A marked peripheral eosinophilia is often present. If the parasitic infection is low, eosinophilia may be the only diagnostic sign evident. Occasionally, splinter hemorrhages may be present below the nails. [clinicalgate.com]

Calabar swellings are subcutaneous edematous areas of 3-10 cm that are nonerythematous and do not pit; local pain, pruritus, and mild fever may be present. [antiinfectivedrugs.com]

The most common presenting feature is abdominal pain, observed in 98% of patients. Less common features include ascending cholangitis, acute pancreatitis, and, rarely, obstructive jaundice. [emedicine.medscape.com]

Treatment The treatment of choice is ivermectin, 150 5g/kg orally as a single dose, which kills microfilariae but is less effective against adult worms. Treatment is repeated at 3-mo intervals for 2-3 years. [antiinfectivedrugs.com]

Treatment is usually with thiabendazole or albendazole. Enterobiasis Enterobius vermicularis (the threadworm) is cosmopolitan. [oxfordmedicine.com]

Treatment If asymptomatic then no treatment is required. Otherwise, either diethylcarbamazine or ivermectin is effective. [patient.info]

Prognosis Prognosis depends on the stage at which the infection is treated. If treated early during the course of the disease, the corneal opacities may be minimal and may recede with appropriate treatment. [eyewiki.aao.org]

Surgery Surgical interventions can be directed at the underlying etiology of vision loss. Cataract extraction can be performed on visually significant cataracts induced by the disease process. [eyewiki.aao.org]

Epidemiology It is estimated that 2-13 million humans are infected with the Loa loa larvae. [patient.info]

As will be explained further, eradication of the disease is relatively simple and is in near sight--eradication can be accomplished simply by preventing people from drinking from water contaminated by the parasite. [web.stanford.edu]

Prevention (Sanitation and Exclusion) Use certified clean, nematode-free seed. Stem nematode is not seedborne, but can live on alfalfa chaff. [ipm.ucanr.edu]

However, the focus should also be on prevention to avoid a recurrence of the infection. The worms do not have to be removed surgically unless large number of worms are causing an obstruction, or other complications. [healthhype.com]
