Factors Affecting Disease Potential

Virulence, infectivity, and pathogenicity are factors that affect an organism's potential to produce disease.
Host factors, such as age, immune status, and underlying health conditions, also impact an organism's potential to produce disease.

Stages of Infection

The stages of infection are: exposure, infection, colonization, disease, and transmission.

Modes of Transmission

Modes of transmission for pathogens include: direct contact, indirect contact, airborne, and vector-borne transmission.
Vertical transmission, from mother to child, is also a mode of transmission.

Reservoirs for Pathogens

Reservoirs for pathogens include: humans, animals, environment, and fomites.

Portals of Entry for Pathogens

Portals of entry for pathogens include: skin, mucous membranes, respiratory tract, gastrointestinal tract, and genitourinary tract.

Healthcare Acquired Infections (HAI)

Healthcare acquired infections (HAI) are infections that patients acquire during the course of receiving healthcare.
Examples of HAI include: surgical site infections, urinary tract infections, and pneumonia.

Prevention of Healthcare Acquired Infections (HAI)

Hand hygiene is the #1 prevention for healthcare acquired infections (HAI).

Chain of Infection

The chain of infection consists of: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.

Types of Pathogens

Prions are the smallest pathogens, consisting of abnormally folded proteins.
Other types of pathogens include: bacteria, viruses, fungi, and parasites.

Test your knowledge of infectious diseases with this quiz on factors affecting disease potential, stages of infection, modes of transmission, reservoirs for pathogens, portals of entry, and healthcare acquired infections (HAIs). Find out which factors, stages, modes, reservoirs, and portals are not associated with disease transmission.
