The United Kingdom reported its highest number of new daily Covid-19 cases since June 12, with 1,522 new infections on Thursday, according to government data.

The number of new confirmed cases on Thursday is an increase from 1,048 new cases reported Wednesday and 1,184 new cases reported Tuesday.

The cumulative total of coronavirus cases has risen to 330,368, according to government data. A further 12 deaths have been recorded, bringing the UK's official death toll to 41,477.

Meanwhile, the country removed the Czech Republic, Jamaica and Switzerland from its list of “travel corridor” countries, meaning people arriving from those nations will now be required to quarantine for 14 days, transport secretary Grant Shapps said in a series of Thursday tweets.

The UK has also added Cuba to the list of countries exempt from the 14-day quarantine.

The new restrictions will go into effect for people arriving after 4 a.m. local time on Saturday (11 p.m. ET Friday).
