Can Black Flies carry diseases?
Yes, they have been known to transmit diseases to humans and animals. In Africa, Central America and South America, they can transmit two diseases to humans: onchocerciasis, known as “river blindness,” and mansonellosis. In many countries of the world, Black Flies transmit diseases to animals including bovine onchocerciasis in cattle and horses, and leucocytozoonosis in wild birds.
