The US capital is moving ahead with the second phase of its reopening Monday, as city officials credited months of social restrictions with blunting an anticipated spike in Covid-19 infections, AP reports.

Mayor Muriel Bowser announced that playgrounds, libraries, gyms and nail salons in Washington, DC, will be able to reopen on a limited basis. All non-essential businesses will be allowed to let customers inside at up to 50 per cent capacity. Restaurants will be able to seat diners indoors, also at 50pc capacity.

Theatres, cinemas and concert venues will remain closed but they can apply for a special waiver from the district government. Public pools will be reopened on a limited basis, although Bowser said earlier this week that it may take a few weeks to properly prepare the facilities.

Indoor gatherings of up to 50 people will be allowed. Houses of worship can hold services for 100 people or 50pc capacity whichever number is smaller — but Bowser said the city's health department is recommending that choirs not yet perform.
