Problem: Using data and a wide variety of other evidence, analyse the spread of either influenza, measles, or COVID-19 from 1950 or earlier to the modern day. Where there is an increase or decrease in the figures use available evidence to explain why. This should include details of when new treatments or practices were discovered and how they reduced instances of disease and events that caused a change in the data. Analyse patterns in the disease to see which segments of society, if any, were more likely to be seriously ill or die from your chosen disease. This information could help the walk-in clinic plan for prevention and treatment going forward.
