A splash to the mucous membranes of the eyes, nose, or mouth

Body fluids capable of transmitting:
AIDS virus (HIV)
Hepatitis B virus (HBV)
Hepatitis C virus (HCV)
Blood, serum, plasma and all body fluids visibly contaminated with blood
Laboratory specimens, samples, or cultures that contain concentrated HIV, HBV, or HCV
Organ and tissue transplants (if not screened)
Pleural, amniotic, pericardial, peritoneal, synovial, and cerebrospinal fluids
Uterine or vaginal secretions, or semen (unlikely to transmit HCV)
Saliva (for HCV, HBV, and HIV if a bite is contaminated with blood, and for HBV if a bite is not contaminated with blood)
Feces, nasal secretions, sputum, tears, urine, and vomitus are not implicated in the transmission of HIV, HBV, and HCV unless visibly contaminated with blood
Risk
The risk of acquiring HBV from accidental exposure to a positive HBV patient is six to 30 percent
The risk of acquiring HCV from accidental exposure to a positive HCV patient is four to 10 percent
The risk of acquiring HIV from accidental exposure to a positive HIV patient is 0.36 percent
