👉 Infection refers to the process by which a pathogen, such as a virus or bacterium, enters and takes control of a host cell, leading to the replication and spread of the pathogen within the body. This can result in various symptoms and diseases, depending on the type of pathogen and the affected area. For instance, when a virus infects a cell, it hijacks the cell's machinery to produce more viral particles, potentially causing cell damage or death. Infections can be transmitted through various means, including direct contact, airborne droplets, contaminated surfaces, or vectors like mosquitoes. Understanding infection is crucial for developing preventive measures, treatments, and vaccines to protect public health.
