Pre-rabies signs

Rabies is a very serious disease. It often occurs after a person is bitten by a mad dog infected with the rabies virus. At this time, people will gradually develop the disease. If the rabies vaccine is not given, there is a risk of death. There are many early symptoms of rabies, and there is a certain incubation period, which can be long or short. Then there will be a prodromal period, which will cause general discomfort, leading to fever and other symptoms, and finally the patient will enter a coma, eventually leading to the death of the patient.

Pre-rabies signs

Similar to general viral encephalitis, the most specific and diagnostically significant change is the presence of Negri bodies (eosinophilic inclusion bodies present in the cytoplasm of nerve cells in 80% of rabies patients), which are round or oval, about 3 to 10 μm in size, with neat edges and 1 to 2 small dots resembling cell nuclei inside. It is most commonly found in the pyramidal cells of the hippocampus and the Purkinje cells of the cerebellum. Negri's cells have been confirmed to be virus colonies, and electron microscopy shows that the cells contain rod-shaped virus particles. If these bodies are found in human or animal brain cells, the diagnosis can be confirmed.

1. Incubation period:

(The average is about 4-6 weeks, the shortest and longest range can be up to 10 days-8 months). The incubation period varies from a few days to several years depending on the individual's physical condition. During the incubation period, the infected person does not have any symptoms.

2. Prodromal stage: The infected person begins to experience symptoms such as general discomfort, fever, fatigue, restlessness, pain in the bitten area, and abnormal sensation.

3. Excitement period:

Humans: Various symptoms of the patient reach their peak, including mental tension, whole body convulsions, hallucinations, delirium, fear of light, sound, water, wind, etc. Therefore, rabies is also called hydrophobia. Patients often suffocate to death due to spasms in the throat.

4. Coma:

If the patient manages to survive the excitement phase, he or she will enter the coma phase. During this phase, the patient is in a deep coma, but the various symptoms of rabies are no longer obvious. Most patients who enter this phase eventually die of exhaustion.

What is rabies

Rabies is an acute infectious disease caused by the rabies virus. It can be transmitted between humans and animals, and mainly occurs in some carnivorous animals, such as dogs, wolves, cats, etc., and the most common are dogs and cats. Animals such as wolves are difficult to come into contact with in daily life, while dogs and cats have become pets that people like to keep. Therefore, dogs and cats have become the main carriers of rabies, and most people are infected due to bites from sick dogs or cats. Therefore, the best way to prevent rabies now is to make sure to get the rabies vaccine immediately after being bitten. As long as the rabies vaccine is given, the occurrence of rabies can be controlled by 90%.
