SealWatch.org is preparing an Alert page about the current outbreak of Phocine Distemper Virus in northern Europe, apparently originating again from the islands of Denmark and potentially spreading to other countries. Harbor/common seals are at the greatest risk; the last epidemic was catastrophic. Although we have access to scientific studies on the etiology and epidemiology of the disease, and are compiling a list of those marine mammal rescue stations most likely to be involved at the forefront of response in the near term, we do not have a reference to a general treatment of the disease for an concerned, informed, but non-technical audience. Any suggestions for an appropriate online resource to which we can direct visitors seeking further information would be appreciated.
