Means of transmission involves?
Direct contact
Indirect contact
Droplet

What is the common route in humans for portal of exit?
breaks in cutaneous membrane, respiratory, gi, and gu tracts
an inanimate object which acts as a means of transmission is?
formite
a living creature that transmits infectious agent to humans
vector
point at which organisms enter a new host
Portal of entry
What are the different stages of infection?
incubation, podromal, full/acute, convalescent
interval between invasion and appearance of symptoms
incubation period
when a person is most infectious, though person is often unaware they are contagious. early signs and symptoms of disease are present but these are often vague and nonspecific
prodromal stage
when infection specific signs and symptoms shows
full/acute stage of illness
