Vietnam has an excellent record in the coronavirus epidemic with zero deaths and 324 cases. No locally originated cases are seen. The country has an astounding 792 tests per confirmed case compared to 144 for Taiwan and 57 for South Korea. Vietnam acted quickly to close its borders, quarantine foreign travelers in camps, close schools, and imposed an early lockdown.  This gives Vietnam an opportunity to restart its economy and maintain its growth. With the reallocation of supply chains away from China underway, Vietnam sets an ambitious growth rate of 5% for 2020, down only slightly from 7% for 2019.  The coronavirus also had some positive effects including the digital transformation that is taking place-  the rate of online transactions in public services increased from 12% to 24% during the 2 month lockdown. The discipline showed in Vietnam for tackling the crisis contrasts with other countries in Europe and America. This report says some small businesses and export industries in clothing and shoes are affected, yet even a 3% growth rate in 2020 makes Vietnam a winner, as the future in 2021 looks good. ...

The opening of bars and restaurants risks restarting the coronavirus epidemic in South Korea again after a 29 year old man visited 5 clubs and later tested positive. Contact tracing identified the man but similar cases in the Itaewon neighborhood have led to the conclusion that about one third of 5000 people believed to be involved in bars have not been traced. Over 50 cases have been traced to this one person alone. 

It is now believed that the entire South Korean efort could unravel with the mistakes of a few people. Now president Moon says "its not over till its over," and that it will be a long time before the coronavirus is ended completely. He warned a new wave of infections could happen anytime anywhere.

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.

The coronavirus surge in southern states in the U.S. is different from the surge earlier in the northeast including New York and New Jersey. More young people are getting the virus. About half of those testing positive are now 18-35 years of age in Texas and Florida. Social distancing and masks is not mandatory with young people not practicing these safety guidelines. Many took the reopening to mean they could go back to the usual summer routines. Not taking it seriously is leading to more infections of young people. Cultural issues with practicing the guidelines and a tendency to not take it seriously has been a problem in the U.S. and parts of Europe since the beginning of the crisis leading to larger number of cases.

With coronavirus spread out over wide parts of each country and with so many people infected it is very difficult to do the contact tracing and isolation that was tried during the first wave. In Germany during the first wave efforts for contact tracing and isolation worked reasonably well. During the second wave in November things have changed. In Germany authorites do not know in November where 75% of the people testing positive for coronavirus got it. In Spain this figure is 93% for the last week of October. In France and Italy it is at 80%. In New York it is over 50%. Other problems are the increasing number of cases where the coronavirus is spread in an home setting, the lack of restaurant data collected on who visits, and the delay in getting test results. In Germany frequently people say they cannot remember where they were. Researchers from the German version of the FBI, the Pasteur Institute in France and the Koch Institute in Germany are getting involved in November to understand in what settings the virus spreads most. ...

This WSJ report on critical analysis of coronavirus data has a very useful chart of Estimated Range of Symptomatic Cases Reported by Country. Complete coronavirus data for all symptomatic persons who have the coronavirus infection is lacking in most countries. Many people in large populations have symptoms and are positive but are not reflected in the official data collection. This is a big problem as the total number of cases are understated by a magnitude of twice to five times the numbers reported in official tally.   South Korea has done a good job of getting more of the symptomatic people with the infection in its data, as about 53% to 90% of such persons are reflected in official data. Next comes Germany at a range of 38% to 55%.  China comes third and has about 28% to about 38% of such persons reflected in its data, the U.S. currently on April 4 at about 14% to 19%, according to this chart in the WSJ. The source for this is Mathematical Modeling Center at the London School of Hygiene and Tropical Medicine. What this means is that the US. number of cases at 278,000  reported infected people with symptoms (April 4) is only 14% to 19% of the true number. Another way to say this is that the actual infected persons with symptoms is about 5 times what is reported, or over 1 million not the 278,000 reported.  As happens for China data collection agencies may never get the true number. To be comparable to the Chinese numbers, as the U.S. is a large country, the figure closer to the true numbers would be twice the 278,000 reported or over half a million symptomatic infections of coronavirus in the U.S. Why is this data important. With widespread testing as in South Korea one gets data that tells one how many people are infected (the size of the problem) and therefore the resources needed and the point of greatest impact. Also it tells one the typical transmission rate per person, and it helps hospitals in each area know what to expect and what resources are needed to prepare- not find people suddenly turn up in the E.R. in unpredictable numbers. The lack of widespread testing and better reporting in the data to get a grip on the pandemic is shown in this chart for countries hardest hit, less than 5-6% for Italy and Spain. The UK and France at 5-8%.   ...

