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. ...

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. ...

This report in FR24 says the UK reopening by June 21 is at risk as the new delta variant is leading to a rise in covid cases. Covid is growing at 3% a day, with the R ratio at between 1.0 and 1.2 for the second week in a row, says the UK Health Ministry. With new more contagious variants what looks cautiously optimistic in one week can look very different in a 2-3 week period after that especially as complacency creeps in and essential protocols are neglected.

The problem facing Africa is whether vaccine supplies will run out before new vaccine supplies come from America, Britain and France. Only less than 1% of African people have been fully vaccinated out of a population of 1.3 billion people. US president Biden said America will provide 500 million doses of Pfizer vaccine to poor nations before the G-7 meeting in Cornwall, UK. Britain added 100 million and France 30 million doses. With new more transmissable variants out there Africa is in considerable danger today. The Delta variant from India has been shown to be about 70% more contagious than the Alpha variant from Kent UK. It is already the dominant variant for new cases in the UK. The new variants are now spreading in Africa. Cities such as Johannesburg, South Africa, and Kampala, Uganda are seeing a surge in cases. Another problem in Africa is that governments are increasingly reluctant to impose strong lockdowns because of the economy. Already it is believed that Africa's middle class has been severely affected during the last 18 months. ...

Protection from hospitalization for Omicron variants can drop to 57% from 81% after 6 months from second dose, and can be pushed back up to 90% using booster shots for Pfizer and Moderna vaccines, according to a large CDC study in the US. For Delta variant period last year the vaccine effectiveness against hospitalization was 90% from about two weeks after dose two till 6 months, dropping to 81% after 6 months, and up to 94% after a booster shot. For Omicron variant the currently vaccine effectiveness for same periods is 81%, 57%, and 90%.

With vaccine hesitancy in the US the goal of vaccinating a large part of the US population is still elusive. Less than half of the US population is fully vaccinated as of July 30. The vaccination rates in the US are now much slower than India even taking into account the population difference. The vaccination in India is at the rate of 4 to 5 million a day for the past week in India. In the US this report in The Guardian shows 4.7 million vaccinated in the past 2 weeks. On July 30 856,000 people were vaccinated in the US compared to over 5 million in India.  Newspaper reporting that encourages vaccine hesitancy people to delay getting vaccinated because of poorly reported headlines is adding to vaccine hesitancy in the US. This has led to much frustration at the White House. The threat of the Delta variant is making more people to take vaccination. Southern states are seeing a jump in vaccinations. Many prominent Republicans are now endorsing vaccination.  One of the problems in tackling the Delta variant is the confusing nature of the CDC guidance on masks. On May 13 CDC issued guidance saying masks were not necessary indoors and outdoors. Now 3 months later in July the CDC says the threat of Delta variant means mask wearing is essential particularly indoors because of the higher transmissibility of the delta variant.  ...

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 third or booster dose of vaccine is needed to take out the Omicron variant. The UK Health Security Agency analyzed data from 581 Omicron cases and thousands of Delta cases to calculate how effective vaccines such as Pfizer and Astra Zeneca were against the Omicron variant. This early analysis shows a third booster dose prevents around 75% of people from getting any coronavirus symptoms. The double dose of the vaccine however provides good protection against severe coronavirus that needed hospital treatment says the UK Health Security Agency. Of equal concern is the rate of spread of the Omicron variant. Here this BBC report shows graphs of UK National Health Security Agency which show the rate of spread is rapid with cases doubling every 2-3 days. For the UK which on December 10 had about 1265 cases this means says this BBC report that the number of Omicron cases could be well above 100,000 in the UK by the end of December. The BBC graph shows the curve for Omicron cases moving in a close to vertical direction upwards. Reports say the experience in South Africa where the Omicron variant was first detected is similar in pattern causing rapid spread. ...

China faces risk of a surge inthe coronavirus in June 2021. The area in and around Guangzhou appears to be seriously affected. The city tested almost its entire population of 18.7 million between June 6 Sunday and June 8 Tuesday. This report shows pictures of a deserted Beijing airport, strict restrictions on foreign travel. The SinoPharm vaccine effectiveness against the Delta variant in India and UK is unknown. The government is locking down entire neighborhoods rather than entire cities or provinces.  As the risks of the Delta variant and other new variants increases most of the population even in the US and Europe have either no dose or one dose. Researchers at the University of New South Wales in Australia show the Astra Zeneca vaccine effectiveness with one dose at only 30%, only after two weeks following the second dose does the vaccine effectiveness reach about 70%. The population of China and India are so large that much larger parts of the population remain unvaccinated. In China with 1.3 billion people and even if the figure of 800 million doses stated by the government is accepted- it could be an overestimate as the US has only managed 300 million doses with many vaccines- most of the population is unprotected. Vaccine skepticism is high in China making vaccination an uphill task. SinoPharmvaccine is not as effective as Pfizer, Moderna, Astra Zeneca, or Covaxin vaccines, making the task even more of an uphill kind. ...

