Name: Jasmeen & Pari SBI3U Date: ______________ Case Study: Measles & Immunizations Measles is a viral infection that causes high fever and a cough. A vaccine for measles has been available since the early 1960s. The World Health Organization (WHO) tracks data on the incidence of measles as well as the percentage of people around the world who receive the measles vaccine each year. In this study, you will examine the relationship between the percentage of people who are immunized and the incidence of measles. Part 1: Data Organization Organize the data provided (to the right) into a graph. Use the following instructions (this is also the marking scheme for the graph): o o o o o Plot year on the x-axis, plot incidence of measles on the left y-axis, and plot percent immunized on the right y-axis. Use data points to make a double line graph. You will need 2 colours and you will need to make a legend Make sure your graph is neat and accurate Make sure you provide an appropriate title for your graph Make sure that you use consistent scaling on your axes, and make sure that your axes are labeled! Part 2: Data Analysis Please type your answers here. 1. Analyze your graph and explain the relationship between the % of people immunized and the incidence of measles. [1] 2. What are vaccines and how do they work to protect people against viruses? Why is it not always possible to develop effective vaccines? (e.g. for HIV or the influenza virus) [3] 3. Some individuals are against mandatory vaccinations (immunizations). How would you respond to people that might refuse immunizations? Use your data and graph to justify your response. [2] 4. Visit the World Health Organization website: Disease outbreaks by year or https://www.who.int/emergencies/disease-outbreak-news a) Select a disease outbreak year and choose a viral disease (not a bacterial one) and research its cause, symptoms, prevention, and treatment. b) Summarize the disease outbreak (i.e. where, how many etc…) and the WHO recommendations or advice.
