SCTLD can spread rapidly, at a pace of 20- regimes; however, this is still being tested and Department of Environmental Protection 40 cm2 a day for highly susceptible coral species regulatory frameworks concerning the use of such (DEP)’s management of this disease and discuss and 5-10 cm2 a day for intermediately susceptible treatments varies between countries best practices for identifying and treating species (Martinelli, 2019). Without intervention, (Reef Resilience, 2019). infected corals. Florida has seen nearly a 100% mortality rate of infected corals with this disease (Martinelli, 2019). Protecting the Future The Disease With harsher environmental conditions stressing A new coral disease was first spotted off the Transmission corals, these species will continue to become coast of Florida in 2014. Since then, it has spread It is now believed the SCTLD is transmitted more susceptible to disease in the future. SCTLD throughout much of the north Caribbean, through direct contact and water circulation is of particular concern as it appears to be long including Mexico, Jamaica, Sint Maarten, the (Reef Resilience, 2019). To minimize its spread, lasting (present since 2014), easily spread over Dominican Republic, and the U.S. Virgin Islands officials are now recommending extreme caution a wide area, it affects a high number of slow (AGGRA, 2019). This disease is known as SCTLD for divers around infected corals, and urge divers growing, reef building species and has been seen and to date it has only been seen in stony corals to fully decontaminate their gear between dive to result in total colony mortality once infected and causes significant tissue loss within affected sites to avoid spreading the disease (Florida DEP, (Martinelli, 2019).
