Prime minister Conte said in outlining the plan "if you love Italy, keep your distance." Italy has over 26,000 deaths from coronavirus. Mr. Conte said social distancing measures will be needed for months to come.

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.   ...

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 critical variable in knowing whether lockdowns of cities and countries are working is called the coronavirus RO, or reproduction ratio. This ratio measures the average number of people infected by a carrier A. It could be that he infects 1 person at work and transport call it B people , or in large gatherings call it C people he infects 2 persons, or in other surroundings such as restaurants he infects 1 person call it D people. The people A has infected B+C+D are the ones now not infected by A with the lockdowns such as in New York, Italy, Germany, UK and France. It is determined by global health experts that the number of B+C+D is about an average of 4 persons infected by 1 person A with coronavirus, though it may be much higher in practice in some areas. The natural rate of RO or reproduction ratio is considered by the European Centre for Disease Prevention and Control to be 3.86 or about 4, if no lockdown or social distancing or other prevention is practiced. This in a situation where people behaved as before unaware that the virus was around them. Governments such as New York and France, UK, Germany are including this key variable in their determination of how long a lockdown lasts, and for determining if the reopening is not going the right way or failing. In such situations the lockdown would be reinstated, or if it is a phased reopening such as in the U.S. and other countries go back to the previous phase. In Italy and Germany the RO reproduction ratio for coronavirus is estimated by official experts at 0.8. Germany's RO estimated by the Robert Koch Institute and Italy's by Franco Locatelli, scientific advisor to the government. In New York the margin is thin- with RO of 0.9, estimate from the state's governor. In France which has one of the tightest lockdowns of all with a document required to go outside it is at 0.6, the figure coming from the prime minister Mr. Philippe. In the UK it is below 1.0 but no accurate figure is reported. As Dr. Birx- leading the coordinated response in the U.S. - emphasizes over and over again this is a very contagious virus, about which not much is known. Social distancing, wearing masks, basic prevention measures such as frequent handwashing, and not gathering in large numbers of people, is essential for defeating this virus. This has to be followed up with extensive testing and contact tracing to win this fight.   ...

Italy faces tighter restrictions and a national lockdown at Easter for the coronavirus, Italians who were the first to go into lockdown on March 10, 2020, now think they will be the last to exit lockdowns. The mood in Europe is of frustration with the slow vaccination drive and the failure to procure enough vaccine supplies and to approve vaccines in time. The US and Britain have vaccination drives that are moving rapidly leading to a reduction in cases and deaths. In Europe new cases are rising since mid February 2021, and there is the spread of the new variant first detected in the UK.  The variants make up 70% of new cases in France says Health Minister Olivier Veran. ICU's in France are 80% full. Elections in France in 2022 and in Germany in September 2021 are leading to government reluctance to impose tighter restrictions. The government strategy is now being questioned. Only 30% of Germans now have confidence in chancellor Merkel's ability to make competent decisions. The CDU's partner in the government, the SDU socialists have even less trust with SDU getting less than 10%. There are signs of a third wave of coronavirus in Germany resulting from variants of the virus, slow vaccinations, and reopenings. ...

Some local governments in China are making vaccination mandatory. China is setting a goal of getting 64%  of the population fully vaccinated by the end of 2021. In European Union countries mandatory vaccination by country or region is now being put in place to fight new coronavirus variants that spread faster in the population. The reopening of economy, business and tourism is increasing the risk from variants in summer 2021. The mandatory vaccination is a way to increase the percentage of the population that is vaccinated. Getting younger people who lag behind to get vaccinated is important to protect the percentage of the elderly population that is still not vaccinated. There are risks also to the younger population as seen in previous waves of the pandemic. The initial hesitation to make health pass showing a person is vaccinated mandatory was because only a small fraction of the population was vaccinated in Europe. Now that over 50% are vaccinated in most EU countries and UK, that hesitation thinking that it is discriminatory to those people who did not have access to vaccines no longer exists. Ample vaccine supplies and the misinformation spread about vaccines are making action on health pass necessary to protect the overall population. National governments in France, Denmark, Austria, Greece, and local governments in Germany, Portugal and other EU countries such as Ireland, Italy, see the danger from coronavirus variants that spread quickly as too big to take any risks a second time. ...
