👉 The term "transmission infection" refers to the process by which a pathogen, such as a virus or bacterium, spreads from one host to another. This can occur through various routes including direct contact, airborne droplets, vectors like mosquitoes, contaminated food or water, or through bodily fluids. Transmission can be categorized into several modes: sexual, respiratory, fecal-oral, vector-borne, and contact. Understanding transmission is crucial for developing strategies to prevent the spread of infectious diseases, such as implementing hygiene practices, vaccination programs, and public health interventions. For example, the COVID-19 pandemic highlighted the importance of controlling transmission through measures like mask-wearing, social distancing, and quarantine to reduce the spread of the virus.
