The incubation period of rabies in humans is generally 20–60 days. However, fulminant disease can become symptomatic within 5–6 days; more worrisome, in 1%–3% of cases the incubation period is >6 months. Confirmed rabies has occurred as long as 7 years after exposure, but the reasons for this long latency are unknown.

Can blood test detect rabies?
To date, there are no tests available to diagnose human rabies infection ante-mortem, or before the onset of clinical disease.
Can you get rabies if not bitten?
