Cholera Case Study Questions And Answers 100% All Verified 2022 Concerning John Barnes, how was cholera communicated? What were the modes of disease transmission? What is the correct epidemiological term for the modes of transmission that were identified? - CORRECT ANSWER-John Barnes contracted cholera through his infected sister. Her infected clothing was sent to Barnes without being washed; he contracted cholera upon opening the box and touching the clothing. Fomite transmission was involved in the actual transfer. How long is a fortnight? - CORRECT ANSWER-Two weeks In the examples or circumstances presented, what were the various modes of transmission stated or at least alluded to? Which were correct? Which were incorrect and why? What role did personal hygiene and sanitation (including food preparation and hand washing) play in the transmission of the disease and continuation of an outbreak? - CORRECT ANSWER-Primary mode of transmission was person-toperson contact. Effluvia given off from a sick person was also mentioned as a mode of transmission. Snow hypothesized that affection began first with the alimentary canal. Thus, personal hygiene and sanitation played a role in transmission because people were in contact with infected individuals and did not wash their hands properly. When they prepared or ate food, cholera was transmitted to the stomach and bowels. Bed linens that hosted cholera "evacuations" also were a mode of transmission. Infected water was seen as a transmitter. Several instances of causal association were presented or alluded to in the examples presented in the case. List the various instances of association you can identify from the examples or situations presented in the case. What role did social class, poverty, and housing arrangements play in association? What role did water play in association? - CORRECT ANSWER-Association was found in the following cases: food infected by those who had cholera; water infected by feces or cholera evacuations that was then used for cooking and drinking; involuntary passage of evacuations from infected individuals; poverty was found to be a major risk-factor for the spread of disease because poor people lived in cramped conditions where cooking and eating took place in the same room as the sick person; and lack of sanitary conditions including hand washing. Describe the disease cholera as presented in the Snow case. Describe cholera as it is known today. - CORRECT ANSWER-Cholera, as described by Snow, was a disease that was first introduced at a sea port, and was then spread though human interaction. Its transmission could occur through communication from a sick to a healthy person. Snow hypothesized that a cholera agent was ingested and then reproduced in the stomach and bowels. The agent served as an irritant to the stomach, or else it withdrew fluid from the blood circulating in the capillaries. It was characterized by a short incubation period and fast spreading.
