The US is to announce that Ireland and the UK will be included in its travel ban from Monday.
As it stands, any non-American citizen travelling from mainland Europe isn't being allowed in but the restrictions will widen in an effort to stop the spread of COVID-19.
Meanwhile, the Department of Foreign Affairs has advised against all non-essential travel to the Czech Republic, Cyprus, Denmark, Malta, Poland, and Slovakia.
It's due to the coronavirus measures being put in place in those countries.
Officials have already advised against all non-essential travel to Spain and no travel at all to Italy.
Additional Guidance
Tánaiste Simon Coveney today said officials will be providing "additional guidance" on Spain.
He said: "A growing number of countries are also imposing restrictions on entry and exit.
"Given the consequences for travellers, Irish citizens should exercise a high degree of caution when making travel plans particularly in Europe."
The Department's consular advice line will be open through the weekend on 01 613 1733.
Irish embassies and consulates will be using social media to keep citizens informed.
