'Major breakthrough': UK researchers find drug that cuts Covid death rate

Giving low doses of the generic steroid drug dexamethasone to patients admitted to hospital with Covid-19 reduced death rates by around a third among those with the most severe cases of infection, trial data showed on Tuesday.The results, described as a "major breakthrough" by scientists leading the UK-led clinical trial known as RECOVERY, suggest the drug should immediately become standard care in patients treated in hospital with the pandemic disease, the researchers said.
