Mass Drug Administration
Mass drug administration (MDA) is a phrase that refers to the administration of various drugs to entire populations whether or not disease is prominently present. This is a technique that has been used to intervene in the spread of malaria for more than 70 years. With respect to MDA, medicines are administered in one of two ways: directly or indirectly. With direct MDA, a therapeutic dose of a drug—an antimalarial drug, for example—will generally be given to an entire population. With indirect MDA, medicines are typically incorporated into meals and beverages.