Risks are increasing in the southeast and midwestern states in the US where vaccination rates are as low as 30%. The Delta variant of coronavirus is now the dominant virus strain in the US. It is highly transmissible, estimated to be about 50% more transmissible than the original virus. The region covering Missouri, Iowa, Kansas and Nebraska, as well as Wyoming is affected, in addition to the southeastern states, as these states have lower rates of vaccination and vaccine skepticism. As communities in the US and UK reduce pandemic restrictions and open for the summer the risks of last year are being brought up by experts.

Already vaccination experts at the Baylor College of Medicine cited here say they foresee another wave of the coronavirus in the Southern US because of vaccine skepticism barriers to vaccination, and much of the population not being vaccinated. The percentage of the population in the Carolinas, Georgia, Georgia and Louisiana, that has both doses of vaccine is low. About 50% have had just one dose. In southern states Mississippi and Alabama the vaccination rates are much lower leaving large parts of the population unvaccinated. The widespread presence of the Delta variant in the UK and the R rate being between 1.00 and 1.2 in UK shows that the UK even with higher vaccination rates than the US is still facing a danger of another wave as it reopens.  The ominous aspect of this is that from just over 400,000 the vaccinations per day dropped to 316,000i n the US. This means there will be a period when vaccination drive is stalled while the reopening is fully underway with a new contagious variant twice as contagious as the original coronavirus. This leaves the US at risk of another wave, with the south and western US, younger people who are out more and unvaccinated, more at risk.  ...

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 US has a history of vaccination mandates, going back to the Revolutionary War under George Washington when all soldiers in 1777 were required to be vaccinated and Boston required the population to be vaccinated in 1809 for smallpox. Vaccine mandates were adopted during the measles, and diphtheria vaccination campaigns, and for other diseases. It is only through the mandates that these diseases were controlled. The coronavirus is no different as states and cities across the US take up mandated vaccination to avoid taking any risks with the fast spreading Delta variant.

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.

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.

After stalling in summer 2021 US vaccination picks up in August to 865,000 on August 4, 2021. At one point vaccinations reached 3 million a day and stalled with younger people hesitating to get vaccinated. Some southern states Tennessee, Oklahoma and Georgia see a surge in vaccinations. This happens as US daily cases exceed 100,000 for the first time on August 4. Of this 50% are in 8 southern states including Florida, Texas, and Louisiana. Florida is the worst affected state. Hospitals are again being overwhelmed with new cases of delta variant among the unvaccinated in August. Southern states have lagged behind in vaccination.

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.

So far Covax Africa is proving to be a failure. Consider the numbers 1 billion people only 31 million vaccines given. Another wave of the virus is underway with 130% rise in cases in Uganda, increase taking place in DRC, Namibia. About 30% increase in cases for all of Africa this week. The new Delta variant that is twice as contagious as the original virus is widespread in the UK and is an unacceptable risk in Africa and in Europe and the US.


 By comparison India has 1.2 billion people and 230 million people vaccinated with at least one dose.

The Biden vaccination target of 70% of American adults at least partially vaccinated with one dose by July 4, 2021 remains elusive as vaccination rates have dropped. From a high of 2 million a day vaccinations have dropped to 400,000 a day during the first week of June 2021. Vaccination skepticism particularly in the south and western part of the US is making it harder to vaccinate the rest of the US population. This poses increasing risks as the new variants of the virus such as the Delta variant found in India, and now the most widely prevalent strain of virus in the UK, remain a serious problem. The unvaccinated population in the US is too large for any degree of safety in numbers vaccinated. Consider that at the press briefing given by the White House on June 3, 2021, only 28 states out of 51 states have fully vaccinated 50% or more of their population. There is a large variation between different states with states in the south such as Mississippi as low as 34% at least one dose and a similar situation in Alabama. In Arkansas, Georgia, Carolinas, and Louisiana  it is higher at about 50% with at least one dose. Even these figures are deceiving as in some parishes in Louisiana only 20% have even one dose. Studies show that only after the second dose are enough antibodies released to protect well against coronavirus. This is why vaccine experts at Baylor College of Medicine cited in NYT foresee a second wave in the southern US because of the South so underachieving in the case of vaccination.  ...
