Gardaí have issued a warning to holidaymakers that they will face prison and a criminal record if international trips continue.
Gardaí have stated that they are waiting for several families to return from their foreign holidays before issuing court summons.
There are also plans to increase the current fine for non-essential international travel from €500 to €2,000.
Many holidaymakers were not discouraged by this fine and as a result, gardaí have warned the public to comply with the law or face prosecution in the district court.
Section 31(a) (7) Health Act 1947 gives gardaí the power to direct an individual to comply with the penal provision and that prosecution can be faced upon failure to comply.
