Transmission routes refer to the pathways through which diseases or infections spread from one host to another. These routes can include direct contact, such as touching an infected person, or indirect contact, like touching surfaces contaminated with pathogens. Other common transmission methods include airborne particles, droplets from sneezing or coughing, and vector-borne transmission through insects like mosquitoes. Understanding transmission routes is crucial for controlling outbreaks and preventing illness. Public health measures, such as vaccination, hand hygiene, and wearing masks, aim to interrupt these routes. By identifying how diseases spread, health officials can implement strategies to protect communities and reduce the risk of infection.
