Malaria testing ~ Early diagnosis and treatment of malaria are necessary components in the control of malaria. The gold-standard light microscopy test has high sensitivity but is a relatively time-consuming procedure especially during epidemics and in areas of high concentration. A new Cyscope fluorescence microscopy test has been developed and gives results in less than 10 minutes. The test has a specificity of 98.3% and a sensitivity of 94.96%. Round all answers to 4 decimal places. 1. Given a base rate of 11% and a theoretical population of 10,000, construct the contingency table for this scenario. Test Positive Test Negative Total Have Malaria Do not have Malaria Total 10,000 2. If we randomly selected an individual from this population, what is the chance the person would test positive for malaria? 3. What proportion of the people who test negative for malaria would we expect to actually have the disease? 4. What is the chance a person from this population who tests positive for malaria will not have the disease?
