Why is rabies always difficult to cure?

Because rabies virus belongs to the genus Rabies virus in the family Rhabdoviridae. This viral protein has strong immunity, and in the process of the virus spreading from the bite site into the central system, various immune cells in the body cannot play any effective role in resisting the virus.

Because the rabies virus has a strong affinity for the nervous system, the virus has a certain incubation period and the incubation period can vary from a few days to 20 years. To this day, neither Chinese medicine nor Western medicine has an effective method for rabies during attacks. The reason is very simple, because the virus has invaded the brain during the attack, because the powerful affinity virus will cause great damage to the central nervous system, and our body can not produce effective antibodies, plus due to the particularity of the central nervous system, almost a dead nerve cell is one less nerve cell, and under the destruction of the virus, the nervous system cannot be repaired at all.

Therefore, once the important functional areas of the central nervous system are destroyed, the person will die immediately. Even if we can allow immune cells to be produced in the central nervous system, then this immune effect is also fatal to people.

In addition, because the course of the disease is very short, only about 6 days from the onset of symptoms to death, and the longest is only about 10 days, and it only takes 24 hours for the virus to enter the brain and completely destroy the nerves, and there is no agent that can destroy the virus and repair the nerves in a way that does not damage the central nervous system in a few days, which is why rabies patients almost certainly die once they get sick.

There are many rabies experts who have long been committed to using neuroprotection to avoid rabies, which is an important direction for overcoming rabies for the protective nature of the nervous system of rabies patients, and this protective effect has a certain effect, but the efficacy of this method is not very good. Because human nerve cells often do not have the ability to "regenerate", it is difficult for the nervous system damaged by the virus to be restored to its integrity through some means.

Therefore, rabies is very difficult to be a**.

The fatality rate of rabies is 100%, and the virus has a strong affinity for nerves, constantly destroying cells in the body, constantly expanding the virus field, and finally leading to death.

The main reason for rabies is that once the virus invades the body, it will take root in the body, so it is very difficult to get up, so after the passive bite, you must get the rabies vaccine in time.

The incubation period of rabies virus varies from a few days to as long as 20 years, and the virus has invaded the brain.

Rabies cannot be cured, and the current level of medicine cannot ** rabies. Once the disease occurs, the mortality rate is almost 100 percent. The rabies virus spreads very quickly, and antibody production cannot keep up with the speed of the rabies virus.

Rabies can be prevented, but it can't. Judging from the current level of medicine, rabies cannot be cured, and rabies has always been a medical problem. The rabies virus spreads very quickly, so the damage to various organs is relatively large, once the disease occurs, the chance of survival is very small, even if there are cases of rabies survival in the United States, but the patient still has a lot of ** diseases after surviving, so if you have rabies, the mortality rate is infinite close to 100%.

Because the rabies virus spreads very quickly, from the initial symptoms of the patient to the death of the patient, the fastest time is about five days, and the slower one will not exceed ten days, and the rabies virus enters the human brain to destroy the central nervous system and even takes only 24 hours, but the antibodies injected with rabies vaccine are generally formed gradually after 7-9 days, so the speed of antibody generation cannot catch up with the speed of rabies virus spread, so if the patient has become ill, and then inject the vaccine, there is basically no effect. Therefore, rabies can be prevented, but it cannot be prevented.

Rabies virus is a phabdovirus, which is a virus that erodes the central nervous system of humans, so the virus will quickly invade the local tissues, surrounding nerves, spinal cord and brain of humans in the body. The brain is the central nervous system, and once the brain is damaged, it causes irreparable damage to humans.
