How does the rabies virus infect humans?

When it comes to rabies, everyone talks about it, it is a malignant infectious disease with strong transmissibility and poor prognosis. We all know that if you get rabies, the patient will have mental problems and eventually die of organ failure. So what is the process of the rabies virus infecting the human body?

Let's take a look.

Extraneural minimum. This is what we usually call the incubation period, where the virus invades from the bite site, first multiplies in small amounts in the cells here, and by combining with certain cells in the body, it infiltrates nearby peripheral nerves for a short period of time, up to three days. At this time, there are no symptoms of infection.

Invasion of the central nervous system from peripheral nerves. There is a prodromal phase, when the virus will spread centripetally along the surrounding nerves, and then after hitting the ganglia, it will begin to multiply in large numbers, invade the bone marrow, and then spread to the entire central nervous system. At this time, if you get a vaccination, you can stop its vicious spread.

From the central nervous system to the period of diffusion to various organs. At this time, the virus spreads outward centrifugally and enters various tissues and organs. At this time, the infected person will have physical discomfort, low-grade fever, headache, nausea, fear of sound, light, wind, etc.

It causes the patient's cardiovascular system to malfunction, although the patient is conscious at this time, but has mental disorders and the patient appears.

Finally, there is the paralysis phase. However, most patients who enter this stage eventually fail and die. The incidence is also related to the location of the bite, and if the bite is on the head, face, and arms, the incidence is high. If the bite is deep, the incidence is also high.

After understanding the pathogenesis of rabies, I believe that everyone has a clearer understanding of the process of rabies invasion into the human body. Therefore, we must actively prevent rabies, and hope that friends will inject their dogs with rabies vaccines to avoid serious consequences for those who are infected with the virus.

After the rabies virus infects the human body, it will not attack immediately, there is a certain incubation period, and the incubation period of each person is different, once the fatality rate of the attack is more than 99, there are almost no cases.

Dogs with rabies virus, generally speaking, belong to this kind of stray dogs in the wild, this kind of dog has the possibility of rabies virus on its body, it is far more likely than this kind of domestic dog in their own home, it is much more likely to carry the virus, especially this kind of stray wild dog only draft, and other wild animals have more opportunities to contact, and it is in the wild environment, long-term growth at such a stage, the chance of exposure to this rabies virus is much more.

However, some family dogs sometimes go out and may come into contact with these stray cats and dogs outside, which may also carry the rabies virus.

Pay attention to things: If you are bitten by a dog, regardless of whether the dog shows symptoms or not, it is still recommended to go to the hospital in time to get vaccinated according to the doctor's advice. Usually dogs infected with rabies virus and in the onset period will show obvious neurological symptoms, such as dull eyes, salivation, return and rabies is also known as hydrophobia, so dogs infected with the virus will have obvious panic about the water performance, and dogs infected with rabies are very emotionally unstable and aggressive.

Rabies virus is generally found in animals, such as dogs, cats, pigs, cattle, etc. The rabies virus can be transmitted by animals, and the main forms of transmission are bites, contacts, etc., which should cause vigilance.

1.Bites. If you are accidentally bitten by an animal infected with rabies virus, the virus will enter the human body through the wound and cause the human body to be infected with rabies virus, so it is usually recommended not to touch the animal outside.

2.Contact. If the patient comes into contact with rabies, and there is a ** injury at the contact site, the rabies virus may enter the body through the injury site and cause rabies virus infection, it is recommended not to have close contact with the animal when there is ** damage on the body.

In addition, the fatality rate caused by rabies infection is nearly 100%, and there is no good method, if the above situation, it is recommended to go to the hospital for rabies virus vaccination in time to prevent rabies.

Rabies is an acute infectious disease caused by rabies virus infection. If you think there is a chance of contracting the disease, you must complete the injection within 24 hours of the event. However, there are exceptions.

Some people get delayed because of something. They went to the hospital to get the injections done before they got sick or had uncomfortable symptoms, and everything was fine.

Rabies is an acute infectious disease caused by infection with rabies virus.

Both humans and animals can suffer from this disease. Animals are generally more common in carnivores such as dogs, cats, and wolves. Humans are usually infected because they are scratched and bitten by sick animals.

Clinical manifestations include: fear of water, fear of wind, pharyngeal masseter muscle spasm, progressive paralysis, etc.

Rabies is an acute infectious disease caused by infection with rabies virus.

Rabies in China is mainly transmitted through dogs, and domestic dogs are one of the asymptomatic carriers. In other words, dogs that look normal on the surface are also harmful to human health. Therefore, as long as you are bitten by a dog, you must be vaccinated against rabies.

At present, there is no effective way to ** this disease. Therefore, if a person has rabies, the mortality rate can be as high as 100% if measures are not taken in time. Patients die from respiratory and circulatory failure within 3 to 7 days of infection, so precautions must be strengthened.

Rabies is an acute infectious disease caused by infection with rabies virus.

After the human body is damaged by the protective layer of the diseased animal, the virus present in the saliva of the animal can enter the body through the wound site, destroy the relevant cells, and cause disease. In a small number of patients, conjunctivitis is caused by saliva infection in diseased animals. Infected people may not all get sick.

It occurs in about 15% to 20% of patients bitten by sick dogs but not vaccinated, and in about 50% to 60% of patients bitten by sick wolves. Risk factors for rabies include: location of the bite, severity of the wound, condition of the wound, thickness of clothing, and whether the vaccine is administered in a timely manner.

Rabies is usually transmitted by a dog or cat with rabies virus, and it is still very scary.

The most common mode of transmission of rabies is through liquids, such as bites or scratches by animals such as cats and dogs.

Rabies is mainly caused by contact with broken ** to invade the subcutaneous nervous system, and then slowly enter the central nervous system along the subcutaneous nervous system.

The route of rabies virus infection is mainly due to the open wound coming into contact with the infected saliva and is infected, and, with the current medical technology, it is not effective for dogs or people infected with rabies virus**, and can only be prevented by vaccine.

Dogs are infected with rabies virus. jpg"/>

The dog is infected with rabies.

1. Symptoms of rabies virus infection in dogs.

When a dog is infected with rabies virus, it will behave differently from usual, such as liking to hide in a dark environment, hating places with light, changing temper, being extremely irritable, biting, and scurrying, it is infected with rabies.

Poisoned. The shovel officer is about to pay attention.

2. How long can dogs live if they are infected with rabies virus.

Generally speaking, the incubation period of rabies virus in dogs is kept within 14 days, and the longest will not exceed two months, however, once the attack starts, the dog will die within 10 days, and the chance is almost 0.

Once you find that your dog has symptoms of rabies virus, the shovel officer should pay attention to it and isolate the dog in time to avoid being bitten by the dog. To regularly inject dogs with rabies vaccination, pay attention to choose a formal pet institution for injection. If you are bitten by a dog, you should immediately disinfect it and get a rabies vaccination.
