The epidemiological or disease triangle is a model of disease causation that proposes three factors contribute to an outbreak - an agent that causes the disease, a susceptible host, and an environment that brings the host and agent together. Some general changes within these three factors that may cause an infectious disease to emerge include: O A. changes in populations or behavior of reservoir hosts or intermediate hosts O B. microbial genetic mutation and viral genetic recombination or assortment O C. environmental factors such as an increase in precipitation O D. all of the above O E. none of the above

According to the natural history of disease model, the time before the precursors of disease and the host interact is called the period of: A. Prepathogenesis B. Pathogenesis C. Primogenesis D. B and C
The following are the limitations of Koch's postulates EXCEPT: A. some pathogens cannot grow on artificial media and therefore cannot be identified as the causative agent of the disease B. some diseases involve multiple pathogens which produce similar symptoms making it difficult to pinpoint the causative agent C. some diseases are host-specific and re-inoculation may pose ethical concerns D. some microorganisms are present in the body fluids of the infected animal which make them difficult to be cultured
Select all of the following that applies to the tradeoff between transmission and virulence that applies to many diseases. a) The tradeoff between transmission and virulence means that diseases always evolve to become more virulent. b) If greater virulence limits transmission, that disease will likely evolve to become less virulent than it could be. c) While making more copies of itself can increase the likelihood of transmission occurring, too much replication of the disease can make the host so sick it won't leave the house and spread the disease. d) A strain of a disease that replicates enough to be transmitted, but not so much that the host gets too sick to move, will be favored by natural selection over strains that either make the host too sick or do not replicate enough to be transmitted. e) If a disease can spread without making its host sick (e.g. when the host is asymptomatic), then the tradeoff between transmission and virulence…
Factors that impact the incubation period of a disease include all of the following EXCEPT: a. b. C. d. Invasive ability of the infectious agent The site of infection Dose Genetic predisposition
Which of the following describes "incubation period"? a. It is the time interval between entry of an infectious agent into the body and the appearence of the first symptoms and/or signs of the disease b. It is the time after recovery when a person can still harbor the infection c. It is the time interval through which an infected person is able to transmit the infectious agent to others d. It is the time interval between the onset of primary and secondary cases
Which of the following statements is correct? a. An individual who has been diagnosed with a communicable disease and those who may have been exposed to the infection are to be placed together in a unit away from others b. Serial interval is the interval between when an infectious agent invades a body and when the first sign or symptom appears c. Isolation should be maintained through the incubation period of a disease d. Healthy asymptomatic individuals suspected to have been exposed to an infection are quarantined through the length of the incubation period
This article highlights a young doctor at Elmhurst Hospital during the beginning of Covid-19 pandemic. Dr. Zikry is quoted as saying: “It’s become very clear to me what a socioeconomic disease this is...”. In addition, the textbook discusses the personal variables and socioeconomic status (SES) that are used to find patterns in disease (pp.112-118). What do you think Dr. Zikry meant by referring to the SES of his patients? Why was it important to find a pattern of personal variables and SES among the of victims of Covid-19 at the beginning of the pandemic?
The multifactorial causes of diseases often create philosophical problems in epidemiology. How does themultifactorial nature of disease impact:Disease classification, causal inference, and prediction?
What is disease causation theory? Define personalistic and naturalistic disease causation using films and/or readings.
Which of the following is NOT true about Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the disease it causes? Which option is the answer: 1. During Coronavirus Disease (COVID-19), a person is the most highly infectious for others during the period of peak viral load and symptoms 2. As it is transmitted through the global human population, the virus is highly genetically stable and does not change 3. Some people who become infected with SARS-CoV-2 will not develop signs and/or symptoms of disease 4. The severity of disease varies greatly, depending on age and/or underlying predisposing conditions 5. Emerging SARS-CoV-2 variants may sometimes be more transmissible than previous strains
Which of the following statements is correct? a. Serial interval is the length of time a person can transmit or shed an infectious agent b. Contamination of the drinking water source of a community by infectious agent(s) will likely result in a continuous common source epidemic c. It is not possible for people who have not shown symptoms of measles yet, to transmit measles infection d. Mary Mallon was a chronic carrier of Vibrio cholerae
