The variant first identified in India called the Delta variant is 60% more infectious than the Kent variant found in the UK. The Delta variant is now the dominant variant in the UK. There is concern that this could lead to another wave just as the UK is reopening in the summer. There are over 6000 daily cases in the UK this week. The estimated R number is now 1.00 to 1.2 following the number being 1.00 to 1.1 in the earlier week. A R number over 1.0 suggests greater spread of the coronavirus. An R number of 1.1 suggests the number of cumulative cases is taking off meaning that the UK is at risk of a sudden surge in the coronavirus in June or July 2021. India faced a wave from the new variant's higher rate of infectious spread. leading to a sudden surge in May 2021 to 400,000 daily cases before it was brought down by June 1 to about 100,000 The number of hospitalizations in such a wave is estimated to be higher in UK than the previous waves, requiring the government to be more vigilant today. Restrictions on travel from Portugal are being put in place in UK as a precaution. After repeated waves as a consequence of complacency with the coronavirus the lesson now is to take steps early and take aggressive action in advance. ...

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.   ...

Pakistan follows other countries by making vaccination mandatory for all public sector workers. Pakistan also requires vaccination to go to airports. France and some other countries in Europe have taken this action to prevent spread of the Delta variant.

According to the US Census Bureau 3.6 million Americans say they face eviction in 2 months as the Supreme Court voted 5-4 to end suspension of evictions July 31, 2021.

An India like surge is feared for Indonesia with the spread of the Delta variant and rising cases. Sudden spikes in Jakarta, central Java, and Bangkalan on the Java coast are straining hospitals. A nation of 270 million Indonesia has only a small vaccination program dependent on Sinovac vaccine from China, and only 5% are vaccinated.

Doctors say whether you are young or old have co-morbidities or not you can catch the coronavirus delta variant. Several members of a household can catch it and the deterioration happens quickly. Doctors in India made similar comments during the surge there in May 2021. Kudus region in central Java is typical. At first cases were declining from a January peak by May. Then cases jumped in June. A third of cases turned up positive for PCR tests.

Omicron cases are up in an almost vertical line on a graph with cases doubling every 2-3 days in the UK, similar to the pattern in South Africa during the beginning of the spread in South Africa. Since then early data in South Africa show the trend in the province of Gauteng, center of the omicron outbreak in South Africa in the Johannesburg area, has reached its peak. On Dec. 16 it recorded 27% of national infections compared to 70% the week before. Head of the National Institute of Communicable Diseases in South Africa, Michael Groome, says "we had areally dramatic increase in Gauteng, which has now leveled off."  Hospital admissions in South Africa show a different pattern than earlier hospital admission rates in previous waves, with only 1.7% of cases being hospitalized in this Omicron wave compared to 19% for the Delta variant wave at a similar point in the wave, says Health Minister Joe Phaahla. In UK as of Dec. 14, this WSJ report cites health authorites saying 73% of cases in London are omicron variant, doubling every 1-2 days, with omicron making up 41% of all cases in England. In the US the Centers for Disease Control show Omicron variant making up 2.9% of all cases in US as of Dec. 11, with highest concentration in New York, New Jersey of 13.1%. Proportion of positive tests went up from 3.3% to 5% in New York City. A convention in New York City, Anime convention at Javits Center, November 23, 2021, shown in a recent NYT report, could potentially have acted as a super spreader event in New York according to NYT though not confirmed, similar to football stadiums events in Italy in March 2020. Dense atmosphere and large crowds increase the risk of a super spreader event happening, say experts. ...

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. ...
