Reports of a powerful treatment for the new coronavirus has brought waves of skepticism among U.S. doctors. Trial results announced on Tuesday showed dexamethasone cut COVID-19 death rates by around a third. British researchers announced the results and said they would publish full study details as soon as possible. U.S. physicians said; “we have been burned before, not just during the coronavirus pandemic but even pre-COVID". Doctors said they have heard of "exciting results" in prior tests, but that under closer investigation the data are not as convincing. According to Reuters, pressure to find a cure or vaccine has accelerated the typical process of studying medications.
