The state tightened restrictions on prairie dogs and African rodents, which spread the virus to more than three dozen Wisconsin residents.
The amended rule bans the import, sale, public contacts or release of any prairie dog or African rodent.
The rule had previously applied to any prairie dog as well as any mammal that had come into contact with prairie dogs since April first.
The new rule not only prohibits the import or sale of all prairie dogs, it also bans the import and sale of all African rodents regardless of whether they have been known to have had contact with a prairie dog.
The new regulations will remain in effect until at least November 9.
