What type of animal must be quarantined for 45 days if it has been exposed to rabies?

The correct choice is that a vaccinated domestic animal must be quarantined for 45 days if it has been exposed to rabies. This is based on the understanding that vaccinated animals have a lower risk of developing rabies compared to unvaccinated ones. However, even vaccinated pets can still potentially contract the virus, especially if exposed to an infected animal.

The 45-day quarantine serves as a precautionary measure to monitor for any symptoms of rabies and ensure public safety. During this period, the animal will be observed for any signs of illness, and it allows veterinary authorities to take further action if needed.

In contrast, unvaccinated pets would typically be subjected to more stringent measures, which may include euthanasia in certain jurisdictions to prevent further spread of the disease. The same is true for stray animals, which may not have an owner to monitor their health or vaccination status. Farm animals, under similar conditions, would also not follow the same protocols typically designated for vaccinated domestic pets.
