A bloodborne pathogen, which is a disease-causing microorganism, can be spread from one person to another in the following ways:
1. Through the infected person's blood: Direct contact with infected blood, such as sharing needles, can transmit bloodborne pathogens like HIV or hepatitis B and C.
2. Through "other potentially infectious materials" from the infected person: This includes body fluids like semen, vaginal secretions, and cerebrospinal fluid, which can also contain bloodborne pathogens. Proper precautions are necessary when dealing with these materials to prevent transmission.
It is essential to note that bloodborne pathogens are not typically spread through casual contact or when an infected person sneezes. These pathogens require specific modes of transmission involving direct exposure to infected bodily fluids to cause transmission. Understanding these modes of transmission is crucial in preventing the spread of bloodborne diseases.
