Brazil was certified by the World Health Organization for having eliminated lymphatic filariasis: what now?

Lymphatic filariasis (LF) is a debilitating and stigmatizing disease. In Brazil, the disease has been the target of control and elimination strategies for more than 25 years. Recently, the country received the certificate of elimination of LF as a public health problem. In this post-elimination moment, the question arises: what now? Given the possibility of emergence and reemergence of the disease, it is important that epidemiological surveillance measures are reviewed and applied effectively.
