Hepatitis B, hepatitis C and AIDS
three infectious materials that can contain bloodborne pathogens
Direct contact, contamination and exchange of fluids.
The three potentially infectious materials (PIM) are blood, certain body fluids, and any materials that may contain blood or bodily fluids. This includes items like saliva, urine, and vomit if they are visibly contaminated with blood. Additionally, tissues and organs from infected individuals can also be considered potentially infectious. Proper handling and disposal of these materials are crucial to prevent the spread of infections.
Food, or contact with mucus membranes can spread either of those.
Yes, all three are bloodborne pathogens. See link below for more details.
The three major ways is through water, food, and/or air
Blood, lymph, and cerebrospinal fluid are three fluids that run through the human body. Blood carries oxygen and nutrients to cells, while lymph helps remove waste and toxins from tissues. Cerebrospinal fluid surrounds the brain and spinal cord, providing cushioning and support.
Communicable diseases spread from one person to another by pathogens. Three well-known communicable diseases are the common cold, strep throat, and HIV/AIDS.
PhagocytosisPhagocytes make up three-quarters of the body's white blood cells. They destroy pathogens by engulfing them.It's called phagocytosis. Macrophages mainly phagocytose the pathogens.
Infectious disease in one that is spread by intimate contact with body fluids. Some of these are influenza, mononucleosis, and Chlamydia.
Body fluids are things like sweat, tears, blood, urine, CSF, mucus, genital secretions, breast milk; just about anything that is a part of or can come out of the body.
HIV, the retrovirus that causes AIDS, is present in the semen, vaginal secretions, blood, breast milk, and in the amniotic fluid of an infected person. Contact with these fluids can cause a person to become infected with HIV. However, the saliva of an infected person is generally considered safe (unless contaminated with blood/the non-infected person has open wounds in their mouth).
