Which of the following are examples of living reservoirs of infection?
Soil and water
Food and fomites
Humans (carriers) and animals (zoonoses)
Air and surfaces
Which of the following are examples of non-living reservoirs of infection?
Humans and animals
Air and skin
Soil, water, food, and objects
Blood and saliva
Which type of transmission involves direct physical contact such as touching or sexual contact?
Indirect contact
Direct contact
Vehicle transmission
Droplet transmission
Transmission through nonliving objects (fomites) such as doorknobs or utensils is called:
Direct contact
Indirect contact
Droplet transmission
Airborne transmission
Coughing and sneezing are examples of which type of transmission?
Droplet transmission
Vehicle transmission
Vector transmission
Indirect contact
Which of the following best describes vehicle transmission of disease?
Spread of disease through fomites like doorknobs or towels
Spread of disease through fomites like doorknobs or towels
Transmission of pathogens through inanimate mediums such as water, food, air, blood, body fluids, drugs, or intravenous fluids
Which type of vector transmission involves insects carrying pathogens passively, such as a fly landing on feces and then on your food?
Biological transmission
Direct contact
Mechanical transmission
Vehicle transmission
Which type of vector transmission involves pathogens living inside the insect and actively being transferred (like a mosquito bite)?
Vehicle transmission
Biological transmission
Mechanical transmission
Airborne transmission
What is a nosocomial infection?
An infection you get from animals
An infection you get before entering the hospital
A hospital-acquired infection that develops during a stay in a healthcare facility
A genetic infection you are born with
What does the term principal sites refer to?
The main hospital departments
The most common areas in the body where infections occur
The types of antibiotics used to treat infections
The main sources of bacteria in the air
What are emerging infectious diseases (EIDs)?
Old diseases that no longer exist
New or changing diseases that are increasing in incidence or have the potential to increase soon
Diseases only found in animals
Diseases caused by poor hygiene
Which of the following is an example of a new, mutated strain of a pathogen causing emerging infectious disease?
Staphylococcus aureus MRSA
E. coli O157:H7
Ebola
Which of the following best illustrates emerging infectious diseases appearing in new geographic locations?
E. coli O157:H7 in contaminated food
Hantavirus and Malaria
Which factor can contribute to the emergence or re-emergence of infectious diseases due to changes in host immunity?
Which scenario illustrates the emergence of infectious diseases due to hosts inhabiting new locations?
SARS, Ebola, Coccidioidomycosis, and Venezuelan hemorrhagic fever appearing in regions where their animal hosts or vectors have newly established populations
How can changes in animal populations contribute to the emergence of infectious diseases?
Increased animal populations can lead to more human contact and higher transmission of zoonotic diseases, such as more deer leading to more Lyme disease
How can the use of antibiotics or pesticides contribute to the emergence of infectious diseases?
By enhancing the effectiveness of all treatments, reducing infections
By creating a balanced ecosystem that prevents disease spread
By increasing the populations of resistant organisms, leading to antibiotic- or pesticide-resistant infections
What is epidemiology?
The study of individual body systems
The study of how diseases spread and affect populations
The study of bacteria under a microscope
The study of hospital infections only
Epidemiology uses statistics to study:
DNA and cell structure
Patterns of disease — who, where, and when people get sick
The chemical composition of pathogens
Only genetic diseases
A descriptive study in epidemiology focuses on:
Testing new medicines
Collecting data after an outbreak to describe who, where, and when it occurred
Comparing sick vs. healthy people to find causes
Following groups over time to track illness
An analytical study is used to:
•analyze a particular disease to determine its probable cause
Describe the symptoms of a disease
Test treatments in a lab
Identify bacteria using microscopes
In a case-control method, researchers:
Follow exposed and non-exposed groups over time
Compare people with and without the disease –to see if any factors like age, gender play a role
Test new medicines
Describe symptoms after an outbreak
A cohort med follows:
People with different diets
Two groups — one exposed and one not exposed — to see who gets sick
Only patients who already have a disease
Only people in hospitals
Which is an example of a cohort study?
Testing how a vaccine affects infection rates
Following people who got blood transfusions vs. those who didn’t
Comparing sick vs. healthy people after an outbreak
Studying everyone in one city who got sick
An experimental study involves:
Observing natural disease spread only
Testing a hypothesis with a control and test group
Comparing disease rates between cities
Describing outbreak symptoms
What is the purpose of case reporting in public health?
To advertise new vaccines
To track and control outbreaks by reporting certain diseases
To record only deaths from diseases
To study the genetic code of pathogens
What does CDC stand for?
Control Doc Cases
Centers for Disease Control
What does MMWR stand for?
Monthly Medical Warning Report
Morbidity and Mortality Weekly Report
Major Medical Weekly Record
Microbe and Mutation Weekly Review
What is the morbidity rate?
The number of people who die from a disease
The number of people affected by a disease in a given period of time in relation to total population
The number of people vaccinated
The total number of hospitals in a region
What does the mortality rate measure?
How quickly a disease spreads
The number of people who die from a disease
The number of people exposed to a disease
The number of new hospitals built
What does NIH stand for?
National Institute of Hospitals
National Institutes of Health
New International Health Agency
National Infection Headquarters
What does WHO stand for?
World Health Organization
Western Health Office
Worldwide Hospital Operation
World Hygiene Organization
In hospitals, which of the following best describes the chain of transmission for infections?
The methods used to sterilize medical equipment before procedures
The steps involved in the healing process of an infection
The mechanisms through which pathogens are transmitted—such as via medical personnel, specialized care units, catheters, or needles
Which study design involves comparing two populations—one exposed to a potential disease-causing agent and one not exposed—to determine the incidence of disease?
What is a health care–associated infection (HCAI)?
