Spain, Portugal, Turkey and other countries have issued their latest advice to holidaymakers.
The Foreign Office has advised British people against all non-essential travel worldwide.
This applies for an indefinite period due to unprecedented international border closures and other restrictions.
Countries across the world have also banned tourists from travelling to their country, but some have spoken out on when they believe holidaymakers will be allowed to visit.
Here's the latest advice from the Mirror Online.
Cypus – June
Cyprus has extended a ban on all inbound and outbound flights for another two weeks until May 28.
The government first imposed a flight ban on March 21 as part of a strict lockdown.
Authorities have said that airports could reopen in June – depending on the situation.
Scientists are still trying to come up with ways of safely bringing back travellers to the tourism-reliant country – which is estimated to face losing 60% of its visitors this year.
Officials have previously said, with optimism, that they may reopen their border in June.
Dubai – July
Dubai has told how it would like to start letting tourists back into the country as early as July – but has stressed this could change.
Helal Al Marri, Director-General of Dubai's Department of Tourism, said on television: "Many countries remain closed and it's more about the bilateral discussions,
"Is it going to be July when things start slowly opening up?
"Is it going to be September? We just need to make sure we're ready if things come earlier than expected."
And he expressed optimism that the industry will bounce back as it will turn its focus to "health and hygiene."
Greece – July
The country acted quickly after recording its first case of coronavirus on February 26.
And in late April, the Prime Minister Kyriakos Mitsotakis announced the plan to relax lockdown measures.
Beaches reopened on May 4 and cafes and restaurants will open on May 1 but with outdoor seating only.
But the country is grappling with what this will mean for tourists.
Mr Theoharis, who is set to hold talks with his EU counterparts, told The Guardian: "If we are to think of the possibility of travelling this year it has to be under specific new rules.
"We have to have new rules for hotels, new rules for beaches, new rules for pools, new rules for breakfast buffets, new rules for tour buses."
Italy – July
Italy was forced to impose a strict lockdown, which banned walking or exercising more than 200m away from home, after it was one of the hardest hit countries.
But now, some measures have been relaxed and people can travel for longer distances and visit some relatives.
Bars and restaurants are expect to reopen for dine-in services in June, and now the country is tentatively considering its tourism sector.
Giorgio Palmucci, president of the Italian National Tourist Board, ENIT, told local media that European tourists will be the first international group to be allowed to visit.
He said: "I am ready to sign bilateral treaties between European countries to encourage the arrival of foreigners as well, while waiting for the emergency to be definitively behind us
"We will only start (with tourists) from the European Union, and at the earliest, in July or August.
"The problem is that, unlike other sectors, tourism relies on reservations, so the window of time open for operators will be really tight."
Spain – August
Spanish residents saw one of the strictest lockdowns across Europe, with the mandatory closure of all restaurants, and adults only permitted out for essential business.
Meanwhile, children were allowed outside for an hour a day from April 26.
Adults were permitted to leave the home for exercise from Sunday, for the first time since March 15.
Speaking earlier on, the tourism minister hinted that there would not be a simple return to normal for tourists.
Spanish tourism minister Reyes Maroto told local newspaper El Pais: "We have to guarantee, when international tourism opens, that the person who comes to Spain is a safe person…
"The issue of borders will be accompanied by the evolution of the health crisis.
"Therefore, I do not have the solution of when [they will be able to open].
"On how you will be able to enjoy our beaches, we are defining different scenarios.
"It is very important that the sanitary recommendations are maintained, we are going to have to internalise what we are already doing now, hand washing, social distancing … even on the beaches.
"Those patterns will be in our day to day for a time, you cannot take a step back."
Now The Association of Hotel Chains (ACH) and the Hotel Business Federation of Majorca (FEHM) has said it is in talks with a number of international tour operators, including UK firms.
ACH president Gabriel Llobera told the Spanish press: "The objective is to be able to open the hotels in stages and whenever the demand justifies the business effort."
Turkey – August
The country had previously said that they hoped they will be able to see travellers back by July.
But whilst life for residents is slowly returning to normal as measures are relaxed during May, tourists are not yet allowed back in.
And they will need a certificate stating they don't have the virus in order to be allowed into the country, the government has said.
Turkey's Culture and Tourism Minister Mehmet Nuri Ersoy said that European tourists won't be able to enter the country until the end of July at the latest.
He added: "The tourism sector itself has a vital role in terms of returning to normal processes. The importance of caring for our guests in our culture leads us to be ready for the transition to healthy tourism before everyone.
"Our certification programme shall ensure that our guests in Turkey are going to make their holidays safely and hygienic and feel comfortable during their visit."
Portugal – 2021
The country has been praised for its swift response after going into lockdown on March 13 with just 122 recorded cases of coronavirus and no deaths.
Now travel officials have created "clean and safe" badges for companies to increase confidence amongst tourists and workers.
To be granted this seal, which will be valid for one year, firms must comply with the hygiene requirements set out by the Portuguese authorities
Other regions are expected to follow similar procedures.
But Eliderico Viegas, head of the Association of Algarve Hotels and Tourism Enterprises, said that foreign visitors are expected to start returning to the Algarve in April 2021.
He told Bloomberg in a phone interview: "This year, hotels in the Algarve will have to rely on locals for bookings, which is insufficient to keep many of these units open.
"Many hotels won't open this year."
President of the Algarve Tourism Board, João Fernandes, added: "We are committed to developing all the necessary measures, with the ultimate goal of reinforcing security and confidence in the destination."
France – 2021
Around 89 million tourists visited France in 2019 and the country has been hard hit by the loss of income.
It has left business owners fearing that tourists will not return this year at all, or only in small droves.
Chateau director Stéphanie Gombert told business mag Forbes: "At the end of May, the government will tell us when we can open again.
"We will open my business in July, perhaps 1-2 rooms at the outset.
"But I doubt for the whole year we will have any international tourists. Maybe some from Switzerland or Belgium."
