Delta travel restrictions: tourists wonder where they can go and if they should

(CNN) -- The summer 2021 travel season began full of hope and promise, but every day, two words threaten to bring it all down: delta variant.

This more transmissible variation of the new coronavirus was first detected in India in February, just as the United States and some other parts of the world were beginning to really prepare their vaccination efforts. It turned out to be a race against time: vaccines against the delta variant. And like all other waves of the pandemic, travel is feeling the impact of covid fast and hard.

From new travel advisories, issued this week, to Google searches on the subject in the last 24 hours, it's clear that the delta variant is causing increasing concern and disruption for governments and would-be travelers.

New US Travel Advisories

On Monday, the US Department of State and the Centers for Disease Control and Prevention (CDC) issued new advisories for five countries, citing rising covid-19 cases. 19:

- Cyprus (Level 4: Do Not Travel)

- Israel (Level 3: Reconsider Travel)


- Kyrgyzstan (Level 4: Do not travel)

- Portugal (Level 4: Do not travel)

- Spain (Level 4: Do not travel)

The warning not to travel to Spain is particularly significant as it is one of the most popular destinations in the world.

However, as of Tuesday, those five places were still allowing American tourists to enter if they met certain restrictions, according to State Department listings. This is happening even as the United States is dealing with its own delta variant outbreak.

Spain and Portugal join a growing list of popular travel destinations in the "Tier 4: Do Not Travel" category, which is the highest on the State Department scale. Level 4 is also the highest alert for the CDC.

Some of the other places on Level 4 as of Tuesday that are traditionally popular with travelers from around the world:

Delta variant travel restrictions: tourists wonder where and if they should go

- Argentina (which has been closed to most international tourism during the pandemic)

- Brazil (which has had a liberal policy regarding visits despite being one of the countries most affected by the pandemic)

- Maldives (These tourism-dependent Indian Ocean islands allow most visitors except for a few South Asian countries)

- The Netherlands (which opened its doors to American travelers on June 24 and welcomes most of Europe; see a full list of Netherlands "safe countries" here.)

- South Africa (many nations will not allow visitors to enter if they have recently been to South Africa)

- United Kingdom (CDC warns that even if you are fully vaccinated, you may be at risk of contracting and spreading variants of the new coronavirus)

White House: Existing restrictions will stay in place for now

More evidence of growing concern and its effect on travel:

On Monday, the White House decided to keep existing coronavirus travel restrictions in place, Press Secretary Jen Psaki said.

"We will maintain existing travel restrictions at this point for a few reasons. The more transmissible delta variant is spreading both here and around the world," Psaki told reporters. "Driven by the delta variant, cases are increasing here at home, particularly among those who are not vaccinated, and seem likely to continue for weeks to come."

The announcement came as the Biden administration has come under increasing pressure from the travel industry and US allies.

People who have been to Brazil, China, the European Schengen Area, Iran, India, Ireland, South Africa and the United Kingdom in the last 14 days are denied entry to the United States.

What people want to know: At least on Google

If you want to know what's on people's collective minds, just check Google searches. The delta variant is an upward trend.

Global searches: At around 1:30 p.m. Miami time Tuesday, Google Trends reported a 100% increase in searches for the term "delta variant travel restrictions" in the last 24 hours across the globe. world.

Other increasing searches around the world focused on restrictions for particular places: Victoria (Australia) and Mexico led the way.

The Australian state of Victoria is expected to end its fifth lockdown on Wednesday, even as it tightens the border with neighboring New South Wales, according to The Guardian newspaper. (Victoria has the city of Melbourne, while Sydney is in New South Wales.)

Australia has maintained some of the world's strictest travel restrictions since the pandemic began, only opening to New Zealand on April 19. But that "travel bubble" has been fragile and collapsed again on July 23.

Mexico, on the other hand, has had the opposite response. It has been, and continues to be, one of the easiest countries to visit.

Its land border with the United States has been closed for more than a year, but air traffic has been flowing in from all over the world. You don't even have to provide a negative PCR test result or quarantine upon arrival. Mexico was at "Tier 3: High" on the CDC's advisory list.

People around the world were also looking to the US for guidance on broader concerns with searches for "US International Restrictions." or "CDC Restrictions" which also increased in the last day.

US Searches: Search queries originating in the United States are primarily oriented abroad. Right now, very few US states have domestic travel restrictions despite the sharp rise in infections among the unvaccinated.

There was a 450% increase in searches in 24 hours for the term "Spain travel advisory", spurred by Monday's announcement. And also big spikes for more general international searches, like "Can US citizens travel to Europe?"

The answer to that second question varies by country and day, as restrictions are constantly changing. But most of Europe, including heavyweights such as France and Germany, opened to US citizens earlier this summer and remained open Tuesday even as the US travel ban continues to block many Europeans.

Searches in the United Kingdom: In the United Kingdom, the United States and Greece were the ones with the highest international interest.

For UK travelers keen to visit the US, the ban remains in place for them.

As for Greece, it was one of the first European countries to reopen. It is open to travelers from the UK and many others around the world. The countries of the EU and the Schengen Area can visit, in addition to places such as Canada, China, Japan, the United States and the United Arab Emirates.

Internally in the UK, there has been a huge increase in search interest, over 2,600%, over Scotland's plan to offer free bus travel for young people. It would be for people under 22 years of age from January 31, according to the BBC.
