👉 The term "sale-infection" refers to the process by which an organism, typically a pathogen like a virus or bacterium, is transmitted from one host to another, often through direct contact, bodily fluids, or vectors such as insects. This transmission can lead to infection, where the pathogen invades and begins to replicate within the new host's body, potentially causing disease. For example, when an infected person coughs or sneezes, droplets containing the pathogen can infect others who inhale them. Similarly, direct contact with contaminated surfaces or bodily fluids can also result in infection. Understanding this process is crucial for implementing effective prevention and control measures to reduce the spread of infectious diseases.
