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.   ...

The Delta variant is bringing back the sense of how important a role masks play in controlling the pandemic even as more of the population gets vaccinated. Fan filled soccer stadiums and sports activities, entertainment activities, where social distancing is not practiced, is increasing risks of spreading the virus. Mask use is seen as an essential defense in preventing spread of the coronavirus worldwide and in every country.

Tara Parker Pope of the NYT has this advice about protecting yourself against coronavirus variants after talking to many infectious disease and other experts. Don't let your guard down she says and suggests some of the same precautions that were taken in earlier waves of the coronavirus, from masks to social distancing and prudent decisions about travel and shopping.

Vaccines offer protection against common coronavirus variants such as B.1.1.7  from UK. It is still wise to follow the prudent rules that were followed before.

A look at countries in Europe shows different strategies for tackling coronavirus Delta variant as schools reopen in September 2021. Italy requires all teachers to carry a covid digital certificate that shows vaccination or PCR test results. France, Germany and Spain do not require vaccination for teachers to go to schools, and rely mostly on social distancing and mask requirements in schools. Britain not only does not require vaccination digital certificate, but also has not made masks and social distancing mandatory. Health experts say there are serious risks in this approach with mass return to schools and offices after August 2021, and the fall weather with more time indoors. This could lead to a surge in coronavirus as in the US where the reopening of schools and Delta variant has led to surge particularly in states such as Texas, Florida, California. In UK 65% of total population is now fully vaccinated, in Italy 62%. Teachers in Italy fully support the new rules. In Lombardy region with Milan as the capital, only 300 out of 300,000 workers returned to schools without the green pass, according to regional officials. Britain remains an outlier says this report in the WSJ, taking more risks than is proper at this time, and simply hoping for the best. Not the best strategy in this situation.   ...

The B.1.1.7 coronavirus variant from UK has changed the level of vaccination needed to where life returns to normal, says the Pasteur Institute in France. The level of vaccination has to be higher than the 70% or 80% earlier thought  to be needed for people over age of 18, in the range of 90% now that more infectious variant spread is happening. This also means social distancing and mask use, healthy foods and habits of exercize remain vital.

By dropping most coronavirus restrictions including masks, social distancing and size of gatherings, and opening night clubs, England is risking the same sudden rise in new cases from variants that hit the Netherlands last week. Analysis of what happened in the Netherlands shows nightclubs and bars as the origins of 40% of the new cases in the Netherlands. Prime minister Rutte of the Netherlands apologized for this kind of reopening after a big jump in cases in Netherlands.Seven day average in the UK is at 46,000 for the last week. With 40% of the UK population not fully vaccinated, the new variants can spread faster and mutate in the unvaccinated population.  There is a basic difference in priority- getting to work and doing essential shopping compared to going to nightclubs. The Dutch government shut its nightclubs after reopening them in June. At this point England is split in how to reopen. The Mayor of London says masks will be compulsory in all public transit in London. And 55% of the UK public in a recent survey from YouGov think reopening in this way is the wrong thing to do. Another poll by Ipsos shows 70% of people surveyed saying they wanted mask wearing to be compulsory indoors for another month. One bar club owner says that he thinks what they are doing is wrong. Some students think that this is a recipe for transmission to happen quickly. ...

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. ...

A chaotic return of school children to school in September 2021 in most of Europe and America, because of a lack of clear statement on the rules to be followed for mask use, social distancing, and testing. Most children are also returning to school without vaccination.  It is also happening at this time in September when the Delta variant is spreading. US president Biden's decision for vaccine mandate for 100 million or two thirds of American workers comes at this time of uncertainty in schools about the future and coronavirus variant. In the US rules are being set school district by school district, at a time when vaccines are not approved for children under 12 years. One leading school administrator in the US says "it's as chaotic as you can get."

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. ...

Senay Boztas writes from Amsterdam, Netherlands, that the strict lockdown in the Netherlands is a result of a badly handled coronavirus policy response. The Dutch experience is offered as a lesson other countries can learn from. It too long to form a government after Dutch elections in March, 271 days so that it took too long to have a policy response. When a policy response was made it faltered badly with too relaxed a lifting of restrictions without essential distancing and mask use. Restrictions at super spreader events at night clubs and stadiums were lifted all at once. The government failed to develop a policy of anticipating the next wave from variants by planning early for a booster campaign. (Israel is already into its fourth booster shot as reported in NYT).  The result is that instead of a calibrated response, because infections make up 15% of tests, Netherlands is in a sharp lockdown. A policy of prime minister Rutte that put too much into the idea of freedoms with different meanings in the west calling Holland a "slightly anarchistic country that doesn't need a preachy government," rejected vaccine mandate of any kind as in France and Austria for public transport and restaurants.   ...

