Reasons for hope: The drugs, tests and tactics that may conquer coronavirus

With much of the world living in lockdown, the spread of the new coronavirus, SARS-CoV-2, that was first detected in China late last year is beginning to slow in some places. As of April 12, 1.8 million had been infected and 115,000 killed by COVID-19, the disease caused by the virus. While a safe, effective vaccine is still more than a year away, researchers are rushing to repurpose existing drugs and non-drug therapies as well as testing promising experimental drugs that were already in clinical trials. Even moderately effective therapies or combinations could dramatically reduce the crushing demand on hospitals and intensive care units, changing the nature of the risk the new pathogen represents to populations and healthcare systems. New drugs, together with new diagnostics, antibody tests, patient- and contact-tracing technologies, disease surveillance and other early-warning tools, mean the anticipated next "wave" of the global pandemic does not have to be nearly as bad the first.
