Do Rabies Symptoms Come and Go? Exploring the Fluctuating Nature of this Deadly Disease
No, rabies symptoms generally do not come and go. Once clinical signs of rabies appear, the disease is almost invariably fatal, and the progression is typically relentless, although there might be perceived fluctuations in severity due to the complex neurological impact.
Understanding Rabies: A Deadly Viral Disease
Rabies is a zoonotic disease caused by the rabies virus, primarily transmitted through the saliva of infected mammals. While preventable with prompt post-exposure prophylaxis (PEP), rabies is nearly always fatal once symptoms manifest. The virus attacks the central nervous system, leading to a range of neurological symptoms. Understanding the different stages of rabies is crucial to grasping why symptoms are largely considered non-remitting. It’s important to reiterate, however, that what appears to be a symptom coming and going may be due to the disease’s complex impact on the brain, rather than the symptom actually disappearing and returning.
The Stages of Rabies Infection
Rabies progresses through distinct stages, each characterized by specific symptoms:
-
Incubation Period: This initial phase can last weeks to months, even years in rare cases. During this time, the virus is replicating silently within the body, with no noticeable symptoms. The length of incubation depends on factors such as the location of the bite and the amount of virus introduced.
-
Prodromal Stage: The first signs of rabies begin to appear, often mimicking flu-like symptoms. These include:
- Fever
- Headache
- Malaise (general feeling of discomfort)
- Pain or itching at the site of the bite
These symptoms usually last 2 to 10 days.
-
Acute Neurological Phase: This is when the classic symptoms of rabies become evident. There are two main forms: furious rabies and paralytic rabies. In furious rabies, the infected individual may exhibit:
- Agitation
- Anxiety
- Confusion
- Hydrophobia (fear of water) – caused by painful spasms in the throat when trying to swallow.
- Aerophobia (fear of drafts or fresh air)
- Seizures
- Hyper-salivation (excessive saliva production)
- Bizarre or aggressive behavior
In paralytic rabies, which accounts for about 20% of human cases, the dominant symptom is a gradual paralysis that starts at the bite site and spreads throughout the body. While less overtly dramatic than furious rabies, it is just as deadly. Both types eventually lead to coma and death.
-
Coma and Death: Regardless of the form, once the acute neurological phase progresses significantly, the affected individual typically enters a coma, eventually succumbing to respiratory failure or other complications.
Why Symptoms Appear to Fluctuate (But Don’t Actually Go Away)
Although the progression of rabies is generally linear, some symptoms may appear to fluctuate in intensity. This perceived change is primarily due to the virus’s erratic impact on different parts of the brain. For instance:
- Neurological Chaos: The rabies virus affects various regions of the brain at different rates. This can lead to periods of relative calm followed by episodes of intense agitation, confusion, or seizures. This variability does not mean the symptoms are disappearing; it reflects the uneven spread of the virus.
- The Role of Medication: In rare cases where supportive care is provided in an attempt to manage symptoms, medications like sedatives might temporarily mask or reduce the severity of some symptoms. However, this does not alter the underlying progression of the disease.
Why Prompt PEP is Crucial
Because rabies is virtually untreatable once symptoms appear, post-exposure prophylaxis (PEP) is critical. PEP involves a series of rabies vaccinations and, in some cases, rabies immunoglobulin (RIG). The goal of PEP is to prevent the virus from reaching the brain and causing clinical disease. It is highly effective when administered promptly after exposure. Knowing the nature of rabies and the importance of immediate action are key to survival.
Key Takeaways Regarding Rabies and Symptom Fluctuation
| Key Concept | Explanation |
|---|---|
| Irreversible Progression | While intensity may vary, established rabies symptoms do not genuinely remit. |
| Brain Damage | Fluctuations in symptom presentation are generally linked to the chaotic nature of viral spread and damage within the brain. |
| Prompt Action | Post-exposure prophylaxis (PEP) is essential for preventing the onset of rabies. Seek medical attention immediately after any potential exposure. |
Debunking Myths About Rabies Symptoms
It’s crucial to dispel any misconceptions about rabies symptoms and their potential to resolve on their own. Many online resources contain misinformation about rabies, leading to unnecessary fear or false hope. Remember, rabies is a serious and deadly disease that requires immediate medical attention. Delaying treatment in the hope that symptoms will subside is a grave mistake.
Do Rabies Symptoms Come and Go? Seeking Clarity and Accurate Information.

Frequently Asked Questions (FAQs)
Can rabies symptoms disappear on their own?
No, rabies symptoms do not disappear on their own. While the intensity of certain symptoms might fluctuate, this does not indicate that the disease is resolving. It is a reflection of the complex neurological damage caused by the virus.
What are the very first symptoms of rabies?
The initial symptoms of rabies are often nonspecific and flu-like. They may include fever, headache, malaise, and pain or itching at the site of the bite. These early symptoms can make diagnosis challenging.
Is there any treatment for rabies once symptoms appear?
Unfortunately, there is no effective treatment for rabies once clinical signs develop. The disease is almost invariably fatal. Supportive care may be provided to alleviate suffering, but it cannot cure the infection.
How long can the incubation period for rabies last?
The incubation period for rabies can vary widely, ranging from weeks to months, and even years in very rare cases. The average is typically between 1 and 3 months.
What animals are most commonly associated with rabies?
In the United States, the animals most commonly associated with rabies are bats, raccoons, skunks, and foxes. However, any mammal can potentially carry the virus.
What should I do if I am bitten by an animal that might have rabies?
If you are bitten by an animal that might have rabies, immediately wash the wound thoroughly with soap and water. Then, seek prompt medical attention to receive post-exposure prophylaxis (PEP).
Is rabies preventable?
Yes, rabies is highly preventable with prompt post-exposure prophylaxis (PEP). The sooner PEP is administered after a potential exposure, the more effective it is.
Can rabies be transmitted through the air?
While rare, airborne transmission of rabies has been documented in very specific environments, such as caves inhabited by large colonies of bats. This is not a typical route of infection for humans.
How is rabies diagnosed in humans?
Diagnosing rabies in humans can be challenging, especially in the early stages. Diagnostic tests may include saliva samples, skin biopsies, and cerebrospinal fluid analysis. Often, diagnosis is confirmed post-mortem.
What is the Milwaukee Protocol?
The Milwaukee Protocol is an experimental treatment for rabies that involves inducing a coma in the patient and administering antiviral medications. It has had limited success and is not a standard treatment.
Is there a vaccine for rabies for humans?
Yes, there is a safe and effective rabies vaccine for humans. It is primarily used for pre-exposure prophylaxis in individuals at high risk of exposure (e.g., veterinarians, animal handlers) and for post-exposure prophylaxis.
Can a pet vaccinated against rabies still get the disease?
While rare, it is possible for a vaccinated pet to contract rabies. The vaccine is highly effective, but not 100% protective. Regular booster vaccinations are essential to maintain immunity.
