URGENT MEDICAL WARNING: The information in this article is for educational purposes. Once symptoms of rabies begin, the disease is nearly always fatal. If you have been bitten or scratched by an animal, DO NOT WAIT FOR SYMPTOMS. Seek Post-Exposure Prophylaxis (PEP) immediately, as it is nearly 100% effective at preventing the disease.
Rabies is a preventable viral disease, but it is one of the deadliest if left untreated. Understanding its symptoms is crucial, not for self-diagnosis, but to comprehend the absolute necessity of immediate medical intervention after any potential exposure. This guide explains the progression of the disease.
The Incubation Period: The Silent Window of Opportunity

After a bite from a rabid animal, the rabies virus does not cause immediate symptoms. There is an incubation period, which is the time it takes for the virus to travel from the bite wound to the central nervous system. This period can vary widely, from a few weeks to several months (the average is 1-3 months).
This “silent” window is the only time for effective intervention. During this phase, Post-Exposure Prophylaxis (PEP) can stop the virus in its tracks.
The First Signs: Early (Prodromal) Symptoms of Rabies
The first signs of rabies in humans are dangerously non-specific and can easily be mistaken for the flu. This is why you must never wait for them to appear.
The early rabies symptoms in humans include:
- General symptoms like fever, headache, and fatigue.
- Nausea and vomiting.
- The Telltale Sign: A very specific sensation of pain, tingling, itching, or numbness at the site of the original bite wound, even if it has already healed.
The Acute Neurological Phase: The Point of No Return
Once the rabies virus reaches the brain and spinal cord, it causes severe inflammation (encephalitis) and the acute neurological phase begins. At this stage, the disease is considered fatal. The symptoms progress in one of two ways.
Furious Rabies (approx. 80% of cases)
This is the classic form of what rabies looks like in humans. Symptoms include:
- Agitation, aggression, and confusion.
- Hyperactivity and hallucinations.
- Hydrophobia: Not a fear of water, but painful, involuntary spasms of the throat muscles when trying to swallow, often triggered by the sight of water.
- Aerophobia: Spasms triggered by a draft or puff of air on the skin.
Paralytic Rabies (approx. 20% of cases)
This form is less dramatic but equally fatal. It’s characterized by muscles gradually becoming paralyzed, a process that typically starts at or near the site of the bite. The paralysis slowly ascends through the body over several days, eventually leading to a coma and death from respiratory failure.
The Inescapable Conclusion: Prevention is The Only Cure

The single, most important fact to understand about rabies is this: the only ‘treatment’ is the Post-Exposure Prophylaxis (PEP) that you receive BEFORE any symptoms begin. There is no cure once the disease takes hold.
If you have been bitten or scratched, no matter how long ago, it is not too late to seek a medical consultation. Contact a doctor immediately to discuss your situation and the possibility of receiving Post-Exposure Prophylaxis (PEP).
Conclusion
Do not gamble with your life. If there is any chance you have been exposed to rabies, act now. Prevention through PEP is your only safe option.

If you have been bitten or scratched by an animal and did not receive treatment, you need to speak to a doctor urgently.
Frequently Asked questions (FAQ) about Human Rabies Symptoms
How long after a bite can rabies symptoms start?
The incubation period varies widely, from as little as one week to over a year, but the average is 1-3 months. This unpredictable timeline is why you must not wait.
If the dog that bit me is still alive and healthy after 10 days, am I safe?
This is a common observation rule for pets in some countries. However, for a tourist in Bali dealing with a community dog whose location and health cannot be reliably monitored, this is not a safe or practical strategy. The WHO protocol is to always start PEP immediately.
What is ‘hydrophobia’ in rabies?
It is not a fear of water itself, but incredibly painful spasms in the throat muscles when attempting to swallow. The sight of water can trigger these spasms, making the patient appear to be afraid of it.
Is rabies in humans curable once symptoms start?
Once clinical symptoms of rabies appear, the disease is considered 99.9% fatal. There is an experimental treatment (the Milwaukee protocol), but its success rate is extremely low. PEP before symptoms is the only reliable way to survive.
I was bitten 3 weeks ago and now I have a fever. Could it be rabies?
While it could be rabies, it could also be a common flu or another infection. The only safe course of action is to see a doctor immediately, explain the animal bite history, and get a professional medical evaluation.
Can you test for rabies in a living person before symptoms start?
No, there is no test to determine if a person is in the incubation period. This is why PEP is administered based on the risk of the exposure, not based on a test.
My bite has already healed. Am I still at risk?
Yes. The external wound healing has no bearing on whether the virus has entered your nervous system. You are still at risk until you have completed a course of PEP.
I’m terrified. What are the actual chances of getting rabies from a bite in Bali?
The risk of any single animal being rabid is statistically low. However, the consequence of that low-risk event is death. This is why the medical community treats every potential exposure with the utmost seriousness.
I was bitten a year ago and never got shots. Is it too late to see a doctor?
It is never too late to have a medical consultation. A doctor can discuss your specific case, the nature of the bite, and provide advice based on your unique situation, even if a long time has passed.
Is there pain when the final symptoms appear?
The final stages of the disease, involving paralysis and coma, are a devastating neurological illness. The focus of all medical efforts is to ensure no one ever has to experience this through timely and effective Post-Exposure Prophylaxis.
