July 2017 – The first signs of what was later recognized as SCTLD along the Jamaican north coast occurred in several Meandrina jacksoni colonies in July 2017, followed by some Dendrogyra cylindrus and Siderastrea siderea in the fall. The prevalence of sick and dying corals on north Jamaican reefs increased dramatically in spring 2018, especially among Pseudodiploria strigosa, Diploria labyrinthiformis, Colpophyllia natans and, Montastraea cavernosa. By November, SCTLD was observed in the Orbicella species complex.
