Summary extracts from Outlook Report 2009

• The incidence of coral disease may be increasing in some areas.
  
• A few instances of fish disease have been reported and a small number of stranded marine mammals and turtles show signs of disease (Cryptosporidium, Toxoplasmosis) linked to human activities. The very limited nature of these findings makes it difficult to interpret their significance.
• Fibropapillomatosis, believed to be caused by a virus, is most commonly found on green turtles. Higher incidence of the disease is noted in areas adjacent to large human populations and areas with low water turnover.
