England's travel quarantine rules DID work

England’s original travel quarantine measures which forced arrivals to stay inside for 14 days did reduce the spread of Covid, scientists say.

Cambridge University experts tracked more than 4,000 infections linked to foreign travel from May to September 2020, to assess the first few months of No10’s rules.

Ministers made all arrivals self-isolate for a fortnight. Exemptions were only available for certain people, such as those arriving from destinations where a ‘travel corridor’ was in place. 

But the list was repeatedly amended, with favourite holiday hotspots such as Spain, France, Portugal and Italy added and removed. 

Researchers compared the number of contacts the cases reported over the two days before they developed Covid symptoms.

Arrivals from countries with quarantine requirements had 3.5 contacts, on average. For comparison, the figure stood at 5.9 for people returning from countries in No10’s ‘travel corridor’. 

Scientists said this was proof the measures — once blasted as ‘completely useless’ — worked by limiting the number of people bringing in the virus from overseas. 

It was particularly effective among 16 to 20-year-olds, who tend to have much higher contacts than other age groups.

And they said travel quarantine had the added bonus of discouraging people from going abroad, limiting the risk of the virus re-entering the country.

Dr Dinesh Aggarwal and colleagues did not look at restrictions on arrivals over the last year, which saw the Government introduce green, amber and red lists and hotel quarantine.

The study, based on contact-tracing data from NHS Test and Trace, also didn’t look at travel bans imposed on South Africa when Omicron emerged.

South Africa called the bans a ‘travel apartheid’, accusing the UK and other nations of ‘punishing’ it over the mutant strain.

Timeline of Covid travel restrictions in England

17 March 2020: Britons advised against ‘all non-essential travel’.

8 June 2020: 14-day quarantine periods imposed for travellers arriving from abroad.

10 July 2020: Travel corridors opened, permitting people arriving from certain countries not to self-isolate. 

The list was prone to last minute changes, often throwing people’s summer plans into jeopardy.

14 December 2020: Self-isolation periods shortened to ten days. 

15 January 2021: People are required to show a negative Covid test result upon arriving in the UK. 

18 January 2021: England suspends all ‘travel corridors’ to stop new variants entering the country. It comes after many European countries banned UK visitors due to the new variant.  

15 February 2021: Hotel quarantine opens for arrivals from ‘high-risk’ countries. People will be required to stay in the Government-managed centres for ten days at a cost of £1,750 per adult.

17 May 2021: Holiday ban ends, and the ‘travel corridors’ system is replaced by a new ‘traffic light’ system. 

It is also plagued by last minute changes to the rules, discouraging international travel. 

19 July 2021: Quarantine requirements lifted for double-jabbed travellers returning from amber list countries, opening up tourism again. 

26 November 2021: South Africa becomes the first country to be put back on the red list amid the spread of the Omicron variant. It is quickly joined by other countries.

15 December 2021: All countries are again removed from the red list after Omicron becomes established in the UK.

But British ministers defended the move as ‘decisive’, saying they were ‘waiting to see’ exactly how dangerous Omicron was. 

Currently, double-vaccinated travellers are only required to complete a passenger locator form when arriving in England.

But this could be scrapped before the Easter school holidays. 

Unvaccinated travellers are asked to get a test before and after they arrive in the country, although they are no longer required to self-isolate.

Dr Aggarwal, an infectious disease expert, said: ‘Our study shows that while travel restrictions are effective in reducing the number of imported Covid cases, they do not eliminate them entirely.

‘It’s likely that one of the main reasons that quarantine measures helped is that they put people off travelling during this period.’

In the study — published in Nature Communications — researchers used data to find Covid cases linked to travel and the number of contacts each reported. 

Contacts were people who had face-to-face contact with an infected individual for more than 15 minutes, possibly through sitting next to them in a car or plane.

It was not possible to determine how many of these later developed Covid because of the way data was recorded.

Almost half of Covid cases in the study were from countries under 14-day quarantine rules.

But the top sources of infections were all on the ‘travel corridor’ list allowing arrivals to dodge the rule. 

Greece was the single-biggest source of cases from abroad over this period (21 per cent of the total). 

It was not removed from the travel corridor until early November.

Croatia (16 per cent) and Spain (14 per cent) were also major sources of imported cases and both off the list. 

Broken down by age, quarantine measures had the greatest impact on 16 to 20-year-olds. Their contacts fell from 9 to 4.7.

There was also a big impact among 21 to 25-year-olds, who saw contacts drop from 6.5 to 3.5, and 26 to 30-year-olds, where they fell from 4.8 to 2.4. 

The scientists wrote: ‘For most common destinations, barring Spain, imported cases appear to reduce after the closing of a travel corridor and subsequent requirement to quarantine.’
