- Whenever ice cream sales are high, polio cases are high. And whenever ice cream sales are low, polio cases are low. Ice cream sales and polio incidence are correlated, but there is no direct causal link between polio cases and ice cream sales. In other words...? A. there is something else that causes both the changes in ice cream sales, and the changes in polio cases over the year. B. eating ice cream causes people to visit swimming pools where polio is transmitted. C. having polio causes people to eat more ice cream, but eating ice cream does NOT cause polio.refer to the provided image 80. Which of the following is represented by the x-axis of the provided epidemic curve?A. Asymptomatic timeB. Generation time C. Incubation periodD. Natural history 81. What type of epidemic is evident on the given epidemic curve?A. IntermittentB. Point-source C. ProgressiveD. PropagatingThe Zoomland epidemic does not mimic a real epidemic in every respect. What is ONE way the Zoomland epidemic is not an entirely realistic simulation? A. In the Zoomland epidemic we could tell who had interacted with whom (contact tracing). In real life there is no way to do any contact tracing. B. In the Zoomland epidemic people interacted randomly with others. In real life people interact much more with some members of the population than others. C. In the Zoomland epidemic, transmission only occurred when a person came into contact with an infected person AND a suitable vector. In real life some diseases do not require a vector for successful transmission.
