Hi, well, bearing in mind we were a group of about 10 people all clustered around looking at the very heavily pregnant Kaylee and the questions were being fired thick and fast the Keeper explained it was very like the cold sore virus in humans, this virus lies dormant in the body until symptoms show and you can’t test for it while it is dormant.
He assured us all the elephants are checked for early symptoms three times a day by keepers and the national stock of the drug used to treat them is held by Whipsnade.
ZSL is putting a lot of money, time and resources into the global efforts to find a cure or vaccine for this virus, but until then the best they can do is to be extremely vigilant in recognizing early signs so that treatment can be started without delay. There are examples of calves who have survived after the treatment (ie. in St Louis Zoo) but obviously, as was the case with Donaldson and Leelee, even early, comprehensive treatment is not always enough and not enough is known about how the virus replicates to stop it in its tracks.
Kaylee was pregnant for over 18 months before Donaldson and Leelee died, so rather than intervene they are being very pro active and vigilant with the care of the animals at ZSL Whipsnade as well as pursuing their research for treatment or cure. I hope and pray that this little one will survive under their care and am looking forward to my visit next month.
