Coral diseases that are distributed throughout an area can have a big impact on other parts of reef communities. Not only do coral diseases impact the overall accretion and surface area of the coral, it also affects coral reproduction, the diversity and prosperity of reef species, topography of structures, and community dynamics.

It is a disease that can destroy miles of coral reef fast. A disease such as white plague can spread over a coral colony by a half an inch a day. By the time the disease has fully taken over the colony, it leaves behind a dead skeleton. Dead standing coral structures are what most people see after disease has taken over a reef.
Huge stretches of coral reef around the world are turning a ghostly white this year amid record warm ocean temperatures. ... "We get a fever to resist a disease, and if the disease is not too much ...
Coral reefs may therefore be "squeezed into a narrower latitudinal distribution by ocean warming in the tropics, and ocean acidification in cooler oceans." [2] This phenomenon has been referred to as the global poleward migration of coral species - who are seeking cooler climates - or to the growth of coral in temperate regions.
Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists declared Monday, a result of warming ocean waters amid human-caused climate change. Coral ...
In 2018, the United Nations Intergovernmental Panel on Climate Change estimated that 70% to 90% of the world’s coral reefs would disappear if global average temperatures crossed a threshold of 1 ...
Yellow-band disease is a bacterial infection that spreads over coral, causing the discolored bands of pale-yellow or white lesions along the surface of an infected coral colony. The lesions are the locations where the bacteria have killed the coral's symbiotic photosynthetic algae, called zooxanthellae which are a major energy source for the ...
Over 50% of the world's coral reefs may be destroyed by 2030; as a result, most nations protect them through environmental laws. [103] In the Caribbean and tropical Pacific, direct contact between ~40–70% of common seaweeds and coral causes bleaching and death to the coral via transfer of lipid-soluble metabolites. [104]
