humanpatogener
Human pathogens, or humanpatogener, are biological agents that can cause disease in humans. They span multiple biological kingdoms and include bacteria, viruses, fungi, parasites, and prions. Not all organisms that contact humans are pathogenic; many are harmless or beneficial. Pathogens may require a host to replicate and can cause a range from mild to life-threatening illnesses.
Transmission routes vary: direct contact (hands, wounds), droplets and aerosols, vectors such as mosquitoes, fomites, contaminated
Pathogens are classified taxonomically into bacteria, viruses, fungi, and parasites, with prions as protein-based infectious agents.
Public health aims to prevent and control infections through vaccination, antimicrobial stewardship, hygiene and sanitation, safe
Global travel, climate change, and urbanization influence the distribution and emergence of human pathogens. Understanding pathogen
