Consider modes of disease transmission. Describe how the spread of a disease would differ if the pathogen is airborne, foodborne, waterborne compared to a disease that requires physical contact like a handshake. How would spread differ if sexual contact was required rather than a handshake? How would the results differ if you have only a 50% chance of contracting the disease after being exposed due to differences in host factors? How does this relate to the concept of susceptibility? How would the results differ if 80% of the class were vaccinated against this 'infectious disease'? Would transmission patterns differ? What public health measures could be put in place to combat a disease which spreads via direct contact? Are these different to measures useful to curb spread of a vector-borne disease? How?

Step 1
Modes of disease transmission: - Airborne: The disease spreads through the air, usually via respiratory droplets or aerosols. Examples include influenza and tuberculosis. - Foodborne: The disease spreads through contaminated food. Examples include salmonella Show more…

2.3 Infectious Cycles and Disease Transmission Please read the short passage and fill in the blanks with the appropriate words that explain how epidemiologists describe diseases in a population. Drag word(s) below to fill in the blank(s) in the passage. Epidemiologists study the movement of diseases in a population. They describe [blank] diseases that are constantly in a(n) [blank]. These diseases are generally seen at a [blank] rate. When several cases appear over a short time, a(n) [blank] is declared; if it spreads and affects people throughout the [blank], it is called a(n) [blank]. etiologic individual community endemic vector zoonotic world epidemic high low pandemic

Multiple Choice. Circle or mark the correct answer choice (s). 1. What is the method of transmission used in this mock epidemiology experiment? A. indirect contact B. direct contact C. droplet transmission D. biological transmission E. vehicle transmission 2. A tick bites a person who subsequently develops a fever and "bull's eye" rash. What type of transmission would this be? A. mechanical vector transmission B. biological vector transmission C. direct contact transmission D. vehicle transmission E. droplet transmission 3. What is your conclusion if the plate did not show the presence of the pathogen? A. The individual was not been infected by the pathogen. B. The individual will have symptoms. C. The individual could be a carrier for the disease. D. The individual is immune to the disease. E. The individual was never exposed to the pathogen.

Use the following terms to best match the correct statement/definition. Infectious disease epidemiology opportunistic pathogen true pathogen Sporadic cases endemic infections epidemic pandemic zoonotic disease communicable disease 1. A patient is feeling the onset of the flu, by feeling fatigue . 2. There was a of bubonic plague back in the 14th century. 3. This is a disease that have isolated infections in a particular population. 4. The patient came in with manifestations of rabies. This is described as what type of disease. . 5. You are working with a patient who has influenza, you must wear a mask if working within 3 feet due to droplet precautions. This is an example of what type of disease . 6. These are routinely detected in a population or region. . 7. If you do not wipe correctly after a bowel movement, this may introduce E. coli into the urogenital tract. This is an example of . 8. This does not require a weakened host to cause disease a. An example is the common cold. 9. Monitoring and controlling disease occurrence to promote public health.
