Loa loa filariasis

Loa loa filariasis (pronunciation: /ˈloʊ.ə ˈloʊ.ə fɪˌlɛərɪˈæsɪs/), also known as Loiasis or Calabar swelling, is a parasitic disease caused by the nematode (roundworm) Loa loa. The disease is transmitted to humans through the bite of a deer fly or mango fly, which are the vectors of the parasite.

Etymology

The term "Loa loa" originates from the Mangbetu language spoken in the Democratic Republic of Congo, where the disease is prevalent. The term "filariasis" is derived from the Latin word "filum", meaning "thread", which refers to the thread-like appearance of the adult worms.

Symptoms

The symptoms of Loa loa filariasis include itching, swelling, and pain in the affected areas. In some cases, the adult worms can be seen moving under the skin or in the eye, a condition known as subconjunctival migration.

Diagnosis

Diagnosis of Loa loa filariasis is typically made through microscopic examination of a blood sample, where the presence of microfilariae (the larval stage of the parasite) can be detected.

Treatment

Treatment for Loa loa filariasis typically involves the use of antiparasitic drugs, such as diethylcarbamazine (DEC) or ivermectin. In severe cases, surgical removal of the adult worms may be necessary.
