But some animals may carry rabies virus, but it is recessive and will not break out. In this case, the bitten person may have an incubation period, for example, the incubation period may be as long as ten years, so although there is no disease on the spot, there is still the possibility of an outbreak afterwards. Once rabies breaks out, there is no cure, so I suggest you go to the hospital for an injection as soon as possible after being bitten by a small animal.
Some people have been vaccinated against rabies before, and their bodies have produced antibodies. In this case, if you are bitten by a small animal, you just need to clean the wound! It is safe to make sure that your wound is not infected. So from this point of view, rabies vaccine is still very useful, so if you are bitten by a small animal, you must go to the local hospital and inject rabies vaccine according to the process. If it has been injected before and it is within the validity period, it is not necessary to inject it.
To sum up, this man was bitten by a small animal and didn't take a vaccination. There are three situations, the first is small animals and health, the second is that it has not broken out, and the third is that it has been vaccinated and has antibodies. All three are possible.
