EU Commission Recommendation (EU) 2022/2337 recommends that Member States list COVID-19 as an occupational disease.
In Ireland, the Department of Social Protection is responsible for maintaining the list of prescribed occupational diseases and for giving consideration to the inclusion of particular conditions. This is laid down in S.I. No. 102/2007 - Social Welfare (Consolidated Occupational Injuries) Regulations 2007.
Given that this question specifically relates to considerations as to whether COVID-19 should be included in that list, my department is not in a position to provide a response.
It would therefore be a matter for the Department of Social Protection who has responsibility for the legislation setting out the list of prescribed occupational diseases.
