The cities of San Francisco and New Orleans on Aug. 12 ordered patrons to show proof of Covid-19 vaccinations to enter restaurants, gyms and other venues, joining New York in a severe step designed to contain the fast-spreading Delta variant.

New York City will become the first major U.S. city to require proof of Covid-19 vaccination for customers and staff at restaurants, gyms and other indoor businesses as the country enters a new phase of battling the highly contagious Delta variant.

The U.S. National Restaurant Association will remove a suggestion from its operating guidance for restaurants that says fully vaccinated people should still wear masks indoors, following new advice from the U.S. Centers for Disease Control and Prevention (CDC) on May 13.

New York Governor Andrew Cuomo unveiled a plan to revive New York City’s renowned arts scene from its pandemic-induced dormancy and also allowed city restaurants to reopen their indoor dining areas sooner than previously announced.

Several U.S. governors, from the coastal states of New Jersey and California to the heartland of Iowa and Ohio, acted to restrict gatherings and boost face-coverings in confronting a coronavirus surge they warned is out of control.

Global coronavirus cases rose by more than 400,000 for the first time, a record one-day increase as much of Europe enacts new restrictions to curb the outbreak.

To effectively create immunity to Covid-19, we need to educate to vaccinate.

New Jersey and California took a big step toward letting businesses resume their pre-pandemic lives, by allowing restaurants to begin limited indoor dining, as coronavirus cases abated nationwide even as some new hotspots emerged.

California reported a record increase of more than 11,800 new cases of Covid-19, according to a Reuters tally of county data, as the Trump administration pushes for schools to reopen to help businesses return to normal.

The World Health Organization said airborne transmission of the novel coronavirus can occur during medical procedures that generate aerosols.
