Why is the risk of HIV infection low for a person whose coworker has tested positive HIV?

There is no or negligible risk of transmission of the Human Immunodeficiency Virus (HIV) just by being in the presence of a co-worker who has tested positive for the virus. HIV is not spread through casual contact such as sharing of office equipment, work surfaces, or incidental bodily contact that does not involve the exchange of bodily fluids.

Transmission of HIV primarily occurs through unprotected sexual contact, sharing of needles or injection drug equipment, or from an infected mother to her child during pregnancy, childbirth, or breastfeeding.

It's important to remember that HIV is not spread through casual interactions, and it is safe to work with someone who is HIV-positive.
