Tell me about rabies.

Rabies virus can affect the nervous system, thus causing damage to the brain and spinal cord, and even leading to death in severe cases. Speaking of rabies, most people know that once infected, the mortality rate is very high, so you must stay away from stray animals when walking on the street at ordinary times to avoid being suddenly attacked. No, a black mad dog raided many residents in Nantong, Jiangsu. The monitoring screen shows that a black dog suddenly jumped out of a shop, jumped up and attacked a passerby, and then the black dog escaped. After the black dog escaped, it bit many people, including 2 1 person, all of whom were bitten to varying degrees, ranging in age from 73 to 3.

This black dog also appeared in different areas, causing panic among local residents. After more than ten hours of searching, the mad dog was finally caught. It's really scary to see such news. Dogs that bite wildly will definitely carry the virus, so if the bitten people don't get rabies vaccine in time, the consequences will be unimaginable. So how terrible is this rabies virus? Let me briefly talk about it.

What is rabies virus? Rabies virus is one of the viruses with the highest mortality. According to medical data, its mortality rate is even as high as 100%, which means that once infected, it is an incurable disease. It is also a complex virus, called rhabdoviridae rabies virus, also known as neurotropic virus, so once infected, all nerve tissues in the human body will be infected, leading to death. It should be emphasized here that rabies virus not only resides in dogs, but also exists in cats, bats, wolves and other animals. However, the transmission rate of dogs is the highest, and you should seek medical advice in time regardless of being bitten or scratched by various animals.

There are three stages of incubation period: rabies also has incubation period. When a person is bitten, the skin and muscles are infected first, but it is not fatal at this time. However, after a period of continuous invasion and replication, the virus slowly invaded the nervous system and formed reverse transportation. At this time, the damage to motor nerves and brain is the most serious, and at this time, human immunity can no longer bear such damage. So once it successfully invades the brain, all the nervous systems in the human body will be destroyed.

Symptoms: Once rabies virus comes on, the most obvious symptom is that it is afraid of light and water, and at the same time it is extremely sensitive to sound. This is because all the nervous systems in the mouth have been destroyed, especially the respiratory function and swallowing area. Therefore, when the infected person is stimulated by the outside world, the infected person's throat will spasm, which will induce dyspnea and eventually suffocation.

Paralysis: The biggest reaction during paralysis is insanity and delirium. During the onset, breathing and heartbeat will accelerate, so the infected person will be very excited and will attack others. But this phenomenon will appear for three to five days at most, and then the nervous system will gradually strike. Then there was delayed paralysis of organ failure and eventually death. Once rabies attacks, it indicates the arrival of death, so when the infected person has a binocular convergence (fierce eye) reaction, he will soon die.
