The US Centers for Disease Control and Prevention (CDC) has raised its Covid-19 travel advisory level for Singapore to the highest risk category at level four.
The CDC system categorises destinations by taking into account factors such as the number of recent Covid-19 cases and the trajectory of new cases.
“Because of the current situation in Singapore, even fully vaccinated travellers may be at risk for getting and spreading Covid-19 variants,” said CDC.
The agency urged travellers to Singapore to be fully vaccinated, and to abide by Singapore’s recommendations or requirements, including wearing a mask and observing safe distancing measures.
CDC’s latest warning comes as Singapore’s Vaccinated Travel Lane with the US kicks in on October 19. Fully vaccinated travellers from the US – joining travellers from 10 other countries – are able to enter Singapore without the need for quarantines.
