👉 Infection involves the process by which a pathogen, such as a virus or bacterium, enters and takes over a host cell, leading to cellular damage and potentially causing disease. This infection can occur through various routes, including respiratory droplets, contaminated food or water, or direct contact. Once inside the host, the pathogen replicates, often triggering an immune response that may cause inflammation and symptoms. However, in some cases, the infection can be asymptomatic, with the pathogen remaining dormant until conditions favor its activation or spread. Understanding the mechanisms of infection is crucial for developing preventive measures and treatments to combat infectious diseases.
