Both the Swedish Social Insurance Agency and the Swedish Work Environment Authority have this year received thousands of reports of illnesses and work-related injuries linked to the corona pandemic.
But the number of police reports of suspected work environment crimes has thus been significantly lower.
According to the Public Prosecutor's Office's national unit for environmental and work environment cases, so far only nine reports have been handled.
- It has become much fewer than we thought it would be, says chief prosecutor Kristina Falk Strand to SVT.
Of the nine reports, three have been written off directly, while in six cases preliminary investigations have been initiated.
But so far, half of these have been discontinued.
The latest example concerns the high-profile case in which a nurse at Karolinska University Hospital, who herself cared for covid patients, died of the disease.
The investigation was closed on December 1 because covid-19 did not prove to be the main cause of death, and because it was not possible to show where the nurse was infected or that there were no deficiencies in the hospital's procedures.
Reported by private person
Kristina Falk Strand says that the difficulty is often just to prove the connection between the disease and the workplace.
Today, therefore, only three preliminary investigations are underway into suspected work environment crimes related to covid-19.
The latest was started in the autumn and concerns a nursing home in Skåne, which was reported by a private person who states that staff went between covid departments and regular departments.
The prosecutor in charge tells SVT that the investigation is at a very early stage.
Another investigation that is still ongoing concerns the special accommodation Berga in Solna, which was examined in several reports by SVT Stockholm.
Even in that case, there has been information that staff have gone between sick and healthy - something that has been rejected by the company that owns the accommodation.
