Many people think that their domestic dogs are healthy in appearance, will not carry rabies virus, and do not pay attention to prevention.

In fact, this is a big misunderstanding of rabies.

Nearly 70% of rabies patients are bitten by "healthy dogs". Epidemiological investigation shows that the carrier rate of dog virus with healthy appearance is as high as 5 ~ 10%, and the carrier rate of dog virus with suspected bite is above 30%. The seemingly healthy animals carrying rabies virus have become the most dangerous source of rabies infection.

Therefore, it is not impossible for a well-paid domestic dog to have an injection.

When domestic animals suffer from rabies, the symptoms are loss of appetite. When they saw the water, they were afraid, barking and twitching. When they come into contact with people, animals or other objects, they will bite people, and finally they will be paralyzed and die. When people suffer from rabies, the symptoms are mental disorder, nausea, salivation, water phobia, muscle spasm, difficulty breathing, and finally paralysis and death. Also known as water phobia.

There may be some sick dogs with special symptoms, but at least some of the above symptoms will appear.

Early symptoms of canine rabies

In 2005, three famous rabies experts from Thailand, Britain and WHO, Veera Tepsumethanon, Henry Wilde and Francois X Meslin, published their research papers in J Med Assoc Thailand (3): 419-22), suggesting that six criteria can be used when the conditions of the ten-day observation method cannot be fully met. The topic of this paper is six criteria for diagnosis of rabies in live dogs (full text download: six criteria for diagnosis of rabies in live dogs. pdf).

To diagnose whether a live dog has rabies, if the conditions of the ten-day observation method cannot be fully met, the following criteria can be adopted in turn:

1) How old is the dog?

A) less than 1 month-> not rabies.

Description: The incubation period of rabies in dogs is usually above 1 month, so dogs less than one month old usually don't have rabies. Moreover, it is almost impossible for a puppy born less than a month to be bitten by other mad dogs without being bitten to death. )

B) more than a month or I don't know-> enter 2)

2) The dog's health?

A) I) normal (no disease) or ii) sick for more than 10 days-> not rabies.

(Note: here I) The observation time is generally within ten days, and the principle is similar to the ten-day observation method. Ii) If the dog has been ill for more than ten days, it is definitely not rabies, because if it is not rescued, the dog will die in less than ten days.

B) start to get sick within 10 days, or get sick less than 10 days, or don't know-> enter 3)

3) How does the disease evolve?

A) acute attack of normal healthy people->; This is not rabies.

Description: The onset of rabies is usually slow at first, with a mild prodromal period of 1-3 days, and then it becomes more and more serious. )

B) gradually attack or don't know-> input 4)

4) What is the development trend in the last 3-5 days?

A) stable or improved (untreated)-> not rabies

(Note: Once rabies occurs, the general development trend is more and more serious. Especially in the later stage, the severity is irreversible. )

B) further development of symptoms and signs, or unknown-> input 5)

5) Does the dog show the action of "turning in circles"?

I often trip or walk in circles and hit my head against the wall, as if I were blind. )

A) yes-> not rabies

Description: It is a symptom of canine distemper or other diseases. )

B) no or I don't know-> input 6)

6) In the last week of life, did the dog show at least two of the following 17 signs or symptoms?

A) yes-> it's rabies

B) No, or only 1 symbol-> is displayed; This is not rabies.

1. Chin droops and looks weak (Figure 1).

2. Abnormal barking.

3. The tongue is hanging out and drooling a lot.

4. Lick your own urine.

I especially like licking water.

6. Go back to your stomach.

7. Behavior change.

8. Bite an abnormal object.

9. Aggressive behavior.

10. Bite for no reason.

1 1. Run like crazy.

12. Stiff posture when running or marching.

13. uneasy

14. Random biting during isolation (Figure 2).

15. sleepy

16. Unstable gait.

17. The posture of "dog sitting" is often presented (Figure 3). ...

How do you know when the puppy has rabies? What are the characteristics!

