Lymphatic filariasis is a neglected tropical disease, transmitted by mosquitoes carrying filarial parasites. The disease damages the body’s lymphatic system and can lead to the enlargement of body parts in the legs, arms and breasts; this is known as lymphedema and swelling in the scrotal sack is known as hydrocele. Both lymphedema and hydrocele can cause severe pain, disability and social stigma.
