The incubation period for rabies is usually 1-3 months, most commonly 60 days, and the vast majority of people are within this time frame. However, the incubation period for rabies may also be shortened or lengthened, with the shortening as well as the lengthening occurring at relatively large intervals. If it is shortened, it may be shortened to about a week, with the shortest time seen in the relevant sources being 4 days and some describing 5 days. The shortening of the incubation period of rabies is mainly due to the deeper wounds or the more obvious distribution of nerve endings at the wound site, which may lead to the shortening of the incubation period. If the incubation period is prolonged, it usually does not exceed 1 year, and although cases of more than 1 year can be seen, they are not too numerous in the overall rabies cases, and the relevant percentage is usually around 7%. The incubation period is prolonged and may extend to several years or even to a decade or more, but this is not generally the case. Therefore, it is generally considered that rabies bites longer than 1 year, there is no need to worry too much about the onset of rabies.
