Interim ICC Report – February 2019 #14 (22.02.19)

Interim Report Feb 19 #12 (22.02.19) – Report from Denmark on Equine Influenza (EI), Sweden on Equine Influenza (EI) & USA on Strangles


Equine Influenza (EI)

On 20 February 2019, it was confirmed that an elderly vaccinated pony tested positive for EI by PCR on a nasopharyngeal swab. The pony had been imported from the UK to Sweden and had clinical signs consistent with EI when arriving at the stable in Sweden. The horse then attended the veterinary hospital at Copenhagen University and was immediately isolated on the basis of its clinical signs on arrival and the history of importation from the UK. The veterinary hospital have contacted stables and veterinary practices in Sweden where other horses transported with this case are situated. The situation is being monitored closely.



Equine Influenza (EI)

On 21 February 2019, National Veterinary Institute reported that there had been several confirmed cases of EI in Sweden in February, all directly connected to each of several registered shipments of horses arriving from Ireland and possibly the UK. During February, Sweden received several shipments of horses and ponies infected with equine influenza and their port of origin have mainly been Ireland but the UK is also under investigation. These consignments have unloaded horses in a number of stables across the country and in some cases these have already infected resident horses. The index cases in these consignments had not been vaccinated. Swedish veterinary authorities are now strongly recommending that buyers/importers demand vaccination before shipping and unvaccinated horses receive at least two doses of a primary course of EI vaccination. In addition, it is recommended that animals are also quarantined for a minimum of three weeks after arrival and Swedish horse owners are currently being recommended to update vaccination in active horses if more than six months has passed since their last vaccination.




The Florida Department of Agriculture and Consumer Affairs have confirmed strangles on one premises in Collier County and another in Marion County.  In both instances, only one horse was involved.  The premises in Collier County was placed under quarantine on 8 February following a positive diagnosis of strangles in a horse that first exhibited clinical evidence of the disease on 4 February, shortly after arriving from a Louisiana kill pen.  There are no other horses on the premises.


On 7 February, a premises in Marion County was placed under quarantine after a horse presented with clinical signs of strangles.  So far, this is the only case of the disease out of a total of 27 horses on the premises.
