The following is the popular science of rabies vaccine.
Description of the World Health Organization on Rabies Vaccine
1. Healthy dogs (cats and other animals) are not poisonous. ("Highly toxic" is a medical term, which means "infectious". "Non-toxic" here means that even if cats and dogs carry rabies virus, they are not contagious before they get sick. )
It looks healthy, but dogs that actually carry rabies virus will not infect you until they get sick. So many examples are the reasons why some people were bitten by dogs and didn't get an injection, but they didn't get sick for more than ten years.
2. The mechanism of rabies virus is that the virus attacks animal brain cells and causes rabies attacks. At this time, animals will have very obvious abnormalities and are easy to identify. At this time, the saliva of animals is toxic (virus) and contagious. If you are bitten by such animals, you must get rabies vaccine.
Dogs (cats) will be infected only after the onset of rabies. Only when a warm-blooded animal with rabies symptoms bites, it is possible to spread rabies virus to people through saliva. At this time, you need to take rabies prevention.
4. Warm-blooded animals such as dogs and cats die within 3 to 4 days after the onset of rabies. Therefore, only 3-4 days before its death is the infectious period, and it is very dangerous to be bitten. Even if you are bitten, 10 days later, this cat and dog died of rabies, you don't have to worry, because when you were bitten, you were not in the infectious period. (10 day is the safety observation period specially extended by the World Health Organization)
5. After being bitten by a warm-blooded animal such as a dog (cat), obvious disease symptoms and abnormal behavior of a healthy cat (dog) appear, you should immediately inject rabies vaccine and observe the cat (dog) that bit you. If the cat or dog doesn't die of rabies within 10 days, you can stop the rabies vaccine and judge that you are not infected with rabies at all.
6. Rabies has an incubation period. According to the detailed study of the World Health Organization, most cases last from 20 days to February, and the longest period is 6 years. As for some cases in China, the World Health Organization expressed doubts. There is no evidence of long-term latent cases in the world, and infectious disease medical experts think it may be misdiagnosis or secondary exposure (medical terminology, secondary transmission).
7. Rabies vaccination can be delayed. (If you have been bitten for 6 years, you can rest assured. If you are not at ease, you can get another rabies vaccine, which is equivalent to an exposure (the first bite).
Experimental infection studies have proved that dogs and cats generally have no virus in saliva during incubation period, and the virus will not be excreted in saliva until 1-2 days before onset to 3 days after onset. This is the conclusion that American scientists made experiments with more than 100 animals nearly 50 years ago, which has been proved by practical experience and widely quoted in western books and periodicals as a classic document. During the quarantine observation period of 10 days for dogs, cats or ferrets (a pet of Americans), no one has ever been sick in the United States.
Please note that this refers to "observing suspicious dogs and cats in isolation after biting 10 days". If you are bitten by your own dog, there has been no rabies in your city for many years, and the dog is kept at home, never running around, never bitten by other suspicious dogs and vaccinated, then you don't need to be nervous.
But if you look at "WHO's Ten-Day Observation Method", you will find that some people are denouncing this method, saying that it is deceptive.
You can find that this report is consistent with what Professor Zu Shuxian said, and there is no mention of the need for vaccination before observation! Why can we use the "ten-day observation method"? Because rabies virus can only infect people within 5 days before the dog with the virus gets sick, that is, only dogs infected with rabies virus will bite you during this period and you will be exposed. In order to improve safety, WHO deliberately increased the time to 10 days. If a dog is still alive and kicking after 10 and has no rabies symptoms, then you are not exposed at all. What should you do? Gossip ends with the wise! I hope you have a rational judgment! (This is an excerpt from some authors. )
I read some articles on Baidu, which really scared me to death. There was a lot of news. I was scared when I got an injection, too. I immediately searched for rabies content on various platforms and calculated my mortality rate. I was driven crazy, and I almost didn't find a psychiatrist. It's really Wang Jiong. If you read this article and see here, it means that you are as upset as I am. Please don't worry, rabies virus is not easy to be infected.
