Reuters examined 220 counties where 95% of the votes were counted.
Mr Trump has also won states with some of the highest death rates from the virus, including Florida and Texas, which had lax or slow responses to Covid-19, or which reopened too quickly, resulting in a increase in cases.
The prominence of the pandemic in elections, both as a campaign issue and because of the logistical challenges it presented to voters and candidates, is one of the defining features of the 2020 electoral cycle.
Joe Biden’s campaign has made the Trump administration’s response to the coronavirus a central part of its message – particularly the appalling number of deaths across the country.
The Trump campaign focused on the economic implications of the country’s lockdown, with the president continually downplaying the severity of the disease, demanding state governors reopen their economies, later repeating that the United States was “turning a corner” on the end of the pandemic. .
As Biden’s team called off in-person events and door-to-door campaigns to prevent the spread of the virus, the Trump campaign has enthusiastically revived its rallies – after a two-month hiatus – with little in the way of giving pay attention to social distancing and wearing a mask.
Widely referred to as mass-market events, research has directly linked peaks in coronavirus cases to the weeks following a local Trump rally.
Minnesota health officials were able to trace two dozen cases to the events of the campaign. The same trend has been documented in Minnesota, Pennsylvania and Wisconsin, with a study indicating that the gatherings resulted in an additional 30,000 cases.
Even after contracting Covid-19 himself in October, the president continued to downplay its severity and ignore advice on wearing the mask to stop the spread of the disease.
And this is a potential explanation for the president to do better in counties with higher death tolls from the virus – they may also be home to some of his more enthusiastic supporters.
Campaign events continued into the election, with the president hosting up to five events a day in five different states.
The United States surpassed 100,000 new cases of the coronavirus in one day on Wednesday – the highest amount recorded since the start of the pandemic.
To date, there have been 9.52 million cases of Covid-19 and more than 233,000 officially recorded deaths.
