In the absence of a medical cure, testing is the most critical factor in managing the spread of the Coronavirus. Testing allows infected people to know that they are infected. This can help them receive the care they need, and it can help them take measures to reduce the probability of infecting others. People who don’t know they are infected might not stay at home or might infect others in their homes, and thereby risk infecting others. Testing allows us to understand the spread of the disease and to take evidence-based measures to slow down the spread of the disease. It is imperative that we escalate testing, isolation and contact tracing efforts. Those who test positive for Covid-19 must be isolated and those in contact with them, traced.
