The growing number of Covid cases in Gibraltar is a cause for concern.

The requirement to quarantine for 14 days has already been implemented for others coming from Switzerland to Scotland.
Follow a buildup of infections in the country.
The UK plans to impose quarantine situations when a country’s infection rate exceeds 20 cases, matching another 100,000 people over seven days.
Switzerland has recently exceeded this threshold, with a seven-day of 21. 2.
Quarantine regulations are established across the British country separately, however, restrictions imposed in England after the assembly of ministers will likely also be followed in Wales and Northern Ireland.
Swiss Tourism Federation Director Barbara Gisi said that with more than 1. 6 million Britons traveling to the country last year, the UK is Switzerland’s third-largest foreign market.
“Swiss tourism cannot do without long-term foreign visitors,” he said.
Speaking on BBC Radio 4’s Today programme, Gibraltar’s chief minister, Fabian Picardo, said the cases gave the impression that they were expanding in the territory, as they did more tests than elsewhere.
He said that they had “known very effectively cases of virus and exercised controls through the application of self-isolation. “
“We don’t have anyone in the hospital, we don’t have anyone in extensive care, we haven’t had anyone who died from the virus. “
He said the imposition of quarantine regulations would be “a big inconvenience” not only for tourists but also for other people traveling to Gibraltar to paint and study.
But this week a resolution will be made to replace the prestige of the island.
The Transport Ministry imposed a mandatory 14-day quarantine for some arrivals in early June.
The following month, the 4 British countries released lists of ‘travel corridors’, detailing the countries that were exempt from the rule.

Last week, quarantine restrictions were lifted for others returning from Portugal, but were added for travellers returning from Croatia, Austria and Trinidad and Tobago.
Individuals who are ingsed can be fined up to 1,000 euros in England, Wales and Northern Ireland, and EUR 480 in Scotland, and there are fines of up to 5,000 euros for repeat offenders.
