There is no question that mass drug administration (MDA) has had an enormous impact on disease burden but it needs to be recognized that these diseases are public health problems and our response to them needs to be through public health interventions that are beyond just preventive chemotherapy (PC). These diseases must be dealt with within a broader socio-economic development context. One of the key elements that will sustain the gains made by MDA for trachoma, soil transmitted helminths and schistosomiasis is the increased access to safe water, improved sanitation and the promotion of hygiene; commonly referred to as WASH. Integrating WASH with PC and promoting the behaviors that accompany WASH allows for a comprehensive control strategy such as trachoma has promoted for a number of years through the SAFE strategy.
