What happens to animals infected with rabies?

Animals infected with rabies undergo several physiological and behavioral alterations as the virus affects the central nervous system and the brain. The progression of rabies in animals typically involves various stages:

1. Incubation Period: The incubation period for rabies can vary from a few days to several months. During this time, the virus is replicating and spreading through the nerves, but the animal may not exhibit any noticeable symptoms.

2. Prodromal Stage: Early symptoms of rabies may include behavioral changes such as restlessness, irritability, and anxiety. The animal may become withdrawn or shy and may have a decreased appetite.

3. Furious Rabies: This stage is characterized by hyperactivity, aggression, and violent behavior. The animal may attack anything in its vicinity, including humans and other animals. Hydrophobia, or a fear of water, is also a common symptom. Animals with furious rabies may have difficulty swallowing, drool excessively, and produce unusual vocalizations.

4. Paralytic Rabies: This variant of rabies is less common and is characterized by progressive paralysis. The animal may experience muscle weakness and coordination issues, leading to difficulty walking or standing. Paralysis eventually affects the respiratory muscles, causing difficulty breathing and eventually death.

5. Death: Untreated rabies is almost always fatal. The infection can progress rapidly, leading to death within a few days to a few weeks after the onset of symptoms.

Overall, rabies in animals poses a significant risk to both human and animal health. Early detection and prompt medical attention are crucial for preventing the spread of rabies and protecting both people and animals from this fatal disease.
