Final answer:
Bloodborne pathogens are transmitted when infected blood or bodily fluids enter someone's bloodstream, commonly through IV drug use, sexual transmission, or healthcare-related exposure, but also through contaminated medical equipment or vertical transmission.
Step-by-step explanation:
Bloodborne Pathogens Transmission
Bloodborne pathogens are transmitted from one person to another when infected blood or bodily fluids gain entry into someone's bloodstream. This transmission can occur through various means, including intravenous (IV) drug use, sexual transmission, or exposure to blood via healthcare practices.
These pathogens can also be passed through other methods such as contaminated catheters, dental procedures, or through piercings and wounds. Moreover, they can be spread from an infected mother to her child during pregnancy, birth, or breastfeeding, known as vertical transmission. Understanding the different ways that these pathogens can enter the bloodstream is essential for preventing the spread of diseases they may cause.
