What is treatment for river blindness?
What is the treatment for onchocerciasis? Treatment is done by giving the patient ivermectin, an antiparasitic drug once or twice per year for about 10-15 years (the life span of adult worms). This antiparasite drug is effective in killing the microfilariae but does not kill the adult worms.
Does river blindness cause death?
Human onchocerciasis (River Blindness) is a parasitic disease leading to visual impairment including blindness. Blindness may lead to premature death, but infection with the parasite itself (Onchocerca volvulus) may also cause excess mortality in sighted individuals.
Is river blindness permanent?
People affected by onchocerciasis (river blindness) develop eye lesions which can lead to visual impairment and permanent blindness.
What are the ways to prevent and control onchocerciasis?
How can I prevent onchocerciasis? Blackflies bite during the day. The best prevention is avoiding being bitten by infected blackflies by using insecticides that contain N,N-Diethyl-meta-toluamide (DEET) on exposed skin, wearing long sleeve shirts and pants, and wearing permethrin treated clothing.
Can ivermectin cure river blindness?
More than 99% of infected people live in 31 African countries. Ivermectin, the only drug currently in use, distributed annually to entire communities living in endemic areas, has significantly reduced river blindness, but the global campaign to eliminate the disease requires also more effective drugs.
Is there a vaccine for river blindness?
River blindness is typically treated with the anti-parasite medication ivermectin, and the World Health Organization (WHO) notes that in the absence of a vaccine to prevent these infections, the disease has been largely mitigated or eliminated through insecticide spraying and other methods.
What causes trachoma?
Caused by the bacterium Chlamydia trachomatis, trachoma is easily spread through direct personal contact, shared towels and cloths, and flies that have come in contact with the eyes or nose of an infected person.
How do filarial worms cause blindness?
People are infected with river blindness (also known as onchocerciasis) by repeated exposure to blackflies that breed in fast-flowing rivers. The flies transmit worms that can cause severe itching and disfiguring skin lesions, and repeated infection can lead to blindness.
What is meant by river blindness?
River blindness: A disease caused by a parasitic worm (Onchocerca volvulus) that is transmitted by biting blackflies that breed in fast-flowing rivers.
How does river blindness affect the eye?
River blindness is transmitted to humans through the blackfly that lives along fertile riverbanks. Once a person is infected, the parasite migrates to all internal tissue of the eye except the lens, causing eye inflammation, bleeding, and other complications that lead to blindness.

What is the best treatment for river blindness?
1 Ivermectin. The most common way to treat onchocerciasis is by using ivermectin, a common drug used to treat other parasitic infections like scabies and elephantiasis. 2 Doxycycline. A relatively new treatment possibility for river blindness is doxycycline. 3 Preventive Methods. 4 A Word From Verywell.
How is river blindness spread?
It is spread by blackflies that carry the parasite. It can cause visual impairment, blindness, itching, and other skin diseases. ( Learn More) River blindness is a tropical disease, most common in specific parts of sub-Saharan Africa, but it’s also found in some parts of the Americas and Yemen.
Is river blindness still a neglected tropical disease?
While river blindness remains a significant neglected tropical disease, huge strides have been made to reduce the number of new diagnosed infections worldwide, especially in South America. Not everyone with onchocerciasis will have symptoms, especially not right away.
Can doxycycline be used to treat river blindness?
As a result, doxycycline isn’t yet considered to be a standard treatment for the condition—but the research on it is promising. The most serious symptoms of river blindness are the result of repeated exposure to the parasites. This is why preventing future infections is an important part of treatment.
