The Associated Press news agency has analysed protests over the past few days and found that demonstrations over the killing of George Floyd had been held in every one of the 25 US communities with the highest concentrations of new cases.
There are growing fears that the tightly packed streets and squares with people often not even wearing and face masks could lead to a spike in the number of new cases.
There are currently 1.8 million confirmed cases of coronavirus in the US – with more than 106,000 deaths.
