Rabies, also known as hydrophobia, is an acute infectious disease of natural zoonosis caused by the rabies virus. The epidemic is widespread and the mortality rate is extremely high, almost 100%.

It poses a serious threat to people's life and health. Rabies is usually transmitted to humans through bites from infected animals. The clinical manifestations include unique fear of water, fear of sound, fear of wind, fear and anxiety, pharyngeal muscle spasm, progressive paralysis, etc.

The clinical manifestations of rabies can be divided into four stages.

1. Incubation period: The incubation period varies in length, with the shortest being 3 days and the longest being 19 years, and the average is generally about 20-90 days. During the incubation period, the infected person does not have any symptoms.

2. Prodromal stage : The infected person begins to experience general discomfort, low fever, headache, nausea, fatigue, followed by fear, anxiety, irritability and insomnia, and is sensitive to sound, light, wind and other stimuli and has a feeling of tightness in the throat. There are symptoms such as itching, pain, numbness, tingling and other abnormal sensations in the healing wound and its nerve supply area. This phase lasts 2-4 days.

3. Excitement stage : manifested as high excitement, with prominent features such as extreme fear expression, fear of water and fear of wind. Elevated body temperature (38-40 degrees) and hydrophobia are the characteristics of this disease, but not in every case. Although typical patients are extremely thirsty but dare not drink, seeing water, hearing the sound of water, drinking water, or just mentioning drinking water can cause severe spasm of the pharyngeal muscles. External stimuli such as wind, light, and sound can also cause pharyngeal muscle spasms, which may cause hoarseness, slurred speech, and ventilator spasms may cause breathing difficulties and cyanosis. Sympathetic nervous system hyperactivity can be manifested as profuse sweating, increased heart rate, and increased blood pressure. However, the patient is usually conscious, but may experience mental disorders and hallucinations. This issue is 1-3 days.

4. Paralysis stage: If the patient manages to survive the excitement stage, he or she will enter the coma stage. During this stage, the patient is in a deep coma, but the various symptoms of rabies are no longer obvious. Most patients who enter this stage eventually die of exhaustion. Patients often suffocate to death due to spasms in the throat.

Because the harm caused by rabies is extremely great and can even affect life and health, for modern people, once they are bitten by cats or dogs, they must be vaccinated with rabies vaccine in time to maximize the effect of rabies vaccination and stay away from the nuisance of rabies.
