Introduction of Direct and Indirect Transmission of HIV
There are two ways that HIV can be spread: direct and indirect.
Direct transmission of HIV occurs when the virus enters the body through a break in the skin or through contact with infected blood, semen, or vaginal fluid. This can happen during sex, when sharing needles or other drug paraphernalia, or when coming into contact with an open wound or mucous membrane (like the inside of your mouth) of an HIV-positive person.
Indirect transmission of HIV can occur when the virus is passed from an HIV-positive person to another person through contact with infected blood, semen, or vaginal fluid. This can happen through sharing needles or other drug paraphernalia, or when coming into contact with an open wound or mucous membrane of an HIV-positive person. Indirect transmission can also occur when an HIV-positive person transmits the virus to another person through breastfeeding or contact with infected blood in the birth canal.
Direct Transmission
Direct transmission is a term used in epidemiology to describe the spread of a pathogen from one person to another without an intermediate host. This can be through contact with an infected person, such as through coughing and sneezing, or contact with infected body fluids. Direct transmission can also occur through contact with objects or surfaces that have been contaminated with the pathogen.
Indirect Transmission
Indirect transmission of a pathogen occurs when an infected individual transmits the pathogen to another individual without being aware that they are infected. This can occur through contact with contaminated surfaces, objects, or people. Indirect transmission is often responsible for the spread of infections in healthcare settings, as pathogens can be easily transferred from one individual to another.
