Mr. Trump’s supporters, for their part, were eager to wish him well, and move forward.
Mira Katerinos, 59, a registered nurse in Waukesha, Wis., said she was a strong supporter of the president — and that, to her, he appeared strong physically and mentally. “Trump will probably do more campaigning with Covid than Biden with no Covid — he hardly seems to be campaigning at all,” she said, repeating a common Trump campaign criticism of his opponent’s schedule. She said she saw no problem with Mr. Trump resuming rallies after recovering, which she expected him to do.
“Life has to go on,” she said.
In Clinton Township, Mich., Jared Maynard, also thought life would continue as usual. He said he would continue to knock on doors, trying to convince voters in the key county of Macomb that the president deserves re-election.
“For me, I’m already taking precautions, so I’ll wear my mask and try to social distance,” said Mr. Maynard, 40. “The president will put his health first and the campaign will move on.”
Politically, few voters expected Mr. Trump’s personal encounter with the coronavirus would shake his supporters’ faith in him.
Jeff Litscher of Stetsonville, Wis., said he thought — he “was naïve enough to think” — that some people might take down their Trump signs after the revelations, in Bob Woodward’s latest book, that the president privately admitted the risk of the virus while playing it down in public.
“But if anything, they have multiplied,’’ said Mr. Litscher, the host of a radio show in Wisconsin’s Northwoods who plans to vote for Mr. Biden.
Just as the Trump signs multiplied around the country, many people spoke of divisions multiplying, too.
