The National Oceanic and Atmospheric Administration (NOAA) says that a virus is what is probably causing the hundreds of bottlenose dolphin deaths along the U.S. East Coast.
According to NOAA, More than 40 dolphins have been stranded between New York and North Carolina since July 1, more than nine times the average for that area and time of year. Because of this, the NOAA has declared the region and time period, from early July to present, as an Unusual Mortality Event (UME).
NOAA posted on its website, "The tentative cause of the UME is being attributed to cetacean morbillivirus, based upon preliminary diagnostic testing and discussion with disease experts." The investigation is still under way as the administration considers additional contributory factors.
