Which of the following animals must be quarantined if they have bitten a person?

The correct answer indicates that all domestic animals must be quarantined if they have bitten a person. This is primarily due to the public health implications associated with bites, particularly concerning the transmission of zoonotic diseases such as rabies.

When a domestic animal, such as a dog, cat, or even a domesticated farm animal, bites a human, there is a need to ascertain the animal's health status, especially its vaccination history for rabies. The quarantine period allows for monitoring the animal for any signs of illness and ensures the safety of the community.

While wild animals can also pose risks if they bite humans, the focus here is specifically on domestic animals, which are more likely to come into contact with people. Quarantining all domestic animals helps in gathering essential health data and allows authorities to manage public health safety effectively.

In contrast, the other options limit the scope to only certain types of animals, which does not capture the comprehensive approach taken in animal bite cases. The regulation regarding quarantine applies to all domestic species due to their interaction with humans and the potential health risks involved.
