I would just like to say that the disease can take up to 21 days from exposure to start showing symptoms so any quarantine should be done for at least 3 weeks - closer to 4 to be safe. The disease can also travel through the air.
Virkon is about the only thing that will kill the virus and it is cheap and easy to use. Wouldn't hurt to disinfect your stall :)
Good luck to everyone affected!!!
