San Francisco remains at the red level for now, but that could change: Its case numbers are low enough to merit a move to the less-restrictive orange tier. It is awaiting approval from the state’s health department.

1:45 p.m. FDA said to be readying new vaccine standard: The Food and Drug Administration is expected to spell out a tough, new standard for an emergency authorization of a coronavirus vaccine as soon as this week that will make it difficult for any vaccine to be cleared before Election Day, the Washington Post is reporting.

He listed mask-wearing, avoiding crowds, social distancing. What’s important, he said, is that the virus can be transmitted and people should keep their guard up.

12:29 p.m. San Mateo County to immediately allow more reopenings: Now that San Mateo County has moved to red classification on the state’s progress monitoring system, it will immediately adopt less restrictive state guidelines for reopening sectors, including indoor dining, museums and houses of worship operating at 25% capacity and gyms opening indoors at 10% capacity, said Preston Merchant, a county spokesman.

Counties move into less restrictive tiers based on meeting goals for case rates and positive test rates.

10:38 a.m. Public uptake a problem for contact tracing apps: Mobile apps tracing new COVID-19 cases were touted as a key part of Europe’s plan to curb the coronavirus spread. Virus cases are surging again and the apps have not been widely adopted due to privacy concerns, technical problems and lack of interest from the public, the Associated Press reports.

10:28 a.m. Trump’s ‘amazing’ ‘incredible job’ on the coronavirus: Shortly before Johns Hopkins University announced a milestone 200,000 U.S. deaths, the world’s highest COVID-19 toll, President Trump told a WJBK Fox 2 interview that he’s “done an amazing” job handling the coronavirus. “We’ve done an incredible job between the ventilators and now the vaccines and everything else and the therapeutics” he said.

8:11 a.m. New confidence in economy: Most Americans view the nation’s economic situation as bleak, but a rising percentage also see signs of stability six weeks before Election Day — if not reasons for optimism, according to a new poll from the Associated Press-NORC Center for Public Affairs Research. The poll finds 60% of Americans describe the national economy as poor and 40% deem it good. April and May were low points, when just 29% called the economy good as the pandemic took hold.
