Onchocerca volvulus is a parasitic worm responsible for the disease known as river blindness, primarily transmitted to humans through the bites of infected blackflies. This condition can lead to severe visual impairment or blindness, and it is a significant public health concern in certain tropical regions, particularly in sub-Saharan Africa.

Onchocerca Volvulus

Parasitic worm

River blindness, or onchocerciasis, is a neglected tropical disease caused by the parasitic worm Onchocerca volvulus, transmitted through the bites of infected blackflies. It leads to severe itching, skin discoloration, and can cause irreversible blindness, primarily affecting communities near fast-flowing rivers in sub-Saharan Africa and parts of Latin America and Yemen.

Visual impairment refers to a range of conditions that affect an individual's ability to see, which can vary from mild vision loss to complete blindness. It can be caused by genetic factors, injuries, or diseases, and often requires specialized tools and strategies for effective communication and navigation in daily life.

Visual Impairment

Blindness is the condition of lacking visual perception due to physiological or neurological factors. It can range from partial vision loss to complete absence of sight and significantly impacts an individual's interaction with their environment, necessitating adaptive strategies and technologies for navigation and communication.