1. What is rabies? Rabies, also known as rabies, is an acute infectious disease caused by rabies virus, which mainly invades the central nervous system. Second, what is the drug resistance of rabies virus? Generally speaking, the resistance of mad virus is not strong, and sunlight, ultraviolet rays and ultrasonic waves can destroy it. Strong alkali, strong acid, potassium permanganate and iodine can all make it die, and it will die quickly in 1% formalin or 70% alcohol. After drying, it gradually loses its appeal. Sensitive to temperature, the virus can be completely killed at 56℃ for one hour, at 60℃ 10- 15 minutes, and at 100℃ for only 2 minutes. But low temperature is a good living condition for viruses. The virus in brain block can be preserved for several months at 4℃, and its infectious characteristics can still be maintained for several years at -70℃. . 3. How many kinds of rabies virus are there? There are two kinds of rabies virus: 1. Rabies virus isolated from patients and sick animals has the characteristics of neurotropic and salivary glands, which can make people or animals suffer from rabies. Its symptoms are mainly madness, which is called manic rabies. 2. Rabies virus isolated from bats in Central and South America can cause rabies after infecting people and animals. But its symptoms are mainly paralysis. It is called paralytic rabies. This virus is characterized by both neuroticism and visceral, and its invasion is relatively weak. But it can be spread by air, and the formation of endosomes in the brain is atypical. 4. What are the sources of rabies infection? Rabies infection comes from two sources. 1. Animals suffering from rabies and people suffering from rabies All warm-blooded animals can be infected with rabies, but the sensitivity is different, and mammals are the most sensitive. In nature, rabies has been found in domestic dogs, wild dogs, cats, wolves, foxes, jackals, badgers, pigs, cows, sheep, horses, camels, bears, deer, elephants, rabbits, squirrels, weasels and other animals. Birds are not sensitive. Rabies can also occur in chickens, ducks, geese and peacocks. However, the disease develops slowly and is usually paralyzed. Ducks are very resistant to rabies virus, only 29% can have neurological symptoms, and many can survive. All cold-blooded animals such as fish, frogs and turtles can resist rabies virus infection. In people with rabies, the virus can be isolated from their saliva. Although there are few cases of human-to-human transmission, it should be noted that infection through corneal transplantation can also occur. 2. "Healthy" dogs and animals with rabies virus Some animals are bitten by mad dogs, but they have no symptoms and will not die. It's just that there is a lot of rabies virus in saliva, and people who bite people will get seriously ill and die. And this "healthy" animal is still alive. This kind of recessive virus-carrying animals accounts for 15.2%, the virus-carrying rate of domestic animals is not high, and puppies are the most dangerous source of infection among dogs. Because these are often overlooked, they are worse than typical mad dogs. The greatest harm should be highly valued. 5. Why are dogs the main source of rabies? Because there is a habit of keeping dogs all over the world, dogs have the closest contact with people among animals. In addition, dogs are mobile and have the characteristics of biting behavior, so dogs have become the main link of rabies epidemic. According to statistics, the proportion of people bitten by various animals suffering from rabies is: 80.07% by dogs, 9.25% by cats, 0.64% by wolves, 0.03% by foxes and 0.64% by farm animals. Dogs account for the highest proportion, so dogs are the main source of infection. What are the modes of transmission of rabies? Rabies can be transmitted in the following three ways: 1. Bite or scratch by dogs or other animals, or lick mucous membrane infection. Rabies virus invades nerves through wounds and mucous membranes. This is the main mode of infection. 2. Inadvertently stabbing hand infection during slaughter or peeling. According to statistics, among 86 cases of rabies, 78 people were bitten and 8 people were infected by slaughtering dogs. 3. Infection through the digestive tract. Animals that died of rabies were buried underground, frozen in winter, pulled out by wild dogs or other animals, ate meat and became infected with rabies. Seven, suffering from rabies dogs or pigs and other livestock meat, processed into mature meat. Will it be infected if you eat it? The meat of an animal suffering from rabies will not get rabies even if it is cooked, because the rabies virus has died after boiling at 100℃ and is not contagious. However, animals suffering from rabies are prohibited from slaughtering, skinning and eating meat. In order to prevent peeling or knife cutting from stabbing hands or infecting chapped hands, please connect. ......

This puppy has symptoms of rabies.

The sick dog showed strong uneasiness and confusion. At the initial stage of the disease, the main manifestations are depression and abnormal behavior. Do not listen to the call, like to hide in the dark, addicted to gravel, wood blocks, mud and other things. Sick dogs often lick their bites with their tongues. Soon, he became furious, attacked people and animals, and often ran aimlessly. The sick dog gradually became emaciated in appearance, with drooping jaws and tail, and was sandwiched between hind legs. Hoarseness, increased salivation and dysphagia. In the later stage, the sick dog developed paralysis symptoms, had difficulty walking, and finally died of general failure and respiratory paralysis. If you have the above symptoms, it is recommended not to touch the dog to avoid accidentally injuring yourself.
