Study Notes
Transmission Pathways of Pathogenic Microorganisms
- Infectious agents can be transmitted directly from infected humans or animals
- Infectious agents can transmitted indirectly through vectors, airborne particles or vehicles
- Vectors are insects or other animals that carry the infectious agent
- Vehicles are contaminated objects or elements of the environment (such as clothes, cutlery, water, milk, food, blood, plasma, parenteral solutions or surgical instruments)
- Carriers are people who can transmit an infection without showing symptoms
- Secondary sources of infection are inanimate objects, materials, or third persons contributing to transmission of pathogens from the primary source to predisposed persons
