fungiReservoir - environment ofr the agent; humans, animals, plants, insects, water, and soil Portal of Exit
- the way the agent leaves the reservoir; skin, respiratory tract, genital tract, conjunctiva, vertical
transmission (parent to offspring) Means of transmission - airborne, contact, droplet, indirect
(contaminated intermediate inanimate object) Portal of Entry - the way the agent enters the host; skin,
respiratory tract, genital tract, conjunctiva, vertical transmission (parent to offspring) Susceptible Host -
