Probably not: The incubation period in humans averages 4 to 6 weeks. Incubation periods of up to 6 years have been confirmed.

The average incubation period is one to three months, but can range from several days to one year after exposure. There are rare case reports of longer incubation periods that may be related to inadequate rabies prophylaxis or an unknown new exposure.
