More than 800 police officers have tested positive for Covid-19 across the country.
Since the pandemic began 849 officers have had a positive test.
Those figures come from the 24 of the UK's 45 police forces who responded to Freedom of Information requests, meaning the total is likely much higher.
According to the Police Federation officers are in "constant worry" when confronting offenders who might spit, bite or cough at them.
The figures include 228 officers from Police Scotland, 101 from West Midlands Police and 95 from Greater Manchester Police.

At Merseyside Police, where Chief Constable Andy Cooke tested positive in March, 62 officers have contracted the virus.
The figures do not include the Metropolitan Police, which is yet to respond to the FOI request submitted in September.
Forces that responded did so between October 6 and November 6, so case numbers could now be higher.
In August, the National Police Chiefs' Council and College of Policing issued new guidance to forces on the use of personal protective equipment.
Advice was also given on social distancing and enhanced hygiene measures, but it was accepted that maintaining a two-metre distance was not always possible.
John Apter, chairman of the Police Federation, said it was "inevitable" some officers would catch the virus given the nature of their work.
He added: "As well as the danger of contracting the virus, policing the pandemic is also taking a toll on the mental health and wellbeing of officers as they continue to work 12-hour shifts and have rest days cancelled to help protect the public at this difficult time.
"There is also the constant worry of bringing the virus home to their loved ones, which is exacerbated when they deal with offenders who weaponise the virus by spitting, biting and coughing - which is disgusting and unacceptable.
"People need to realise that behind the uniform, officers are mothers, fathers, sons and daughters."
Mr Apter urged the public "not to give up now" on suppressing the virus and to follow latest guidelines to reduce its spread.
The National Police Chiefs' Council also urged the public to follow regulations.
Chairman Martin Hewitt said: "Whilst demand levels remain high we are well-prepared to respond to any crime or other issues that arise."

Other forces have not come back with a response or refused to answer on grounds such as the protection of personal identities and intention to publish the information at a future date.
