The Chief Medical Officer has dashed hopes that air travel restrictions can be eased in time for Christmas.
Dr Tony Holohan told the transport committee that as case numbers continue to decline, the risk of re-importing the virus will become more significant.
While Ireland is starting to regain control of the virus, the situation in other EU countries is worsening.
Final preparations are being made to roll out the EU traffic light system for air travel on Sunday.
Dr Holohan says he understands the impact the restrictions have on families and the aviation industry.
