Modes Of Transmission

Question 1

What are the types of infection?

Answer 1

Acute: severe and rapid onset
Chronic: present for a long duration
Latent: persistent, symptoms come and go(cold sores)
Opportunistic: Individuals whose resistance is decreased or compromised (auto immune disease, diabetics, elderly)

Question 2

Explain infectious diseases and the two ways they are transmitted

Answer 2

Is spread by or transmitted in some way from one host to another host Communicable: capable of being transmitted from person to person, animal to animal, or human to animal
Contagious: capable of being transmitted directly or indirectly as an infectious disease

Question 3

Explain four different types of infections

Answer 3

Acute: severe and rapid onset
Chronic: present for a long time
Latent: persistent, symptoms come and go (cold sores)
Opportunistic: individuals whose resistance is decreased or compromised

Question 4

Explain how the chain of transmission works

Answer 4

Infectious agent(Bacteria, fungi, viruses) ➡️ source(people, equipment, water)➡️ Exist (Aerosols splatter) ➡️ Means of transmission (direct contact, inhalation, airborne) ➡️ Portal of Entry(mucus membranes, respiratory tract, broken skin) ➡️ susceptible Host

Question 5

Explain ways to break the chain of transmission

Answer 5

Infectious agent (diagnosis/treatment) ➡️ source( education/policy, environmental sanitation, disinfection )➡️ Exist (handwashing, control of aerosol and splatter) ➡️ Means of transmission (isolation, disinfecting, handwashing ) ➡️ Portal of Entry(first aid, personal hygiene, handwashing ) ➡️ susceptible Host( treatment of underlying diseases, immunization)
