The United States has recorded its biggest weekly rise in Covid-19 deaths since August, increasing 32 per cent from the previous week to average about 1,500 people per day, according to a Reuters analysis of state and county reports.

New cases rose 13pc in the week ended Nov 22, or an average of more than 168,000 per day.

Ahead of the Thanksgiving holiday this Thursday, at least 23 states have announced new restrictions to try to slow the spread of the virus but so far only New Mexico has issued a stay-at-home order.

Cases rose by 90pc in New Mexico last week, the biggest percentage increase in the country, followed by Virginia at 62pc and Arizona with a 50pc increase.
