Each year, the American Society of Tropical Medicine and Hygiene (ASTMH) honors select individuals with medals recognizing exceptional contributions in tropical medicine and global health. These are the highest honors the Society bestows. They are awarded at the Annual Meeting. ASTMH awarded three Society-level medals and introduced a fourth at the 66th Annual Meeting in Baltimore on November 5, 2017, as follows. The Clara Southmayd Ludlow Medal is described in the preceding article.
