The Foreign and Commonwealth Office (FCO) has advised against all but essential travel to 35 countries.
Coronavirus has been reported in 144 countries, territories or regions.
The World Health Organisation (WHO) has declared Covid-19 a pandemic.
The FCO has now issued updated travel advice warning people against visiting certain countries or areas.
The advice ranges from avoiding an entire country to recommending travellers seek advice before travelling.
The current FCO advice is:
China
The FCO advises against all travel to Hubei province due to the outbreak, and against all but essential travel to the rest of mainland China.
If you are in China and able to leave, the FCO says you should do so.
United States
On March 14, the US government extended an existing European travel ban to the UK and Ireland, with the exception of returning US citizens and legal residents.
The FCO subsequently updated its advice on March 15 and advises against all but essential travel to the whole country.
The update was a way for the British government to officially inform its citizens about the extension of the ban and advise that they should not travel.
Italy
The FCO advises against all but essential travel to all of Italy, including Sicily and Sardinia.
Authorities in Italy have advised against travel for tourism purposes and said tourists already on holiday in Italy should limit their movements to those necessary to return to the place where they live.
Spain
The FCO updated its advice on Spain in the early hours of March 15, advising against all but essential travel to the whole country.
Previously, the Spanish ministry of health declared the areas of Madrid and La Rioja, and the municipalities of La Bastida and Vitoria, and Miranda de Ebro, as places where there is community transmission of coronavirus and the FCO advised against all but essential travel to those regions.
Denmark
British nationals are advised against all but essential travel to the whole country, after Danish authorities announced they would be closing the borders for a month in response to the pandemic.
Foreign nationals who “do not have a recognised purpose for entering Denmark” will be barred from entry.
Norway
The department advises against all but essential travel to Norway, after the Norwegian authorities said that all non-resident visitors arriving from countries other than Finland and Sweden would be asked to leave Norway on arrival.
British nationals legally resident in Norway will be allowed to enter the country but must enter self-quarantine for 14 days.
Indonesia
The FCO advises against all travel to two parts of the country close to Mount Agung and Mount Sinabung craters due to ongoing volcanic activity.
The department advises against all but essential travel to the rest of the country due to a 14-day quarantine requirement.
Poland
The FCO advises against all but essential travel to the country, owing to restrictions being put in place following the outbreak, which has seen borders closed and border controls introduced.
Non-Polish nationals will only be able to enter the country if they are a spouse or child of a Polish national, hold a Pole’s Card, or otherwise have the right to stay or work in the country.
British nationals aged 70 and over and those with pre-existing health conditions are advised against cruise ship travel.
Kenya
The FCO advises against all but essential travel to Kenya after authorities there announced measures restricting people, other than Kenyan citizens and resident permit holders, from going if they have travelled through countries affected by coronavirus, including the UK.
The restrictions will come into effect from Tuesday.
Cyprus
The FCO has advised against all but essential travel to Cyprus. They have advised people to follow the advice of the Cypriot authorities, including leaving their tourist accommodation by March 21. All hotels and tourist accommodation have been instructed to close by Saturday until April 30.
A state of emergency was declared in the country on Sunday.
South Africa
The FCO advises against all but essential travel to South Africa following restrictions announced limiting who can enter the country.
Authorities said travellers from high-risk countries, including the UK and US, would not be permitted to enter the country from March 18.
Visitors from high-risk countries, including the UK, who have entered the country since mid-February will be required to present themselves for testing.
The FCO also advises against all but essential travel to Argentina, Albania, Burma, Czech Republic, Dominican Republic, Ecuador, Equatorial Guinea, Estonia, Guatemala, Honduras, Jamaica, Kosovo, Latvia, Liberia, Lithuania, Malawi, Malta, Morocco, Mongolia, Paraguay, Peru, Philippines, San Marino, Sierra Leone, Slovakia, Sri Lanka, and Vietnam.
The department cites partial or complete border closures due to Covid-19 as the reason for the warnings for Albania, Ecuador, Equatorial Guinea, Guatemala, Honduras, Jamaica, Kosovo, Latvia, Lithuania, San Marino, Slovakia, and Sri Lanka.
Potential issues with flights due to restrictions and cancellations are referenced in the advice for Argentina, Morocco, Mongolia, Paraguay, Peru and Philippines.
The risk of being placed into a quarantine is given as the reason for the advice for Burma, Estonia, Indonesia, Liberia, Malawi, Malta, Sierra Leone and Vietnam.
Travellers are advised against all but essential travel to parts of Portugal and South Korea.
The FCO advises against all but essential travel to the Portuguese archipelagos of Madeira and the Azores and the South Korean cities of Daegu, Cheongdo and Gyeongsan which have been designated “special care zones” by authorities due to outbreaks.
