Her miraculous survival has not only challenged a time-honored scientific fact, but has also brought about a new method of Rabies treatment, known as the Milwaukee Protocol.
Can rabies occur after 10 years?
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.
