Viehoff et al., (2014) reports that there are approximately 140 to 250 million people worldwide affected by lymphedema. The same author states that there is an estimated 120 million impacted by lymphedema in 72 countries, concurrently or previously infected with lymphatic filariasis. 15 million of those were positively confirmed to have lymphedema as reported in the World Health organization.
