If a dog bites a person with rabies, the rabies virus can easily enter the body through the wound and cause a rabies attack. The most common incubation period for rabies is between 1 and 3 months after the injury. But it must also depend on the intensity of the rabies virus toxicity of the infection, or the personal constitution of the infected person is also more relevant. If the rabies virus is very virulent and the person bitten is weak, the time for rabies to strike is very short, the shortest possible being 3-7 days after the bite. However, if the rabies virus is very weak and the person’s constitution is very good, the incubation period may be very long, even more than 1 year, and the longest incubation period found in the world is 6 years.
