A major study shows the experimental drug Remdesivir to be effective in fighting the new coronavirus, American health officials say. The United States National Institutes of Health led the study. It compared treatment with Remdesivir to usual care in 1,063 hospitalized coronavirus patients around the world. Anthony Fauci is the NIH’s leading infectious disease expert and a member of President Donald Trump’s COVID-19 task force. Dr. Fauci said the Remdesivir reduced recovery time. He said patients who received Remdesivir recovered on average four days earlier than those who got usual care. “What it has proven is that a drug can block this virus,” Fauci said. “This will be the standard of care.”
