The lymphatic form of filariasis usually produces fever, swollen or painful
lymph nodes in the neck and groin, pain in the testicles, and swelling
in the limbs or genitals. Males and the male urinary and genital systems
are particularly likely to be affected. In elephantiasis, a severe form of
chronic lymphatic filariasis, the blocked flow of lymph causes one or
both legs to swell significantly. Over time, the skin on the leg can also
change, taking on a rough texture so that it resembles the skin of an
elephant. Although elephantiasis is unusual, up to half of all men with
lymphatic filariasis may show serious symptoms, such as swelling of the
scrotum. In some cases people may have no obvious symptoms, but they
still may have serious damage to the kidneys and lymphatic system.

Making the Diagnosis
Knowing that the person lives in or has spent time in a country where
filariasis poses a risk can help a doctor diagnose the disease. The doctor
may also take skin and blood samples from the patient to look for signs
of the parasite.
