UK, Grenada, Saudi Arabia: More countries open to fully vaccinated travelers

There's one menacing global traveler currently racing through countries faster than Phileas Fogg and its name is the Delta variant.

New reports suggest it's as transmissable as chickenpox but that vaccines are more than 90% effective in preventing serious disease.

So how are countries responding? Here are 10 things we learned in pandemic travel this week.

1. The US is keeping its travel restrictions...

The United States is not going to start welcoming tourists from EU member states, the UK, Ireland, China, India, South Africa, Iran and Brazil anytime soon.

A White House official told CNN on Monday that it would be maintaining existing coronavirus travel restrictions amid surging cases triggered by the Delta variant.

On the same day, the US State Department and Centers for Disease Control and Prevention (CDC) issued new advisories for five nations, citing the rise in Covid cases.

Spain, Portugal, Cyprus and Kyrgyzstan are now at Level 4 -- "Do not Travel" -- while Israel has gone to Level 3 ("Reconsider Travel").

2. ...But its mask guidance has changed

On Tuesday, the CDC ramped things up further by changing its masking recommendations to urge people in higher-risk areas -- close to two-thirds of the United States -- to resume wearing masks indoors in public areas.

Disney World, in Florida, and Disneyland, in California, are two of the big tourist attractions to have reintroduced mask-wearing indoors for everyone aged two years and upwards, regardless of vaccination status.

The Smithsonian Institution -- a huge complex of 19 museums largely concentrated in Washington, D.C. -- also reversed its mask policy on Thursday.

Meanwhile, Lollapalooza, Chicago's famed music festival, got underway on Thursday with hundreds of thousands expected to gather in Grant Park over four days of performances. Proof of full vaccination or a negative Covid test taken with 72 hours of arrival is required for entry.

3. UK cases are plummeting and no one knows why

The outlook is rosier in the UK, where reported Covid cases have dropped by 36%, just one week after England dropped nearly all of its legal coronavirus restrictions.

It might be because the European soccer championships are over, it might be because people are spending more time outside due to the warm weather, or it might be because people are reporting fewer positive Covid results because they want to avoid self-isolation -- nobody really knows why.

It's certainly good news for fully vaccinated visitors from the United States and the EU, who from August 2 will be able to enter England, Scotland and Wales without quarantining.

4. Ireland's pubs reopen at last

Indoor dining has reopened in Ireland to fully vaccinated people and those who have recovered from Covid-19 in the past six months.

Indoor hospitality has been closed for seven months -- tough going in a country known for its inclement weather -- while some "wet pubs" (those that serve alcohol but not food) have reopened for the first time since March 2020.

Close to 70% of Ireland's adult population are now fully vaccinated, according to a tweet from Stephen Donnelly, Ireland's Minister for Health.

5. Australia will enforce lockdowns until 70% of adults are fully vaccinated

Australia's largest city, Sydney, has been locked down for five weeks so far and Prime Minister Scott Morrison said in a news conference Friday that the country will continue to use lockdowns to suppress Covid-19 outbreaks until 70% of adults are fully vaccinated.

"I believe we can get there by the end of the year," he said.

International borders will begin to open after 80% of that population is fully vaccinated, with arrival caps on Australian citizens dropped and more "travel bubble" deals struck.

6. All travelers entering Grenada must now be fully vaccinated

The Caribbean island of Grenada -- also known as the "Spice Isle" -- has updated its entry requirements so that all visitors must have been fully vaccinated at least two weeks before arrival.

Grenadian citizens and children under 13 are exempt.

The island is made up of lush rainforests, spectacular waterfalls and paradise beaches -- around 45 of them, in fact. Grand Anse, a three-kilometer stretch of white sand, is the most popular.

7. Pakistan will require public workers, air crew and passengers to be fully vaccinated

Pakistan is set to demand vaccination certificates from staff entering public offices, schools, restaurants, transport and shopping malls, reports Reuters, despite only 2.7% of its population being fully vaccinated.

The new rule also applies to air passengers and crew.

Asad Umar, head of the National Command and Operations Centre (NCOC), told Reuters that certificates will be required for air travel and school staff from August 1 and for employees of malls, restaurants, public transport and public sector offices from the end of August.

8. Saudi Arabia might introduce tough measures for travel law-breakers

Saudi Arabia's state news agency SPA reported Tuesday that the country might be set to impose tough measures on citizens who break the law by visiting "red list" countries including India, South Africa and the UAE.

It cited an unnamed interior ministry official who reportedly said those who violate travel regulations "will be subject to legal accountability and heavy penalties upon their return, and will be banned from travel for three years."

It's a warmer welcome for fully vaccinated international tourists, though, who can enter Saudi Arabia from August 1, without the need to quarantine.

9. Kuwait bans unvaccinated citizens from international travel

It's getting cold out here for the unvaccinated.

Kuwait announced Tuesday that from August 1 only fully vaccinated citizens will be allowed to travel abroad, reports Reuters. Exemptions will be made for children, pregnant women and those with medical conditions.

Also on Tuesday, the country's aviation authority said that all arrivals in Kuwait must have a negative Covid test before they board their flights. They'll also have to home-quarantine for seven days until they take a Covid test inside Kuwait which comes out negative.

10. We guess this is one way to isolate within your bubble

Ray "Reza" Baluchi planned to spend three or four weeks along the Atlantic coastline "walking" from Florida to New York in a hamster wheel-like vessel he calls his bubble.

However, equipment issues with his unconventional craft forced him to abandon the effort after less than a day and he came ashore in Palm Coast, Florida, to the surprise and alarm of beachgoers.

An incident report by the Flagler County Sheriff's Office described his craft as a "metal frame with enclosed buoys, manually powered by running."
