Biohazard name: Mass. Die-off (dolphins)

Scientists are working to unravel why there has been a surge in the number of beached dolphins found along the eastern coast of the U.S.. A total of 44 bottlenose dolphins were found in July, washed up along the southern part of Chesapeake Bay in Virginia - around eight times as many as normal, according to the Virginia Aquarium Stranding Response Team. Researchers are struggling to work out the cause of the deaths, but suspect a virus is to blame, as a similarly morbid bout of dolphin deaths occurred in 1987 and were the result of a measles-like disease. The National Oceanic and Atmospheric Administration has asked stranding centres situated along the coastline to record the number of dead dolphins found in a bid to find a pattern in the spikes. Susan Barco, research coordinator for the Virginia Aquarium & Marine Science Centre, told The Virginian-Pilot : 'We've had a steady number coming in at the beginning of the summer, and starting last week, the numbers spiked...We're just trying to keep our head above water.' The states of Delaware and Maryland has also seen a rise in dolphin deaths and according to a report in The Press of Atlantic City, around 10 dead dolphins were found in a month - double that than usually recorded. Scientists in New Jersey have reportedly said necropsy results have indicated pneumonia might be to blame, but a spokesman for NOAA's National Marine Fisheries Service admitted no-one knows what is causing the mysterious dolphin deaths but data is being collected.
