Lymphatic diseases caused by filariasis are a significant public health problem in affected countries. People suffering from lymphoedema caused by this worm, even if the morbidity has been limited and—to a limited extent—even eliminated, need the crucial support of the respective national health authorities. Eliminating the cause of this secondary lymphoedema has not yet been achieved across the board, although tremendous and remarkable progress has already been made. Patients with filariasis do not differ in principle from all other lymphoedema patients in terms of treating lymphoedema. Nevertheless, there is a specific problem with the availability of aids such as manual lymphatic drainage, compression and possible surgical interventions. The first steps in the right direction have been taken for many years (see ► Chap. 5 ). Nevertheless, it remains essential to establish and implement programs for treating lymphedema in the coming decades so that lymphoid infectious diseases caused by filariasis and podoconiosis and new cases in this area can be reduced to less than 1% per year.
