Ireland has been placed at the highest risk level for travel.
The US Centers for Disease Control and Prevention has issued an advisory for Ireland, putting it in the highest risk category and advising American citizens not to travel here.
The CDC warned that even if you are fully vaccinated, there's a risk of contracting and spreading Covid-19 if travelling to Ireland.
"Fully vaccinated travelers are less likely to get and spread Covid-19. However, international travel poses additional risks, and even fully vaccinated travellers might be at increased risk for getting and possibly spreading some Covid-19 variants," the agency said.
According to CDC parameters, destinations that fall into the "very high" risk category have had more than 500 cases per 100,000 residents in the past 28 days.
1,352 new cases of Covid-19 were reported in Ireland on Monday, which was up from the 1,098 cases reported on Sunday.
Ireland is one of 16 destinations added to the CDC's Level 4 with the others being Andorra, Curaçao, Gibraltar, Greece, Guadeloupe, Iran, Isle of Man, Kazakhstan, Lesotho, Libya, Malta, Martinique, Saint Barthelemy, Saint Martin and US Virgin Islands.
Meanwhile, the US State Department also added Ireland to its Level Four: Do Not Travel advisory.
While many countries had been removed from its highest warning level since June, the US has been adding more countries back because of rising Covid-19 cases.
