A police officer and a PCSO were allegedly coughed on and had saliva wiped on them by somebody claiming to have Covid-19.
The incident happened at around 8pm on Friday as officers attended an address in Worksop.
Brian McDonald, of Worksop, has been charged with two counts of assaulting an emergency worker and remains in police custody.
The 47-year-old is scheduled to appear at Nottingham Magistrates’ Court on Monday morning.
Inspector Nick Butler, of Nottinghamshire Police, said: “This is a particularly challenging period to be working as an emergency worker and incidents like this really highlight the risks we all face.
“We know when we go to work each day we are taking risks to keep everyone safe but we also have families to go home and this really adds to their concerns.“
