Advice for travellers
Screwworm is a disease caused by the larvae of the fly Cochliomyia hominivorax (Coquerel) , which lays its eggs in any open wound of a warm-blooded animal, including people. Hours after they have been deposited, the worms are born, which feed on the living tissue.
The larvae hatch and develop under the skin causing a condition known as cutaneous myiasis.
Symptoms include the presence of a painful lump on the skin that may secrete fluid. As the larva grows, it may be visible under the skin and can often be felt moving. Treatment usually involves surgical removal of the larva, followed by local care to prevent infection. Read more
