Scuba divers could inadvertently be carrying coral disease from one reef to another, say scientists who have shown that bugs stick to wetsuits like glue. But a quick rinse in disinfectant can stop the spread.
Around 60% of the world's corals are thought to be under threat from warming seas, overfishing, pollution and coral diseases. Researchers have wondered whether ocean-hopping divers are playing a part by shipping disease-causing bacteria from an infected spot to a pristine one.
Diver and microbiologist Kay Marano-Briggs of George Mason University in Fairfax, Virginia, decided to investigate.
