👉 Purchasing-infection is a process where pathogens, such as bacteria, viruses, or parasites, enter the body through various routes (e.g., ingestion, inhalation, or direct contact) and establish an infection by exploiting host vulnerabilities. Once inside, these microorganisms can multiply and cause disease by disrupting normal cellular functions, evading the immune system, or producing toxins. The infection can range from mild to severe, depending on the pathogen's virulence and the host's immune response. Understanding this process is crucial for developing effective prevention and treatment strategies, such as vaccines, antibiotics, and hygiene practices.
