The FCO has said its travel advice is constantly under review so that it reflects its latest assessment of risks to British people.
In response to coronavirus measures, the FCO is advising against all and all but essential travel to some countries, cities and regions.
The FCO warns travellers to check the travel advice to the country you are travelling to before setting off.
The FCO does not have a simple definition as to what is considered to be essential and non-essential travel.
