Q

Define Portal of exit

A

A portal of exit is where the pathogen can potentially leave the reservoir.

i.e. the reservoir is a person, the exits out of a human body includes any of the openings (such as mouth, nose, vagina, urethra, rectum) and artificial ones such as ostomies, any breaks in the skin from a wound.

Q

Define Vector

A

A vector (doesn’t develop the disease) is any agent which carries and transmits an infectious pathogen into another living organism.

i.e., might mostly be organisms such as intermediate parasites, microbes, arthropods or other insects (through bites).

16
Q

Describe Direct Contact Transmission

A

Physical skin to skin contact between an infected individual and a susceptible host.

17
Q

Describe Indirect Contact Transmission

A

Where a susceptible host comes into contact with a contaminated intermediate object.
