What is prodromal phase of rabies?
Rabies is a fatal infection, which usually progresses over 2 – 21 days. A prodromal phase, lasting 2 – 10 days, is characterized by pain and numbness/tingling at the site of the bite (present in 50\% – 80\% of cases), and nonspecific complaints such as fatigue, headache and fever.
What are the four stages of rabies?
Rabies virus causes acute infection of the central nervous system. Five general stages are recognized in humans: incubation, prodrome, acute neurologic period, coma, and death. The incubation period is exceptionally variable, ranging from fewer than 10 days to longer than 2 years, but is usually 1–3 months.
What are four 4 symptoms an animal may have rabies?
Signs progress within days to cerebral dysfunction, cranial nerve dysfunction, ataxia, weakness, paralysis, seizures, difficulty breathing, difficulty swallowing, excessive salivation, abnormal behavior, aggression, and/or self-mutilation.
What are the 3 stages of rabies?
There are three clinical phases of the disease:
- Prodromal phase – the onset of clinical rabies in man includes 2-4 days of prodromal.
- Excitation phase – the excitation phase begins gradually and may persist to death.
- Paralytic phase – hydrophobia, if present, disappears and swallowing becomes possible,
What are prodromal symptoms?
Prodrome is a medical term for early signs or symptoms of an illness or health problem that appear before the major signs or symptoms start. Psychosis, a group of symptoms found in disorders like schizophrenia, is one illness with a specific prodrome.

How long does it take for rabies symptoms to show up?
Most of these signs are obvious to even an untrained observer, but within a short period of time, usually within 3 to 5 days, the virus has caused enough damage to the brain that the animal begins to show unmistakable signs of rabies.
How long does the incubation period for rabies last?
This time between the exposure and the appearance of symptoms is called the incubation period, and it may last for weeks to months. The incubation period may vary based on the location of the exposure site (how far away it is from the brain), the type of rabies virus, and any existing immunity.
Why is the time between exposure to rabies and onset so variable?
The reason there is so much variation in the time between exposure and the onset of the disease is that many factors come into play, including the site of the exposure, the type of rabies virus, and any immunity in the animal or person exposed. The Infectious Path of the Rabies Virus. An animal is bitten by a rabid animal.
How long does it take for rabies to spread in dogs?
Rabies virus from the infected saliva enters the wound. Rabies virus travels through the nerves to the spinal cord and brain. This process can last approximately 3 to 12 weeks.
