Xiao Li and her daughter were playing in the park, and her daughter was bitten by a puppy that suddenly appeared. Seeing that the dog had bitten blood on her daughter's calf, Xiao Li knew that she could not delay, and immediately picked up her daughter and went to the nearest hospital to be vaccinated against rabies. Many people may think that if they were bitten by a puppy, they couldn't tell it was a mad dog, and they couldn't get rabies, so why are they so nervous! If you don't know the fatality rate of rabies, how do you know that this is a gamble that you can't lose. The fatality rate of rabies is as high as 99%. Once infected and not vaccinated, a large proportion of rabies will die.

Why is the fatality rate of rabies so high?

Rabies virus is a kind of "neurotropic virus". When viewed under a high-power microscope, it looks like a bullet-shaped, multi-faceted oval virus. "Neurotropic Virus" is a type of virus that specifically attacks the nerves of the brain. The brain is the most important central control center of the human body. The internal organs of the body, the walking, sitting and lying, all need to be controlled by the brain.

Once the rabies virus is infected by the virus and successfully reaches the central system, the organs of the whole body will fail due to the chain effect, and the fatality rate is extremely high.

Not only that, the attack speed of rabies virus infection is very fast, it can take human life in about 1 to 3 days, and there is no time for rescue and treatment, which is also the reason for the high fatality rate of rabies.

Professor Persson, a scientist at Tel Aviv University, once led a research team to dissect the body and brain of rabies deceased in order to decipher the truth of the high mortality rate of rabies.

Researchers reveal the real death process of rabies

According to the results of the study, after the brain of the rabies deceased was cut open, it was found that a large number of blood vessels in the brain were damaged and covered with purple necrotic tissue, which means that the virus spreads quickly, and the brain has no time to repair itself. At the same time, the muscles of the limbs of the deceased also had varying degrees of necrosis.

Further research by the research team found that the reason why the rabies virus has such a high fatality rate is that the virus DNA has been infected with some nerve growth factors, which spread the virus through the transmission of the nervous system, and spread from the brain to the whole body, which accelerated the spread of the virus and caused death.

The conduction speed of neurons is theoretically faster than that of a high-speed fighter jet, which is equivalent to the thinking speed of our brain. With such a high-speed virus spread, it is conceivable that there will be such a high fatality rate.

It can be seen that the 99% fatality rate of rabies virus requires us to be more vigilant about this virus. If you are accidentally bitten by a dog, it is very important to understand the relevant first aid knowledge and deal with it in time.

Keep in mind that after being bitten by a dog The "Golden Three Steps" of First Aid

Step 1: Immediately clean the wound

After being bitten, if it is an individual carrying rabies virus, no matter the size, its blood and saliva will contain a lot of rabies virus. So the first time to clean the wound in time. It can be washed with plenty of water, preferably with diluted alcohol or soapy water, which can effectively reduce the invasion of rabies virus.

Step 2: Injection of immune serum

If the wound is close to the brain and the neck is close to the brain, it is best to inject the immune serum in time. Generally speaking, the injection dose is about 40IU/KG for about five days in a row to achieve the purpose of quickly hindering the spread of the virus and reducing the rabies virus. Risk of emergency spread.

Step 3: Vaccination

Vaccination within 24 hours of being bitten by an animal is the top priority of first aid and is the most effective against potential rabies virus.

On the third day, one week, two weeks, and one month after vaccination, it is necessary to adhere to multiple rounds of vaccination to ensure their own safety.

All in all, rabies virus is very dangerous, we must keep in mind and implement the three-step first aid measures, rational response, active treatment, most of the risks can be avoided, so as to prevent rabies from infringing our lives.
