Dr. Anthony Fauci

President Trump, who has for months been at loggerheads with public health experts on how best to contain the coronavirus pandemic, on Monday called Dr. Anthony Fauci a "disaster" and complained that Americans are tired of hearing from "these idiots," according to media reports of a call between Trump and campaign staff.

Miami-Dade County says it will not fully comply with a decision by Florida Gov. Ron DeSantis to lift most restrictions aimed at controlling the spread of coronavirus, saying it's too soon to safely reverse the precautions.

County Mayor Carlos Gimenez, speaking Tuesday with local medical advisors, and in a conference call with White House Coronavirus Task Force Coordinator Dr. Deborah Birx and the nation's leading infectious disease expert, Dr. Anthony Fauci, said that the number of COVID-19 cases in the county has declined because it has reopened very slowly.

Nine drug companies pledged Tuesday that they will not submit vaccine candidates for FDA review until their safety and efficacy is shown in large clinical trials. The move is intended to bolster public confidence amid the rush to make a COVID-19 vaccine widely available, and counter fears of political pressure to have a vaccine before the November presidential election.

The Centers for Disease Control and Prevention has asked states to prepare to distribute a potential coronavirus vaccine as soon as late October, according to a series of planning documents sent to public health officials last week.

A coronavirus vaccine could be ready for distribution by the end of the year, and distributed to Americans in 2021, the nation's top infectious disease specialist told lawmakers Friday.

In a grim accounting of the coronavirus's progress in the United States, another milestone was reached Wednesday: more than 50,000 new cases reported in a single day.
