Chapter 1, Problem 5CTQ
You are a scientist researching West Nile virus, a mosquito-borne pathogen. You note that the number of cases of West Nile disease in your county skyrocketed to their highest levels ever this past summer, which also was the wettest summer in 100 years. Using the scientific method, develop a sound hypothesis explaining the increase in disease cases last summer and a method for testing this hypothesis.

- 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 choleraearrow_forwardConsidering the case study example of the Zaire ebola virus epidemic, select the correct statement. Zaire ebola virus epidemics most often last for more than 10 years. Zaire ebola virus does not occur in human populations. Zaire ebola virus epidemics always die out. O Zaire ebola virus has been uninterruptedly circulating in humans since 1976.arrow_forwardInterpreting Data The graph shows the number of cases per week of Zika, Dengue, and Chikungunya virus in Puerto Rico during the period from November 1, 2015 to April 14, 2016.

- History may not be your favorite subject, especially learning about a bunch of long-dead scientists who made discoveries that we now take for granted. With an open mind, you may actually find the information interesting and learn a few things you didnt know before. During your examination of the topics in this chapter, consider the following: Do patterns exist for disease outbreaks, treatment, eradication, and recurrence?arrow_forwardWhich of the following is a pyrimidine (one type of nitrogenous base) that is commonly found in all DNA molecules, but is not commonly found in all RNA molecules? adenosine cytidine thymine guanine uracil If retroviruses like HIV follow the historical pattern of a parasite adapting to a new host species (like syphilis in Europe over the past 500 years), then rapid virulence initially would likely be followed by: increasing virulence of the parasite, and decreasing resistance of the host increasing virulence of the parasite, and increasing resistance of the host decreasing virulence of the parasite, and decreasing resistance of the host decreasing virulence of the parasite, and increasing resistance of the host all of the above outcomes would be equally likelyarrow_forwardFor a potentially serious disease like bubonic plague,vaccines are not routinely recommended for the generalpopulation; why not? Identify the public healthmeasures used to control plague.arrow_forward
- Is the environmental risk posed by DDT an acceptable cost in the battle to control malaria? Malaria is a life-threatening disease caused by parasites that are transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable. In 2017, there were an estimated 219 million cases of malaria in 87 countries.arrow_forwardSub-Saharan Africa is epicenter of two major pandemics: HIV/AIDS and Tuberculosis (TB). Although people living with HIV/AIDS can receive antiretroviral therapy and live many years, they are extremely susceptible to co-‐infections. Even with medication, the combination of HIV/AIDS and TB is often fatal. In Swaziland, a small country nestled in Southern Africa, the total population in 2010 was only 449,900 people. Of that population, the total number of people living with HIV/AIDS was 33%. In 2010 the total number of deaths in Swaziland was approximately 13,000. In the same year the number of HIV-related deaths was reported as 9,300. Question: What was the cause-specific mortality rate from HIV per 1000 people? (round to the nearest whole number)? What is the proportionate mortality from HIV/AIDS in this population? (give your answer as a percent and round to the nearest whole number)arrow_forwardBelow are statements about symbiosis. Choose the correct responses. ( Only pick one answer per [ ] ) ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when two organisms both benefit from a relationship. One example of this you will view is lab is ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"] . ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when one organism benefits, while the second organism is not harmed, and does not benefit. ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when one organism benefits while the second organism is harmed. In lab you will explore ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"] as an example of this relationship.arrow_forward
- In 2005 a typhoid outbreak in Delmas, South Africa, prompted the widespread testing of food andwater sources to ascertain the origin of the outbreak. However, the origin of the outbreak couldnot be definitively traced. In your view, what could have been the possible reasons for this state ofaffairs?arrow_forwardChoose the false statement: O A contaminated catheter might be an example of an iatrogenic infection. The size of an inoculum introduced into the host has little to do with the success or pathology of an infection. O A zoonosis is an infectious disease or pathogen that has crossed over from an animal species and begun to infect humans. O Vertical infections are those transferred from mother to child either during birth or via breastfeeding. Question 21 Choose the false statement below. O Long term consequences to a host that have been caused by infectious disease (such as heart disease after septicemia) are termed sequelae. OPortal of exit" refers to the way in which the immune system destroys an infection, or how antibiotics can be used to kill invading bacteria. O Whether or not a person is a susceptible host for disease is determined in part by where that person lives and how that person is employed.arrow_forwardAs an outbreak of disease spreads in a relatively isolated community, some contract tracing occurs, and likely transmission events identified. Contract tracing determines that a sample of 10 infected individuals caused the following number of secondary cases: (look at the attached image) -Calculate the average number of secondary cases and create a ‘who acquires infection from whom’ matrix of R0 numbers. Use this matrix to calculate the overall R0 number for the population.arrow_forward
