- What is meant by the “American approach” and the “precautionary principle”? Relate this to either DDT or Agent OrangeQuestion 20 Medical microbiology laboratories are using molecular methods more and more to facilitate pathogen identification. What are the advantages of molecular methods, compared to traditional cultures? Question 20 options: a) Molecular methods provide rapid, quantitative results even for pathogens that have mutated b) Molecular methods are associated with increased sensitivity and yield rapid results c) Molecular methods are associated with increased sensitivity, and yield rapid results related to susceptibility testing d) Molecular methods yield results that remain positive for a long period of time, and are resistant to contamination with commensal organismsWhich 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
- What can be done on a "Macro level" to solve the issue of COVID-19 Pandemic?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 strainsThe 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: A. changes in populations or behavior of reservoir hosts or intermediate hosts B. microbial genetic mutation and viral genetic recombination or assortment C. environmental factors such as an increase in precipitation D. all of the above E. none of the above
- "Early in the COVID-19 pandemic, some argued that comparable numbers of people caught bad strains of the influenza virus (causing the viral flu); thus, by extension, the restrictions imposed on society for COVID-19 were unduly burdensome. Based on our discussion in class, which arguments could be made to refute this argument. " "While an average of 31 million people catch the viral flu each year in the US (compared to 16 million COVID-19 cases so far), the mortality rate from the flu seems to be perhaps 8 to 24 times lower than for COVID-19." "Fewer people have caught COVID-19 than catch the viral flu in a given year, but the comparison is not entirely fair since we are not restricting social gatherings or wearing masks during viral flu seasons. A fair comparison would be what would have happened with COVID-19 infections if normal year practices were carried out. " More than twice the number of people in the US have caught COVID-19 than catch the flu virus in a…Future Challenges think about what our course would have been like before the pandemic. It would be predictable, without drama and relatively simple in so many ways. Since then we’ve been faced with an ever-changing and challenging daily environment. Social distancing, sanitizers, masks, toilet paper shortages, online education, sports and concerts cancelled, stock market craziness and so many other issues have taken over. Our fellow healthcare professionals are stressed beyond words, our hospitals are not prepared for the potential number of patients needing intensive care. At the time of this writing public health experts are expressing grave concern over what they claim is an overall lack of leadership and quick response on the part of government to address this pandemic. Now, politics has become a major factor. So much happening……so much to consider….Please write a reflective essay that discusses future challenges in our healthcare system. Reference at least three talking points…What is the significant role of Science in addressing the COVID-19 Pandemic?

Infectious disease Emerging infectious disease Pathogen HelminthIn a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 2,000, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 150. Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium? There is no way to know given the information provided Both infections are equally likely Donoteatum thisbacterium Parasiticum mucoides
