“Jill and I send our thoughts to President Trump and First Lady Melania Trump for a swift recovery,” Biden said in a social media statement on Friday morning.
“We will continue to pray for the health and safety of the president and his family,” he added.
COVID-19 is the disease caused by the CCP (Chinese Communist Party) virus.
Several hours later, at about 12:30 p.m., Biden said on Twitter that he and his wife both tested negative for the new disease.
“Thank you to everyone for your messages of concern. I hope this serves as a reminder: wear a mask, keep social distance, and wash your hands,” he wrote.
Biden was scheduled to campaign in Michigan later Friday.
Though older people and those with serious underlying health issues are more at risk of developing serious cases of COVID-19, most people who contract the illness end up recovering.
A small percentage of patients die.
The Trumps “are both well,” Sean Conley, physician to the president, said in a memorandum late Thursday.
The first lady said she and her husband “are feeling good.”
She postponed all planned appearances and Trump scuttled plans to travel to Florida for an Oct. 2 rally.
