Tartuntatiet refers to the ways in which infectious diseases are transmitted from one person, animal, or environmental source to another. Understanding these transmission routes is crucial for preventing the spread of illness and implementing effective control measures. The primary modes of transmission can be broadly categorized.

Direct contact transmission occurs when pathogens are transferred through physical touch, such as kissing, sexual contact, or touching an infected person or contaminated surfaces. Droplet transmission involves the dispersal of larger respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets travel short distances and can infect individuals who are nearby. Airborne transmission, on the other hand, involves the spread of smaller respiratory particles that can remain suspended in the air for longer periods and travel further distances, allowing for transmission to people in different rooms or even buildings.

Vehicle transmission occurs when a pathogen is transmitted through a common contaminated source. This can include contaminated food, water, blood, or medical equipment. Vector-borne transmission involves the spread of disease through an intermediate living organism, typically an insect like a mosquito or tick, which picks up the pathogen from an infected host and transmits it to a new host. Finally, fomite transmission is a type of indirect contact where a susceptible person touches a contaminated inanimate object (fomite) and then touches their own mucous membranes, such as their eyes, nose, or mouth, allowing the pathogen to enter their body.
