Management Information: Coronavirus (COVID-19) disease reports made by employers to HSE and Local Authorities since 10 April 2020

Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR), certain cases of COVID-19 in workers where there is reasonable evidence to suggest that it was caused by occupational exposure are reportable to the relevant enforcing authority.

On 1 April 2022, revised guidance on RIDDOR reporting requirements for COVID-19 was issued. Since 1 April 2022 only cases of COVID-19 due to either deliberately working with the virus (such as in a laboratory) or being incidentally exposed to the virus from working in environments where people are known to have COVID-19 (for example in health and social care) are reportable. Cases due to general transmission (either worker-to-worker, or from contact with members of the public) are no longer reportable. [See note 2 below].

Given this change in reporting requirements, the number of reports made from April 2022 onwards is not directly comparable with earlier time periods.

Latest published figures show a decrease in the number of RIDDOR disease notifications of COVID-19 in workers where occupational exposure is suspected (294 notifications in May compared with 738 in April (see also notes 1- 4 below).

Of the 1,032 notifications of COVID-19 in workers reported under RIDDOR since 1 April 2022:

For more details, see the table in the link below.


  1. Data on number of COVID-19 RIDDOR reports made by duty holders is available from 10 April 2020. This is the date the statutory disease reporting form was changed to enable systematic identification of COVID-19 reports.  (Guidance was also issued on this date around reporting requirements for COVID-19 deaths under RIDDOR).
  2. On 1 April 2022, further guidance was issued on reporting requirements for COVID-19 to bring such reporting back in line with HSE’s core role of regulating businesses to ensure workers and members of the public are protected from the harm created by work activities. From 1 April 2022, cases of COVID-19 due to general transmission in the workplace (either worker-to-worker or from contact with members of the public) are no longer reportable. Full details on reporting requirements post April 2022 can be found on our guide RIDDOR reporting of COVID-19.
  3. Data is as reported by employers. While individual cases are reviewed by the relevant enforcing authority, these counts do not reflect the outcome of these reviews.  It should also be noted that as the data is ‘as-reported’ by employers there is potential for some error in some of the reported data items.
  4. This data is intended to provide an indicator of the numbers being reported to the enforcing authorities and how this changes over time rather than an accurate count of the absolute number of occupational COVID-19 cases. It should be noted that many of the reports made reflect historic cases, sometimes from up to several months ago.

Advance notice: Next planned update

These numbers will next be updated at 10.00am on Monday 11 July.
