Infectious Diseases: Prevention, Transmission, and Public Health
Strategies
What are the three focus areas in Healthy People 2030 objectives related to infectious
diseases? - correct answer Occurrence and transmission of infection, control of infectious
diseases, and types of immunity.
Who has statutory responsibility for preventing the introduction, transmission, and spread of
communicable diseases in the U.S.? - correct answer The Secretary of the Department of Health
and Human Services.
What is virulence in the context of infectious diseases? - correct answer The degree to which an
organism can cause disease or its degree of communicability.
What are the leading causes of communicable disease deaths? - correct answer Acute
respiratory infections, HIV/AIDS, diarrheal diseases, tuberculosis, malaria, and measles.
Who are populations at risk for communicable diseases? - correct answer Young children, older
adults, immunosuppressed clients, high-risk lifestyle clients, international travelers, and
healthcare workers.
What are the six links in the chain of transmission of infectious diseases? - correct answer
Infectious agents, reservoirs, portals of exit, modes of transmission, port of entry, and host
susceptibility.
What are the two main modes of transmission for infectious diseases? - correct answer Vertical
transmission (from parent to offspring) and horizontal transmission (person-to-person
interactions).
What is an example of vertical transmission? - correct answer Transmission through sperm,
placenta, vaginal contact during birth, or human milk.
What is an example of horizontal transmission? - correct answer Contact with a person,
objects, air, contaminated body fluids, food, water, or vectors like mosquitoes.
What are vectors in the context of infectious diseases? - correct answer Animals that can
transmit infectious agents through biological and mechanical routes.
What are fomites? - correct answer Inanimate objects, materials, or substances that act as
transport agents for microbes.
What are the types of foodborne infections? - correct answer Bacterial, viral, and parasitic
infections of food, such as norovirus and salmonellosis.
, What is the difference between food infection and food intoxication? - correct answer Food
infection is caused by pathogens in food, while food intoxication is due to toxins produced by
bacteria.
What are some examples of waterborne diseases? - correct answer Cholera, typhoid fever,
bacillary dysentery, and Giardia lamblia.
What is herd immunity? - correct answer Protection due to the immunity of most community
members, making exposure unlikely.
What are the two types of acquired immunity? - correct answer Active immunity (production of
antibodies in response to infection or immunization) and passive immunity (transfer of
antibodies).
What role do nurses play in the prevention and control of communicable diseases? - correct
answer Nurses create community programs, monitor treatment adherence, and use public
health core functions to target diseases.
What is the significance of monitoring individuals' adherence to treatment regimens? - correct
answer It helps minimize the spread of disease and reduces the risk of complications.
What are some examples of sexually transmitted infections? - correct answer HIV/AIDS,
chlamydia, gonorrhea, syphilis, HPV, and genital herpes.
What are the airborne diseases that require isolation precautions? - correct answer Measles,
chickenpox, tuberculosis, and severe acute respiratory syndrome (SARS).
What is the role of public health nurses in policy development? - correct answer They can
develop programs for community health interventions, such as insecticide spraying.
What is communicable disease surveillance? - correct answer The systematic collection and
analysis of data regarding infectious diseases.
What type of epidemiology is used to investigate disease patterns? - correct answer Descriptive
epidemiology.
What can information from disease surveillance help identify? - correct answer Unusual disease
outbreaks or newly emerging diseases.
What is one purpose of data collected from communicable disease surveillance? - correct
answer To develop public health policies regarding disease management.
How can community health nurses track the origin of diseases? - correct answer By identifying
common individuals, communities, or contaminated sources.
What is mandated by state and local regulations regarding communicable diseases? - correct
answer Reporting of communicable diseases.
