CONFIRMED DISTEMPER VIRUS IN FERRETS
For the last five to six weeks the National Ferret Welfare Society (NFWS) has been investigating a substantial number of ferret deaths which have been reported in various areas up and down the country, but mainly concentrated in the Midlands and Cheshire counties.
As part of its investigations, the Society has paid for several detailed post mortems and some pcr (polymerase chain reaction) swab tests. However whilst the latter came back testing positive for distemper, the post mortem results were needed to confirm whether or not distemper was the cause.
Today (14th November), we have received the results of the post mortems which were done in conjunction with Mr Simon Thomas BSc BVetMed CVR CSAO MRCVS and the Infectious Diseases Diagnostic Unit at the University of Glasglow School of Veterinary Medicine;
The results – Distemper. Confirmed. As yet we do not know which strain. Mr Thomas has spoken to the vaccine manufacturer and has advised that if you do vaccinate your ferret(s) then it is best to use Nobivac DHP, 1 dose (vial) per ferret. (REMEMBER this vaccine is not licensed for ferrets). However this will not protect your ferret if they have already come into contact with another infected animal. Whether or not you vaccinate your ferret(s) is a decision only you as an owner can make.
The signs to look out for, in order of importance, are:-
i) Rash – pink with black coloured tip. Mainly appears in the abdominal area, worsening around the groin. Can also appear around the eyes and under the chin and, in some cases can been seen all over.
ii) Crusting around the eyes; sensitive to light. May or may not have discharge AND
iii) Crusting around the nose. May or may not have discharge.
iv) Pads may well swell to double in size as symptoms progress and become 'crusty'.
Symptoms are typically taking between 7 to 21 days to appear and not all ferrets within an infected group develop symptoms at the same time. There can be several weeks between the first ferret(s) displaying signs of distemper and the last ferret(s), more confusingly, not all ferrets within an infected group show symptoms or appear to develop this illness.
Please note that apart from swollen, crusty pads the other symptoms can be a sign of something else, remembering of course that at this time of year human flu can be passed on to ferrets, BUT if your ferret is displaying these signs then please advise your vet of this before going to the surgery so that they can put their own additional protocols in place. Remember that not all ferrets that die, will die of this illness. As always, if you have a ferret that is unwell then please seek veterinary advice.
Precautions to take include not mixing your ferrets with other groups of ferrets, refrain from walking ferrets in public areas that dogs and other ferrets have access to, avoid contact with strange and/or unwell ferrets belonging to another person. This is not exhaustive but hopefully will help you to decide whether or not to do something/go somewhere with your ferret(s).
YOUR HELP IS NEEDED:- We now need to map which areas have had ferrets die of this illness, be it one ferret or more. In order to make this as accurate as possible, we will need to differentiate between suspected and confirmed cases. However, all information will be recorded so please either email, telephone or write to me (Bennie Lye, National Ferret Welfare Society, 1 The Terrace, Loddiswell, Kingsbridge, Devon. TQ7 4RH. Tel: 01548 550156. Email:
herbielye@aol.com). Any personal details will be kept confidential but in order to assist, information on the veterinary surgery involved will help as then we can also record (a) what tests, if any, were carried out (b) if vaccinated/when/ vaccine used/dosage and (c) what symptoms were presented.
As soon as we have more information we will let you know but in the meantime, give your loveable, mischievous hooligan(s) an extra big hug.
