Which observable sign in animals should raise suspicion of rabies to an ACO?

• A. Sudden aggressive behavior or fearlessness
• B. Uncharacteristic approach to humans
• C. Excessive drooling
• D. Stumbling or paralysis

Answer: (A)

Rabies alters the brain and drives dramatic changes in behavior. The most important observable sign for an ACO is a sudden shift to aggression or fearlessness in an animal that would normally avoid people. This abrupt, hyperactive or uninhibited behavior is a hallmark of furious rabies and signals a high risk that the animal is infected, so it should trigger immediate safety measures and reporting. Other signs like excessive drooling, stumbling, or an uncharacteristic approach to humans can occur with rabies but are less specific and can result from many other conditions. Drooling can happen because the virus affects swallowing, but it isn’t unique to rabies; stumbling or paralysis can appear later in the disease or from other illnesses; an animal approaching humans can occur for reasons other than rabies. The standout sign, therefore, is the sudden aggressive or fearless behavior, because it most reliably indicates a potential rabies infection and prompts appropriate precautions.
