According to the World Health Organization (2018), so-called Neglected Tropical Diseases (NTDs) affect more than one billion people and cost developing economies billions of dollars every year. Populations living in poverty, without adequate sanitation and in close contact with infectious vectors such as livestock are most affected by these communicable illnesses, which prevail in tropical conditions. To complicate matters, diseases like measles and tuberculosis, which were nearly eradicated a century ago, are again on the rise. And more common, eminently treatable infectious diseases – norovirus and flu, for example – are responsible for thousands of preventable deaths each year.
