狂犬病毒的潜伏期
最佳答案：
Incubation period
The incubation period for rabies is the most variable of all acute CNS infections. The average incubation period is around 1-3 months but may range from less than 7 days to 6 years. It is not still clear why there is such a variable and prolonged incubation period. The incubation period may depend on several factors including density of rabies virus receptors in the affected tissue,the degree of innervation in tissues,the quantity of virus inoculated and the properties of the rabies virus stain. It is assumed that cases with unusually prolonged incubation period may be due to a trivial exposure considered insignificant and therefore not disclosed. It is also possible that there may be no history of bite in some cases of human rabies. In our experience at NIMHANS from 1993 to 2004,2 cases out of 37 autopsy confirmed rabies cases gave no history of animal bite. In Thailand,nearly 6% of 707 cases of human rabies in the past two decades had no history of bite.","department":"
