Dr. Ronan Glynn:

When the expert advisory travel group meets on a given date, it looks at Ireland's 14-day incidence and then it is advised that every country with a case rate of more than 500 per 100,000 will be included, regardless of Ireland's position. Then if a country has a case rate of less than 500 per 100,000 but more than 2.5 times Ireland's current 14-day incidence, the advice to date has been that this country would also be considered for inclusion.
