Loa loa filariasis

Loa loa filariasis is a skin and eye disease caused by the nematode worm Loa loa. It is a type of tropical infectious disease common in the rainforest areas of West and Central Africa. The disease is transmitted to humans through the bites of the deer fly or mango fly (Chrysops).

The transmission of Loa loa filariasis occurs when a human is bitten by an infected deer fly or mango fly. The flies become infected when they feed on the blood of a human who already has the disease. The larvae of the worm are then transmitted to the human host during subsequent bites.

Symptoms

The symptoms of Loa loa filariasis can vary greatly from person to person. Some people may have no symptoms at all, while others may experience severe reactions. Common symptoms include itching, swelling, and pain in the affected area. In some cases, the worms can be seen moving under the skin or in the eye.

Diagnosis

Diagnosis of Loa loa filariasis is typically made through a blood test. The worms can often be seen under a microscope in a blood sample. In some cases, the worms can also be seen moving under the skin or in the eye.

Treatment

Treatment for Loa loa filariasis typically involves medication to kill the worms. In some cases, surgical removal of the worms may be necessary.

Prevention

Prevention of Loa loa filariasis primarily involves avoiding bites from deer flies and mango flies. This can be achieved through the use of insect repellent and protective clothing.
