👉 Freelance infection, also known as freelance transmission or person-to-person transmission, occurs when an infected individual spreads a pathogen directly to another person without the involvement of vectors like mosquitoes or other intermediate hosts. This type of transmission is common in diseases such as influenza, tuberculosis, and sexually transmitted infections. It relies on close contact, respiratory droplets, or direct physical contact between individuals, making it highly dependent on human behavior and environmental factors. Unlike vector-borne infections, freelance infection does not require an intermediary organism to carry the pathogen from one host to another, emphasizing the direct nature of human-to-human spread.
