A key recommendation for controlling the spread of COVID19 is to "test, test, test!". If we were able to test everyone using a test that was both 100% sensitive and specific for the disease, we would have no falsepositive (wrong identification of people without the infection) and no falsenegative (cases of infection that are missed) though no test is perfect. Based on data collected on 10000 people so far, it is known that: For people who are infected with COVID-19 virus, 98.9% of them test positive. For people who have symptoms but are not infected with the COVID-19 virus, 4% of them test positivewhich is known as false positive It is estimated that currently, around 0.3% of people have been infected with the virus.
