WSJ was first to point out the dangers of holiday hotspots in Spain, Greece and Croatia in spreading the coronavirus in Europe. One story in the WSJ showed how 21 million tourists visiting Croatia in the summer were not following the basic social distancing and mask guidelines. These tourists returning to Germany, Austria and other countries were spreading the virus after becoming infected in bars and restaurants, shops in Croatia which had not followed the basic guidelines that had been followed earlier in Croatia in April. Over the summer after months of lockdown people simply used fatigue with restrictions as a reason for going the other way and ignoring them.

Summer tourism is helping support a second wave of the pandemic. This report says Croatia is a case study on how the opening of tourism can trigger a second wave. Because Croatia depends on tourism and Croatia had controlled coronavirus cases in May, the government decided to open its coastline areas to tourists from Europe. These tourists returned home with the infection and spread the virus. Clubs and bars were allowed to reopen for the summer season after the lockdown in April along the Adriatic coast attracting visitors. With 500 miles of coastline and Mediterranean climate, ancient towns and affordable stay, Croatia is crowded with tourists. In 2019 21 million visitors came here according to the Croatia Tourist Board. On Italian visitor from Parma cited here says she found crowded parties and bustling bars and restaurants where hardly anybody kept social distancing and wore masks. People in shops and bars she says told people they did not need to wear masks. The governments in Europe were keen on making up for the economic costs of the pandemic and opened the internal borders of the European Union in June. The opening of resorts in the sunbelt of Europe in Spain and Portugal has led to the spike in cases in Madrid and other cities in Spain. The same is happening in France. But vigilance dropped especially in Croatia where little or no restrictions were visible. Not only were bars allowed to open but the social distancing rules and mask rules were never practiced. Some Croatians call it incomprehensible. It has led to the spike in Germany, Czech Republic and Austria. The Koch Institute says 12% of all new German cases are traceable to Croatia. It is now a fact that international travel is a way the coronavirus accelerates. Governments in France, Germany, and the UK which are not especially dependent on tourism have the option to encourage people to stay in their home countries and remove this cause of acceleration while keeping shops and offices open so that business and jobs are preserved. For people hurt by lack of employment in the hospitality industry and others with lost wages from being in an occupation that acts to accelerate the virus it is a better option to offer financial assistance than to end up closing offices and shops in another partial lockdown. Opening bars helped accelerate the pandemic in California after the lockdown with steeply rising numbers of new cases. Educating the public to the extent that it should be about the dangers is also missing.    ...

European Union countries, Britain and the US face the risk of a resurgence of coronavirus through the Delta variant and other variants. The Delta variant detected in India is 40% to 80% more transmissible than the Alpha variant detected in the UK, with the Alpha variant 50% more transmissible than the original coronavirus that originated in Wuhan.    Virologists in Italy feel they are flying blind at this time because of the lack of genetic sequencing in Italy, Spain, France and across most European Union countries. The UK has done genetic sequencing on 27% of recent covid positive tests. The figure drops to 1% for Italy and is tiny for most of the EU countries including Spain and France. Without genetic sequencing it is hard to predict and take steps. Another problem in the EU is that the southern economies Spain, Portugal, Greece, Italy, Croatia are dependent on summer tourism for the economy. The UK economy can handle a delay to a full opening for 6 weeks without serious impact to the economy, says WSJ. Southern European economies can afford only short delays to full reopening. Croatia acted as a door to spread of coronavirus into central Europe when Germans and Austrians went to vacation spots in Croatia in summer 2020. This situation could be happening again in 2020 with British and other tourists visiting vacation areas in Portugal, and Germans visiting Greece and other summer tourism spots. Portugal's national health institute says the Delta variant represents 60% of new cases in the area around Lisbon based on early data. The government of Portugal is facing criticism for letting a Champions League soccer final to take place in Porto, Portugal between two English teams. Thousands of English fans watched the game at the stadium. Other problems are in relaxing of mask rules in France and Italy, last week in France and in the coming week in Italy. French nightclubs open July 9 without mask requirement. Germany is maintaining some social distancing measures and this includes mandating medical masks in closed public spaces and on public transport. Half of French, Italians, Germans are vaccinated and quarter fully vaccinated. Yet the gaps of unvaccinated people is large enough to cause serious concern of another wave. The relaxation of mask rules- the entire stadium in Budapest was packed for a recent game between Hungary and Italy for a soccer Euro 2021 game with no masks to be seen. Stadiums played a key role for the spread of the original coronavirus in Italy with a game in Bergamo, Italy, in the area near Milan. All this makes health officials concerned about the risks of still another wave of the coronavirus.   ...

How global travel and ultra cheap flights in Europe have seeded this pandemic is the subject of this report in NYT. The Austrian resort here is one of many such ski resorts. An earlier report showed how 21 million tourists visiting beach resorts in Croatia on the Adriatic are spreading the coronavirus in a second wave in Europe in September. From Europe it is a short step to the U.S. and other countries. See in Links.

