The American Society of Tropical Medicine and Hygiene (ASTMH) is an Arlington, Virginia-based non-profit organization of scientists, clinicians, students and program professionals whose longstanding mission is to promote global health through the prevention and control of infectious and other diseases that disproportionately afflict the global poor.

Soon after its founding, ASTM began to expand beyond Philadelphia, holding annual meetings in Baltimore, New York City and Washington, D.C., in its first five years of existence.

Among other early members and leaders, ASTM's fourth president, William Crawford Gorgas, played a role in battling yellow fever in Panama.

Passing the examination leads to a Certificate of Knowledge in Clinical Tropical Medicine and Travelers' Health (CTropMed).

In the last decade, ASTMH has become increasingly involved in policy and advocacy activities, particularly advocating for U.S. federal funds to fight tropical diseases worldwide and improve global health.
