Mechanism of Infection Transmission Respiratory

[[“""The mechanism of transmission of infectious agents by the respiratory route is the mechanism of transmission of respiratory tract infections, in which the infectious agent is transmitted primarily by airborne droplets. Respiratory infections are usually characterized by the presence of infectious particles (aerosols) transmitted through inhalation of contaminated air”” - Wikipedia]].

Mechanism characteristics

With the airborne droplet mechanism, infections are transmitted from a sick person or carrier to a healthy person through direct contact with an infected person (during conversation, sneezing, coughing, etc.). This mechanism is observed among respiratory diseases such as influenza, acute respiratory infections, and acute respiratory viral infections. Also, respiratory infections can pass from mother to fetus during pregnancy. The source of infection in this situation will be the sick mother. A sick source of infection transmits pathogens into the air by releasing various bacteria, viruses, and toxins. Such substances settle in the environment and also transfer to other objects and surfaces. When an infected person or object touches the mucous membrane of a healthy person, the latter becomes infected. Depending on which pathogenic microorganism caused the disease, the route of transmission of infection may differ. But the main routes of transmission of respiratory tract infections are: * airborne dust; * aspiration; * drip.