Germany which handled the first wave of the coronavirus better than France or Spain with better testing and contact tracing is now facing the second wave. Following the reopening Germany went back to normal with fewer restrictions. Some Germans ignored restrictions and Germans travelled to other countries. German students in Croatia in summer tourism are reported to be part of the 21 million tourists in the country in summer that failed to follow any restrictions. The result is that Germans now fear the second wave is beginning to hit Germany.

The head of the European Centres for Disease Control ECDC, Dr. Andrea Ammon, says the Delta variant of the coronavirus will make up 70% of all cases in Europe by early August, and 90% of all cases by the end of August. ECD modeling shows that there is a risk of another wave like the one after last summer in Europe. The Delta variant is much more infectious than the UK Alpha variant and the UK variant much more infectious than the original variant. A 50% reduction in non-pharmaceutical interventions such as allowing the staging of events would lead to an increase in infection in all age groups. Latest ECDC data show 34% of people in Europe fully vaccinated and 57% with one dose. One dose offers much less protection. Younger individuals have a lower vaccination rate and are vulnerable. Also vulnerable are the older people not vaccinated yet. About 40% of people over 60 are not yet vaccinated, and 30% of people over 80 years are not yet vaccinated in the European Union. As in the US vaccination varies by region within the EU. All these vulnerable groups can be affected in another wave of the coronavirus similar to after last summer when restrictions were removed. Dr. Ammon is a former advisor to the German government. She says it is important for young people who are not vaccinated to continue to follow the strict social distancing precautions.  This is not happening today as governments are relaxing mask mandates in Britain, France and Spain. Soccer games are coming back to fan filled stadiums increasing the risk. Tourist spots in Portugal and Greece are now looking similar to the vacation spots in Croatia that increased infections in Europe after summer 2020. ...

France has made the health pass for coronavirus mandatory for leisure and cultural venues starting July 21. The health pass will be mandatory for having a coffee, eating at a restaurant, or shopping in a mall from the beginning of August. The health pass is already in use in some form in many European Union countries. Denmark and Austria are using it for 2 months. Germany and Portugal are using it regionally depending on where the epidemic is severe. Greece which has a surge of tourism in summer from other EU countries is making it mandatory starting July 16 for entry into shops and restaurants. It was the absence of  any form of constraints on behavior in places such as Croatia with high tourism in summer that increased the surge in Germany and Austria last summer. Italy and Ireland are planning to make vaccination mandatory following France as the number of cases from the variants increase. Establishments that are violators of the mandatory rule in France will be fined 45,000 euros and persons responsible having to spend 1 year in prison. The mandatory rule has significantly increased the number of people seeking vaccination in France.      ...

Lessons can be learned about careful reopening in fighting the coronavirus from other countries. Here the Netherlands experienced a rise of cases by 500% within two weeks of reopening after some poor decisions. The Mark Rutte government decided to open all bars and nightclubs resulting in a twelve fold surge in these locations in one week. Most of the new coronavirus cases were in people 18-29. Data from Dutch public health institute shows 4 out of 10 new cases linked to bars and nightclubs with 262% surge in cases for young people 18-24 years. This goes to show that with the vaccination drive what we see is the cases shifting to younger people, the unvaccinated, and to activities like nightlife. People going to work, or doing hybrid remote work with trips to the office, workers in factories, people doing essential shopping, are not causing the rise in cases. Much can be learned from these examples in working out reopening that does not lead to new crises with surging cases in new waves of coronavirus. Earlier in 2020 summer tourists who ignored mask and social distancing restrictions in Croatia brought on a post summer coronavirus wave to Germany and Austria. This time Greece and Portugal are introducing restrictions. Greece plans to make vaccine health pass required effective July 21 to go into restaurants. Another lesson from Netherlands this week is that a 20,000 person music event of 2 days in Utrecht where QR codes were required showing vaccination or PCR tests failed. About 1000 cases were attributed to the Utrecht event alone. Reasons given are that people faked the QR codes, or that the covid testing system produced too many false results as much as 20%. The same QR code system was followed at nightclubs resulting in big problems. One can never be sure that things work as expected and the risks are great as this adds up. Even vaccines offer limited protection and only if fully vaccinated depending on the type of vaccine. One dose of the vaccine is simply inadequate, and obesity, other morbidities can lead to problems. Withdrawing the mandatory use of face masks in most situations is also a risky decision of the Dutch government. Face masks offer the added protection at a time of variants that spread quckly, and when large parts of the population have only one dose of the vaccine, some elderly are still not vaccinated, and young people have not been vaccinated in large numbers. ...

How travel and tourism including tourists in Spain and Croatia and other spots seeded a second wave of the coronavirus in Europe, and how this poses risks for the U.S. with increased travel. A new variant of the original virus is spreading in Europe and could be spreading in the U.S.
