the Filarioidea type. Many cases of the disease have no symptoms. Some however develop large amounts of swelling of the arms, legs, or genitals. The skin may also become thicker and pain may occur. The changes to the body can result in social and economic problems for the affected person. (Wikipedia)
Both diseases are transmitted by mosquitoes.
