What are the symptoms of the rabies virus in humans?

Afraid of light, afraid of sunlight and light, and afraid of the sound of water.

Excitement comes from time to time.

If it is scratched by a feral cat, it is necessary to consider whether you have rabies or cat scratch fever.

Domestic cats don't need to worry too much because domestic cats are cleaner than wild cats The symptoms of rabies can be divided into: prodromal phase. Manic phase. There are three stages of paralysis.

Prodromal stage: At the beginning of the disease, children often complain of headache, restlessness, fear and other neurological symptoms, and may also have symptoms such as nausea and vomiting. Body temperature up to 37 5--38 .

The child's personality or behavior may change, such as depressed, depressed, restless, and some irritation. The bite site is red, there is stinging or numbness around the wound, there is swelling, accompanied by a feeling of ants walking and intense itching. Wound changes are an important differentiator of maniac disease and are of great help in early diagnosis.

Further, laryngeal urgency, anorexia, and dysphagia may occur. At this time, it is generally 1-3 days, sometimes it can be 7 days.

Manic phase: Also known as the euphoria phase, the unique symptoms of a rabies year, such as hydrophobia, paroxysmal mania, and salivation episodes, may occur. When the patient wants to drink water, it causes severe spasms in the pharynx, and it is difficult to breathe, which is very painful.

In the future, whenever you see or hear the sound of water, or even think of water, it can cause reflex attacks, so it is also called"Hydrophobia"。Pharyngeal spasms may also spread to the respiratory muscles, causing dyspnea, cyanosis, and dilated pupils. The patient is conscious during the interictal period, and as the paroxysmal spasms intensify, the patient becomes manic from time to time.

Due to sympathetic nervous system stimulation, the patient experienced profuse sweating and salivation, coupled with vomiting and impaired eating and drinking, and soon became dehydrated. Body temperature up to 39--40. This period lasts 1-3 days.

Paralysis stage: The patient passes the manic period and turns manic to quiet, the spasms gradually stop, the reaction is slow, and a small amount of food can be eaten, and the general family members often think that the condition is getting better. In fact, he soon developed cranial nerve and limb nerve paralysis, and eventually died due to respiratory and circulatory failure.

This period is shorter, generally 15-20 hours.

It has a long incubation period! Generally, virus carriers are afraid of light, water, sound, ......

Generally, by the time you find out, you are already terminally ill. At first, there are usually no obvious symptoms, and it is thought that the virus has a latent period.

Just carrying the rabies virus, the dog will not show obvious characteristics. When a dog has a rabies attack, it will show characteristics such as fear of water, fear of wind, and easy anger. In the later stages of the disease, the dog will also find muscle spasms, body paralysis, and difficulty breathing.

Dogs (Latin canislupusfamiliaris) belong to the phylum Chordates, Subphylum Vertebrates, Mammalia, Subclass Euzos, Carnivores, Schizopodae, Canidae. Also known as "dog" in Chinese, dogs are found all over the world. Dogs were domesticated from wolves.

As early as the hunter-gatherer era, dogs were domesticated as hunting assistants. Therefore, dogs are considered to be the earliest domesticated domestic animals of humans. Dog bones have been found in Cishan in Wu'an, Hebei, Pei Ligang in Xinzheng, Henan, and Hemudu in Yuyao, Zhejiang, which proves that it has a long history of domestication.

The dog-shaped stalk unearthed in Sanlihe, Jiaoxian County, Shandong Province has a vivid and realistic shape, allowing us to see the morphological characteristics of domestic dogs in the Neolithic Age.

Normal dogs have the same rabies virus, and you have to take good care of your pet, otherwise it will go out and bite people, which will bring you financial losses.

If a dog has been vaccinated against rabies, it is unlikely that any other dog will carry the rabies virus. For dogs with healthy appearance, relevant epidemiological investigations are carried out, and some dogs can carry rabies virus in health, and this proportion is due to the high and low animal immunity rate.

Yes.

Healthy dogs can carry the rabies virus, but the probability of carrying the rabies virus varies from region to region. If you are in a city, most of them are pet dogs, and there are fewer opportunities for contact with wild animals in the outside world, so the possibility of getting rabies virus and carrying it is very small. Pets in many cities are vaccinated against rabies, which further reduces the probability of carrying the rabies virus.

According to some statistics, in larger cities, the probability of dogs carrying rabies virus can even be zero, that is, there are no pet dogs with rabies virus detected, which is safer.

If rabies vaccination can be widely used in dogs, the transmission of rabies from dogs to humans can be further reduced or even eliminated. In rural areas with a high incidence of rabies, the carrier rate of rabies virus in healthy dogs is relatively high, according to relevant statistics, some can even be as high as about 7%, because most of these dogs do not carry out rabies vaccination, and many are free-range, and have more contact with wild animals.

Puppies do not carry the rabies virus.

Puppies will not have rabies, because rabies will not be transmitted through childbirth, so the newborn puppy will definitely not carry the virus, and the general incubation period of dogs with rabies is about 15 days and will be sick for up to 6 months, so the chance of newborn puppies getting rabies is close to zero.

Newborn puppies do not have rabies, this is because the rabies virus does not spread through childbirth, because the rabies virus does not spread vertically, so the newborn puppies will never carry the virus.

And healthy cats and dogs are not contagious to rabies. This is the authoritative statement of the World Health Organization. If licking your puppy and not dying of rabies within 10 days, you will never be able to get rabies, please rest assured.

Not necessarily.

There are still a small number of dogs with rabies virus, and the vast majority of dogs do not have rabies virus, especially domestic dogs that have been vaccinated against rabies in a standardized manner, and generally there will be no rabies virus carrying, and stray dogs on the street and dogs in rural areas may carry rabies virus if they are not vaccinated against rabies.

Dogs are not born with rabies virus, mothers and babies cannot be left with rabies, and no animals have been found to be born with rabies virus, they are all acquired, and it has been known that if the animal is not within the infectious period, you cannot be infected by biting (scratching). Healthy animals do not transmit rabies.

Provisions. Dog regulations stipulate that dogs must be vaccinated against rabies, and it is mandatory to inject rabies vaccine for dogs, which can produce antibodies in the body, which is to prevent domestic dogs from being infected with rabies bacteria and developing diseases for some reason, and effectively protect the health interests of people and dogs. For dogs with healthy appearances, relevant epidemiological investigations are conducted, and some dogs can carry rabies virus in health.

This proportion varies depending on the immunization rate of the animal. However, the corresponding survey carryover rate is not less than 10%, and most of the surveys are between 3% and 5%. However, due to the fact that once you have rabies, the mortality rate is almost 100%, so you should not be lucky after being scratched and bitten by a dog, and you should treat it accordingly in time.

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.
