Corals get cold sores too. Only, for corals, a herpes virus infection isnâ€™t just annoying. It can be lethal, and it and other diseases are possibly a big factor in the deaths of coral reefs that humans are causing throughout the worldâ€™s oceans, new research shows.
Scientists have known for years that humans are killing corals indirectly and directly through global warming, overfishing and pollution. Many reefs off populous coasts have been decimated, while those near uninhabited areas are often thriving.
