A new study by the Zoological Survey of India (ZSI) has used Deoxyribonucleic Acid (DNA) barcoding to correctly identify blackfly species that spread river blindness. River blindness, also called Onchocerciasis, is caused by the parasitic worm Onchocerca volvulus and spreads through the bite of infected blackflies of the genus Simulium. These blackflies breed near fast-flowing rivers and streams and mainly affect people in rural and remote areas. The disease causes severe skin itching, skin damage, and in serious cases, permanent blindness. The World Health Organization (WHO) classifies river blindness as a major Neglected Tropical Disease (NTD), especially in sub-Saharan Africa, Yemen, and Latin America.
