  • It was first spotted decades ago and has caused widespread damage to the reefs in the Caribbean.
  • Corals cannot remain alive when they are exposed to this yellow-band disease. They will die gradually.
  • The reef is “like a forest” sustaining massive amounts of life, and its death could eventually impact humans too.
  • They are rushing to find a treatment.
  • 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 coral.
