Which of the following best describes a portal of exit?. • The method by which an infectious agent is destroyed by the immune system. • The process by which an infectious agent is transmitted from one host to another. • The route through which an infectious agent enters a new host. • The route through which an infectious agent leaves its host.

Which of the following best describes a portal of entry?. • The process by which an infectious agent is transmitted from one host to another. • The method by which an infectious agent is destroyed by the immune system. • The route through which an infectious agent leaves its host. • The route through which an infectious agent enters a new host.

Which of the following best describes direct contact transmission?. Transmission that typically occurs through physical contact between an infected person or the infectious agent and a susceptible person. Transmission that occurs when an infectious agent is transmitted through an intermediate object or surface. Transmission that involves an infectious agent being ingested through contaminated food or water. Transmission that typically occurs when an infectious agent is carried through the air and inhaled by a susceptible person.

Transmission that occurs through large respiratory droplets when an infected person coughs, sneezes, talks, or exhales is generally known as?. • vehicle-borne Transmission. • Airborne Transmission. • Vector-borne Transmission. • Droplet Transmission.

Droplet transmission is typically viewed as a form of direct contact transmission. (True or False). True. False.

Which of the following best describes indirect contact transmission?. Transmission that typically occurs through direct physical contact between an infected person and a susceptible person. Transmission that typically occurs when there is no direct human-to-human contact, often involving transfer through contaminated surfaces, instruments, or food/water. Transmission that typically occurs when there is physical contact between an infected person or the infectious agent itself and a susceptible person, such as through skin-to-skin contact, sexual intercourse, or respiratory droplets. Transmission that involves large respiratory droplets landing on a nearby person's mucous membranes.

Indirect contact transmission typically occurs when there is physical contact between an infected person and a host. (True or False). False. True.

Indirect contact transmission typically occurs when there is no human-to-human contact between an infected person and a host. (True or False). True. False.

Indirect contact commonly occurs through which of the following? (Select all that apply). Hand washing. Vehicles. Aerosols. Asepsis. Large respiratory droplets. Vectors.

Transmission caused by tiny respiratory droplets or aerosols that can stay suspended in the air for longer periods is generally known as: Droplet transmission. Vehicle-borne transmission. Airborne transmission. Vector-borne transmission.

Transmission caused by tangible items such as food, water, drugs, or fomites is generally known as: Airborne transmission. Vehicle-borne transmission. Vector-borne transmission. Droplet transmission.

Contaminated inanimate objects are commonly referred to as: • Insects and animals. • Aerosols. • Fomites. Hosts.

Which of the following could be a potential fomite?. • All answers are correct. Clothing. Bedding. • Imaging coils.

Transmission that occurs through living intermediaries such as insects and animals is generally known as: • Airborne transmission. • Vector-borne transmission. Vehicle-borne transmission. • Droplet transmission.

Which type of vector-borne transmission typically occurs when pathogens are physically transported by a vector from a contaminated source to a susceptible host without undergoing changes or multiplying within the vector?. • Mechanical Vector-borne Transmission. Biological Vector-borne Transmission. • Airborne Transmission. • Droplet Transmission.

What term generally describes the state of being free from disease causing pathogens or microorganisms?. Asepsis. Personal protective equipment (PPE). latrogenic. Standard Precautions.
