The mayor of Honolulu says the city will soon require patrons of restaurants, bars, museums, theatres and other establishments to show proof of vaccination or a recent negative coronavirus test, reports AP.

The rule takes effect from September 13 and is aimed at helping the city beat back a surge in cases from the highly contagious Delta variant.

Honolulu joins other cities such as New Orleans and New York that have implemented similar requirements.

Children under age 12 will be exempt.

Employees of the establishments will have to show proof of vaccination or undergo weekly testing. Businesses that don't comply could be fined or shut down.
