This map provides an indication of the broad patterns of coral disease around the world. However, many coral reef locations are unexplored and not all observations of coral disease are reported. “Other" includes skeletal eroding band, brown band, atramentous necrosis, trematodiasis, ulcerative white spots, and other syndromes that are poorly described.

Sources for the data are the ReefBase Coral Disease data set and the UNEP-WCMC Global Coral Disease Database.
