严老师这一段外国专家的话,我们应该怎么去理解,恳请您解惑:
Rabies virus can indeed stay dormant after exposure to the virus for a long time, however, the tissues (e.g. muscle or neurons) where the virus infection can persists is not known. Since your friend responded satisfactory to the PEP, an activation of a potentially silent infection where ever it may be located is very remote. Nevertheless, I recommend that your friends VNA titer is checked every 6 month for the next two years and he should receive a booster immunization if the VNA titer had decreased below the protective level (< o.5 IU).
