Risk for rabies transmission from encounters with bats, Colorado, 1977-1996.Emerg Infect Dis. 1999 May-Jun; 5(3):433-7.EI
To assess the risk for rabies transmission to humans by bats, we analyzed the prevalence of rabies in bats that encountered humans from 1977 to 1996 and characterized the bat-human encounters. Rabies was diagnosed in 685 (15%) of 4,470 bats tested. The prevalence of rabies in bats that bit humans was 2.1 times higher than in bats that did not bite humans. At least a third of the encounters were preventable.
