"Crowded travel settings, like airports, may increase your risk of exposure to COVID-19, if there are other travelers with COVID-19. There are several things you should consider when deciding whether it is safe for you to travel."
Travel guidelines and alerts are usually issued for international destinations. Shortly after the coronavirus outbreak made headlines in January, the CDC issued a level 3 travel health notice, its highest, advising against non-essential travel to China, and has since raised Europe, Iran, Europe and South Korea to those levels due to coronavirus spread.
The CDC now rates the US and other most other countries a level 2 under a broad global coronoavirus travel advisory. A level 2 alert means "practice enhanced precautions.''
New United Kingdom and Ireland restrictions A British flag flies near the "Big Ben" clock tower of Parliament in London. The United Kingdom and Ireland were excluded from the Europe travel ban announced earlier this week but have been added due to a spike in cases there.
The broadened ban means residents of the U.K. and Ireland will not be allowed to travel to the United States for 30 days beginning late Monday.
U.S. residents won't be banned from flying to the United States but they will face airport screenings upon their return and will be asked to self quarantine for 14 days.
Officials said U.S. citizens in the U.K. or Ireland do not need to rush home ahead of the deadline because the ban does not apply to them.
"They will be allowed into the U.S.,'' Chad Wolf, acting secretary of the Department of Homeland Security said.
In response to the broadened ban and the resulting falloff in travel demand, airlines are likely to sharply cut flights between the U.S. and London and Ireland. Delta and American Airlines, for example, suspended all flights between the United States and the 26 European countries covered by the initial ban.
