All of the following body fluids carry blood-borne pathogens EXCEPT:

Tears are considered to be a lower-risk bodily fluid when it comes to the transmission of blood-borne pathogens. Unlike the other fluids mentioned, tears generally do not contain the high concentrations of pathogens that are typically associated with blood, semen, vaginal secretions, or visibly blood-stained fluids like vomit. While it's important to acknowledge that tears can potentially carry some pathogens, they are not classified among the primary body fluids that are known to transmit blood-borne diseases such as HIV, Hepatitis B, or Hepatitis C.

The other fluids listed—such as bodily fluids from infected individuals, vomit containing visible blood, and semen and vaginal secretions—are all recognized for having higher risks associated with the transmission of blood-borne pathogens, making them significant concerns in health and safety protocols, especially in professional environments like schools and healthcare settings.
