The twenty-first century will continue to produce major
advances in medicines and medicine delivery. Nature is, however,
a resilient foe. Diseases and organisms develop resistance
to existing drugs, and new drugs must constantly be developed.
(This is particularly true for anti-infective and anticancer
agents.) Additionally, new and more lethal forms of existing
infectious diseases can develop rapidly.
With the ease of global travel, these can spread from Timbuktu to Toledo in less than 24 hours and become pandemics. Hence the current concerns with avian flu. Also, diseases that have previously been dormant or geographically circumscribed may suddenly break out worldwide. (Imagine, for example, a worldwide pandemic of Ebola disease, with public health agencies totally overwhelmed.) Finally, there are serious concerns regarding the possibility of man-made epidemics occurring through the deliberate or accidental spread of disease agents—including manufactured agents, such as smallpox with enhanced lethality. It is therefore imperative that the search for new medicines continue.
