A test centre patient who "deliberately coughed" over an NHS worker has been fined £1,000.
Gwent Police said the man found the incident at Newport's Rodney Parade testing centre in June "amusing".
The Crown Prosecution Service has previously warned that deliberate spitting and coughing at key workers would be treated as an assault.
Newport is currently the area with the fourth highest seven-day average number of cases, adjusted for population, in Wales with 39.4 cases per 100,000 people (as of 2pm on September 17, 2020).
Chief Superintendent Mark Hobrough said he was "pleased" to see the individual come to justice.
"Was pleased to see a £1,000 fine issued to a male who found it amusing to deliberately cough over an NHS worker at a Gwent Testing Station," Chief Superintend Hobrough said.
"Hope those who consider that acceptable behaviour think twice!
"Big thanks to NHS working at all sites. You are so appreciated by the masses."
Dan Davies is operations lead for Gwent Covid-19 testing and was among those who reported the incident at Rodney Parade on June 5.
"We must take a zero tolerance approach against the abuse of frontline public workers," he said.
"They are going above and beyond to help people. It’s beyond me why anyone would want to hurt them or cause them distress."
Gwent Police Chief Inspector Sarah Davies said she is "absolutely disgusted" by the incident.
"So glad the individual got fined," she said.
"Great decision. Let’s just hope people like this are the minority and not a reflection of the masses who fully support and applaud the with the NHS has continued to do to keep us safe."
