The US Department of State has confirmed it will launch a review of its current travel advisories this week.
It said this would likely result in a "significant increase" in the number of countries on its "do not travel" list
Updated advisories will "better reflect" the US Centers for Disease Control and Prevention’s (CDC) science-based travel notices, said the department.
These take into account issues affecting travellers’ health, as well as logistical factors such as in-destination testing availability and any current travel restrictions unique to US citizens.