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. ...

People in California did not feel the early blows of the coronavirus like New York. This is now turning into a disadvantage as people in California have now failed to follow the guidelines for social distancing and masks as carefully as they should be. The state reopening  took place as the case numbers were increasing as the economy and unemployment became an issue.  State hospitalizations are up 40% on July 1 from 2 weeks ago. Percentage of tests coming positive are close to 6% but in some counties much higher- in Riverside county has rate positive in tests at 11.7% and bars are only recommended to close. In Los Angeles county it is 8.2%. On June 20 the day after the bars were allowed to open 500,000 people visited bars in Los Angeles County. A big problem is that for lockdown the whole state was asked to lockdown by the governor. For reopening it is done by county and each county is doing this differently. Pressure to reopen has led to counties with increasing and poor metrics for cases still reopening. Some counties felt pressured to open when other counties had reopened. Even when a county such as Riverside or Los Angeles county is doing poorly the governor waits 14 days for it to be on a watch list before acting. This is too long for the extremely contagious virus giving it time to spread quickly. Governor Newson is now facing serious problems tackling the coronavirus. ...

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.   ...

About half of UK adults reported experiencing high levels of anxiety says the Office of National Statistics for the the first lockdown. During the second lockdown the fatigue coming from that period in March and the higher level of cases is likely to have increased the number of adults experiencing anxiety. Anxiety was experienced from the loneliness and the effect of the coronavirus on work. A quarter of all adults reported increased sleeplessness. Stockpiling, overworking, irritability, micro-managing, and alcohol consumption, are some of the erratic responses to this level of added anxiety. Experts suggest different responses. leadership and incremental change to put the problem into context. Such as in the case of coronavirus the important behaviours that one can control such as masking properly, social distancing properly, ventilating and cleaning the air with aircleaners, using necessary caution in outside exposure by limiting to the essential, and taking nutrients for defence against virus, other actions. After putting these in place the risks can be minimized.  At that point focusing on the present is seen by experts as the right way to respond. Get through this period or this week first, leave the next week or the next period for next time. To do this  baking, reading, hobbies, running, walking, yoga, gardening, and outdoors, a whole range of other activities including watching sports, listening to radio and music, all fall into this. Spending time doing things that make us happy. A good exercise is asking how does this make me feel, am I more relaxed? am I happier? Put things in perspective, is this catastrophising? Is this making it bigger than it is? Can I put away the illusion of control when control requires some higher power such as God. Can I leave that part to God, to the divine. Cognitive behavioural thinking modification is a way of tackling stress, loneliness, and the depression and anixety that feed on each other. Being aware that we may have wrong behavioural responses, asking questions about how accurate our thinking about things that pose threatening situations is, are helpful in tackling the anxiety.   Just breaking the pattern of behavioural responses of repetitive thinking is helpful by engaging in other activities. Meditation is helpful. Yoga is helpful. In this pandemic learning about nutrition and increasing one's knowledge of food, eating and exercizing right, of cooking, is a useful way of turning a negative into a positive.     ...

The new low cost Abbott test is about the size of a credit card and can be adminstered in a doctor's or school nurse's office. Test results are given in 15 minutes. Abbott says 97% of positive cases are detected. Plans are to increase production to 50 million in October from tens of millions shipped in September. It sees this test as the kind of test that can help schools and offices reopen. It is called the Binax Ag Card. 

It searches for virus proteins and is intended for use within 7 days of coronavirus symptoms. It involves a nasal swab given by a health care worker or nurse.
