The US Centers for Disease Control and Prevention (CDC) on Monday urged Americans to avoid travel to Thailand, Hong Kong and New Zealand over Covid-19 cases.
The CDC raised its travel recommendation to "Level Four: Very High" for Thailand and two other destinations. In total, the CDC urges Americans to avoid travel to about 135 countries and territories.
"If you must travel to Thailand, make sure you are vaccinated and up to date with your Covid-19 vaccines before travel," it said, adding that "even if you are up to date with your Covid-19 vaccines, you may still be at risk for getting and spreading Covid-19."
The Thai Public Health Ministry reported 18,943 new Covid-19 cases and 69 more fatalities on Tuesday.
Hong Kong reported 25,150 new coronavirus infections and 280 deaths on Monday, as authorities struggle to contain a worsening Covid-19 outbreak which has torn through hundreds of nursing homes and hit many of the city's unvaccinated elderly.
While Hong Kong was successful in controlling the virus in 2021, Covid-19 infections there have recently soared to a total of around 500,000. Most of the city's more than 2,200 deaths have been in the past two weeks.