This report in NYT suggests that coronavirus in New York is becoming endemic. Endemic means chronic instead of the acute crisis situation in 2020. This is because hospitalizations are not filling up ICU's the way they did in 2020. The burden of the coronavirus pandemic is now on people who are unvaccinated and people under 45 years.  New York has a higher rate of vaccination than the rest of the country. About 76% of people ages 12 and over in New York are vaccinated. Yet the 24% of younger people who remain unvaccinated is a part of the population that has fears about getting vaccinated which are harder to overcome. As many of these younger people also spend more time outdoors, and are part of the community, more likely to be in contact with families, relatives and friends indoors in winter, and less likely to wear masks and follow social distancing the pandemic, one could see another surge in the winter of 2021.  Another problem could be that some portion of the population of vaccinated has not taken booster shots by the middle of winter which would create a population of a third of the people even in cities such as New York that remain unprotected. The emergence of another difficult variant could also be a complicating factor. In this way chronic or endemic may still be elusive where masking, social distancing and other preventive actions are not taken. For the community as a whole there will be the risk to upward mobility from the people who risk losing jobs because of fears of the vaccine.     ...

The first spread event for Omicron outside of South Africa is now known to be in Norwegian capital of Oslo. Some workers of renewable energy company Scatec SA returning from South Africa where the company has a solar panel project attended an annual holiday party. The party was at Louise an upscale Oslo restaurant, with 120 people all vaccinated, and tested the day before. More than half have tested positive for covid 19, with at least 13 having the new variant Omicron. Oslo municipal health department says it expects more Omicron cases among the 64 coronavirus cases as remaining workers get tested. The results so far are anecdotal and thin to be sure, yet they show none of the infected employees were seriously ill, says this report in WSJ, citing a company spokesman. The spokesman says people had different sysmptoms but none were severe. Tine Ravlo, assistant superintendent of the Oslo municipal government says- all of them are under isolation at home. And  for now they have what they describe as mild symptoms such as headache, cough, sore throat, and flulike symptoms.  Norway has 80% of population of 5.4 million people fully vaccinated. Mask mandates are in place again in Norway, private indoor gatherings limited to fewer than 100 people. ...

The US vaccination drive appears to be stalling when it comes to getting younger people vaccinated. On a recent day 1.13 million persons were vaccinated. About 150 million Americans are fully vaccinated or about 47% of the population. About 53% of the population have one dose. This still leaves the rest of the population close to one half unvaccinated as the US is opening up fully and removing the social distancing and mask mandates that existed before. The problem is that the coronavirus delta variant is about twice as transmissible than the original coronavirus of March 2020. Vaccination is uneven across the US. Large parts of the southern states and the western states lag behind. In these areas as well as areas with large urban concentrations of population, the densely populated cities where social distancing and mask mandates are being lifted as if the coronavirus crisis is over, are at risk of seeing a more powerful virus spread quickly before gene sequencing catches up with new variants- making the response lag behind in terms of weeks. That lag in response could lead to another wave in the US. Consider also that tourism is opening up in Europe with removal of mask mandates, that gene sequencing to track variants is tiny in even countries such as Italy and France. A WSJ report on June 22 shows gene sequencing to track variants at 1% of positive tests in Italy, and virologists in Italy saying they feel as if they are flying blind. This report in the Washington Post says surveys show as many as one third of Americans have no immediate plans to get vaccinated. This is showing up in the low numbers for the vaccination drive, of around 1 million a day at this time in June 2021. In April this was 3 million vaccine doses adminstered on a single day on average. India where the new delta variant has had the most serious impact has stepped up its response with the federal government taking complete responsibility for vaccine supplies and vaccination drives. It is now vaccinating aggressively in the range of 6 million to 8 million doses a day during the last 7 days with a plan to ensure enough vaccine supplies for 1.2 billion people to get vaccinated by December 31.  The European Union and the US have  vaccinated just over 50% of their population for a variant that is more than twice as transmissible than the original virus. This leaves the unvaccinated at real risk because all the social distancing and mask mandates that existed earlier are being removed- in the US, in France, in Italy, and other countries. Soccer stadiums are filling up in Europe, the kind of sports events that later hit Bergamo, Italy, in March 2020. Summer tourism is back in Portugal and Greece. The best intentions will not be enough. Are mask and social distancing protocols being lifted too quickly especially in tourist locations reminiscent of last summer in Europe and elsewhere. Germany and Britain are holding on to them a bit longer. Will this be enough to tackle a new variant. ...
