Arkansas State Barber Practice Exam

People with HIV have high levels of the virus in their blood, which can enter the bloodstream of another person if their blood mixes with that person's blood. This can happen if an infected barber accidentally cuts themselves while using a tool and then uses the same tool on another person without properly disinfecting it. HIV cannot be spread through water or airborne particles, and sharing tools does not necessarily mean blood-to-blood contact. Therefore, B is the most likely manner in which HIV may be transmitted in a barbershop.
