In the past two months, more than 300 bottlenose dolphins have washed up dead or dying on beaches stretching from New York to North Carolina, about 10 times the average for this period. An outbreak of cetacean morbillivirus, which suppresses the immune system and leaves those affected vulnerable to other diseases, is thought to be responsible for the “unusual mortality event,” as it has been designated by the National Oceanic and Atmospheric AdministrationMore… Discuss
