It is generally considered that, once symptoms develop, rabies virus infection in humans is invariably fatal. Nonetheless, there are rare published accounts of partial and near-full recovery of children and adults: the most recent being "Madhusudana, S.N. et al. 2002. Partial recovery from rabies in a six-year-old girl. Int J Infect Dis. 6(1):85-6."
I will try to find a better article. This one sites the International Journal of Infectious Disease.
