I was scratched by my dog's paw and lost some blood. Do I need an injection? urgent

The problem you are worried about will get rabies! It's impossible. If you carefully look at the pathogenesis of rabies, you will understand that you should correctly understand rabies. Don't be misled and panic blindly. Actually, you don't have to worry. If there is medicinal liquor at home to wipe the wound and disinfect it, nothing will happen. If you don't have medicinal liquor, you can also use wine. The authoritative statement of the World Health Organization, referred to as the Rabies Research Center, is this. 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. (No injections) 2. The pathogenesis of rabies virus is that the virus invades animal brain cells and causes rabies attacks. At this time, animals generally 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. 3. Dogs (cats) only use poison after rabies attacks. Only if a warm-blooded animal that has had rabies bites, it is possible to spread rabies virus to people through saliva. At this time, you need to take rabies prevention. 4. In view of the fact that 100% of warm-blooded animals such as dogs and cats die within 3 ~ 5 days after the onset of rabies (it is rare to die within 8 days according to the literature). Therefore, it is infectious only 3-5 days before its death, and it is very dangerous to be bitten. Even if bitten, if the dog (cat) doesn't get rabies and dies within 10 days, you don't have to worry, because it was not in the infectious period when it bit you. (10 day is a safety observation period specially extended by the World Health Organization) (This period was originally proposed by Thai doctors. Note that Thailand is also a high incidence area and epidemic area of rabies) 5. If you are bitten by a warm-blooded animal such as a dog (cat) with disease symptoms, or behave abnormally with a healthy cat (dog), you should inject rabies vaccine as soon as possible after being bitten, and observe the cat (dog) that bit you. 6. Rabies has an incubation period. According to the detailed study of the World Health Organization, most of them are from 20 days to February, and the longest 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 six years, you can rest assured. If it is an old injury within six years, you can get another rabies vaccine, which is equivalent to an exposure (the first bite). PS: At present, China has formed a huge industrial chain with huge profits from rabies vaccination. It is not ruled out that organizations at all levels, drug dealers, the media and some irresponsible medical circles intentionally create panic and obtain improper benefits, especially the medical circles have great responsibilities!
