👉 Transmitted infection occurs when a pathogen, such as a virus or bacterium, moves from an infected individual to a susceptible host through various means like direct contact, airborne droplets, contaminated surfaces, or vectors like mosquitoes. This process involves the pathogen surviving and replicating within the new host's body, often exploiting the host's cellular machinery to spread further. Transmission can be direct, where physical contact facilitates the transfer, or indirect, involving intermediaries such as contaminated objects or vectors. Once inside the host, the pathogen can cause disease by disrupting normal bodily functions, leading to symptoms and potentially severe health outcomes. Preventive measures include hygiene practices, vaccination, and isolation to break the chain of transmission.
