What are the symptoms of rabies after a dog bite? - briefly
The initial symptoms of rabies after a dog bite may include pain or discomfort at the site of the bite, as well as fever and headache. As the disease progresses, more severe neurological symptoms such as hallucinations, paralysis, and hydrophobia (fear of water) can develop.

Rabies is a viral disease that affects the nervous system and is almost always fatal once symptoms appear. After being bitten by a dog, especially if the dog is suspected or known to be infected with rabies, it's crucial to recognize the early signs and symptoms of the disease.
The incubation period for rabies can vary greatly, ranging from a few days to several years, but it typically lasts around 2-3 months. During this time, the virus travels from the bite wound along the nerves to the brain. The first symptoms of rabies are usually nonspecific and may include fever, headache, muscle aches, loss of appetite, fatigue, and nausea. These early symptoms can be mistaken for other illnesses, making it difficult to diagnose rabies at this stage.
As the disease progresses, more specific neurological symptoms begin to appear. These can include:
-
Hydrophobia: This is one of the most characteristic symptoms of rabies. It refers to a fear of water and difficulty swallowing, which can lead to intense anxiety and panic when attempting to drink or even seeing water.
-
Photophobia: Similar to hydrophobia, photophobia involves an extreme sensitivity to light. Exposure to bright lights can cause discomfort and pain.
-
Paralysis: Rabies can cause paralysis that begins at the site of the bite and spreads throughout the body. This may start as weakness or numbness in the affected limb, eventually leading to complete paralysis.
-
Agitation and Aggression: Changes in behavior are also common. Patients may become agitated, anxious, or even aggressive. They might exhibit erratic behavior and have difficulty sleeping.
-
Hallucinations: Visual and auditory hallucinations can occur as the virus affects the brain. Patients may see or hear things that are not real.
-
Salivation: Excessive salivation, often referred to as "foaming at the mouth," is another well-known symptom of rabies. However, this does not always occur and should not be relied upon for diagnosis.
-
Respiratory Issues: As the disease advances, patients may experience difficulty breathing due to paralysis of the respiratory muscles. This can lead to death from respiratory failure.
If you or someone else has been bitten by a dog and there is any suspicion that the dog might be infected with rabies, it is essential to seek medical attention immediately. Early treatment, including post-exposure prophylaxis (PEP), can prevent the development of symptoms and save lives. Vaccination and sometimes immunoglobulin administration are critical components of PEP.
In conclusion, recognizing the early and late symptoms of rabies is vital for timely intervention. If you experience any of these symptoms after a dog bite, consult a healthcare professional without delay.
