Scientists Say They're Almost Ready With a Pill to Treat COVID
Researchers are developing a pill they say might allow people to treat their COVID-19 while limiting its transmission to others — and it might be ready by the end of the year. Three antiviral treatments for the disease are currently undergoing clinical trials, according to NBC . The treatment itself would likely be a regimen of daily pills taken orally that fight COVID early after diagnosis. Thes
