a microorganism that causes disease

• Pathogen

• Reservoir

• Fomites

• Vector

• Vehicle

a natural environment in which a pathogen typically lives

• Pathogen

• Reservoir

• Fomites

• Vector

• Vehicle

objects or materials that are likely to carry infection, such as clothes, utensils and furniture

• Pathogen

• Reservoir

• Fomites

• Vector

• Vehicle

occurs when a substance, such as soil, water, or air, carries an infectious agent to a new host.

• Pathogen

• Reservoir

• Fomites

• Vector

• Vehicle

occurs when a living organism carries an infectious agent on its body (mechanical) or as an infection host itself (biological), to a new host

• Pathogen

• Reservoir

• Fomites

• Vector

• Vehicle

pathogens are passed from one person to another without an intermediary

• direct transmission

• indirect transmission

animals serve as vectors carrying the pathogens, or inanimate objects serve as vehicles from one host to the next

• direct transmission

• indirect transmission

pathogens passed through fomites

• direct transmission

• indirect transmission

pathogens passed through vehicles

• direct transmission

• indirect transmission

pathogens passed through vectors

• direct transmission

• indirect transmission
