Pathogen A has an ID50 of 10 cells and an LD50 of 10,000,000 cells. Pathogen B has an ID50 of 10,000 cells and an LD50 of 20,000 cells. From this information, we can determine that: ○ Pathogen A has higher infectivity but lower virulence than Pathogen B. ○ Pathogen A has lower infectivity but higher virulence than Pathogen B. ○ Pathogen B has higher infectivity but lower virulence than Pathogen A. ○ Pathogen B has higher infectivity and higher virulence than Pathogen A.

Below are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)
Which of the following pathogens is the LEAST virulent? 1. Microbe B, ID50 = 1,000 cells 2. Microbe D, ID50 = 10 cells 3. None of the other four answers (Cannot be determined from information provided) 4. Microbe C, ID50 = 100 cells 5. Microbe A, ID50 = 100,000 cells
The equation for R0 of a pathogen transmitted by density-dependent mode of transmission is: R0 = β S/ y Calculate R0 for a system witH β = 0.002, S = 500, and y = 0.2. Additionally, derive the expression for the Threshold Density of susceptibles and calculate its value given the parameter values above. Please show steps.
In an epidemiological study with human subjects, the relationship between the independent variable and the dependent variable always suggests that: Answer choices one does not cause the other. correlation always equals causation. one caused the other. correlation does not always equal causation.

You are an analyst in the Florida Department of Health and you are tasked with using the SEIR model for computing the spread of various infectious diseases in Florida. What does the SEIR acronym stand for?
Consider the formula in Section 3 of SimUText's How Diseases Spread that relates the critical immunization threshold, pc and the Basic Reproductive Number R0. Recall that the critical immunization threshold is the minimum proportion of the population that must be vaccinated to establish herd immunity; and The Basic Reproductive Number is the average number of individuals infected by an infected individual, if the whole population is susceptible. What happens to the critical immunization threshold as R0 gets larger (more individuals are infected by an infected individual)? Consider the formula in Section 3 of SimUText's How Diseases Spread that relates the critical immunization threshold, pcand the Basic Reproductive Number R0. Recall that the critical immunization threshold is the minimum proportion of the population that must be vaccinated to establish herd immunity; and The Basic Reproductive Number is the average number of individuals infected by an infected individual, if…

of the federal agencies that regulate epidemiological risk; which one allows more risk, OSHA or the EPA? why?
Which of the following statements is false?a) A disease with a long incubation period might spread extensively before an epidemic is recognized.b) A person exposed to a low dose of a pathogen might not develop disease.c) The young and the aged are more likely to develop certain diseases.d) Malnourished populations are more likely to develop certain diseases.e) Herd immunity occurs when a population does not engage in a given behavior, such as eating raw fish, that would otherwise increase their risk of disease.
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…
