This analysis from The Times of London provides critical information on the strategy for successfully tackling the coronavirus following the example of South Korea and progress in Britain.

The random community testing is key to getting an idea of the scale of infections in the community at large. The critical ratio called reproduction ratio tell one if the virus is under control and how lockdowns can be lifted. For Britain this 0.7 estimated by Imperial College. It has a 2 week lag. 1.0 or close to 1.0 is not good. Germany after being at about 0.7 has moved up to 1.0 with 2 week lag in information says the Robert Koch Institute. This means a lot of work ahead, it won't be easy.

South Korea has tested about 300,000 people for coronavirus. About 20,000 can be tested daily for coronavirus through 40 drive thru locations. South Korea invented this method of testing. Another feature of the South Korean method is the tracking down of people who have come into contact with those testing positive for coronavirus. The South Korean government is able to do this because it can access the credit card and cell phone information of people in the country. This is possible through laws that were passed after the failures during a previous epidemic of MERs. The government then tracks down and isolates the people who came into contact with infected persons. This includes people who show no symptoms, an important aspect of the South Korean program which needs to be adopted in other countries once the production of test kits and testing is ramped up. The reason is that about 30% of people who tested positive in South Korea were not showing any symptoms but acted as silent carriers. This is similar to the figures for people in the Wuhan region of China. This testing capability is one of South Korea's key strengths, though Germany's Robert Koch Institute says it has a similar capability to test 160,000 people a week. The U.S. has tested about 30,000 people by comparison. The U.S. government is procuring 60,000 test kits under the Defense Production Act. South Korea also enforces social distancing though a $2500 fine and a 1 year prison sentence. Germany now has a 2500 euros fine in some states for curfew violations.  By comparison the fine in Britain is insignificant.  Another difference between China and South Korea with Germany and the rest of Europe, the U.S., is that in China and South Korea self-isolation is monitored, tightening the control over coronavirus spread at every turn.   ...

Mr. Trump describes himself as a "wartime president" as he prepares to sign a Korean War era measure that allows the U.S. government to ramp up production of medical supplies.  Mr. Trump announced he was preparing to sign the 1950 Defense Production Act, which gives the president powers to direct civilian businesses to meet orders for products necessary for national security.

Mr. Trump is now holding daily news briefings on the emergency which can be seen on many television channels, including CSPAN.

In China factories producing mobil phones and other products were diverted to production of medical supplies and equipment as the coronavirus crisis escalated in February. The Chinese nation was on a war footing leading to the situation today when no new infection cases were reported. Only by doing this could 2 hospitals be built in 2 days in Wuhan to isolate patients.

The NHS Nightingale hospital was built in 9 days by converting the ExCel convention center in east London. This is the largest hospital of this kind ever built with 4000 beds. Prince Charles opening it by video link from his home in Scotland said it was " a spectacular and almost unbelievable feat of work." The hospital is named after the founder of modern nursing Florence Nightingale. The British government drafted hundreds of army engineers to help contractors build the hospital in record time. It will need 16,000 staff and hundreds of volunteers.

Prof. John Ashton, regional director of public health for the northwest of England offers this advice on pitfalls to avoid in the testing and contact tracing systems of the UK and other countries. He says there is a problem in sending testing kits through the mail or postal service. He points out that the swabs needed for testing correctly are quite invasive, the risk of an inadequate sample taken in high, resulting in a false negative report. 

On contact tracing he says the current recruiting system has pitfalls of contact tracing people not having local knowledge. Needed are people who know the local population and are able to fully engage with these people.

How is it that Britain's regulatory agency approved the Pfizer vaccine before the U.S. FDA agency? This report in the NYT says FDA looks at the raw data. Britain's Medicine and Healthcare Products Regulatory Agency looks at the information provided by the company. It still does the testing batch by batch and has access to the data and looks at thousands of pages of data. What about the European Union? The European Union Medicines Agency meets on December 29. It takes days after it meets to get input of 27 countries so that vaccination cannot start till January. The U.S. president summoned the FDA to the White House to find out how soon the FDA could act. Both Britain and the U.S. are feeling the impact of the second wave of coronavirus.

U.S. frustration with China as coronavirus toll reaches 300,000 deaths worldwide. President Trump says- "They could have stopped it in China where it came from. But it didn't happen that way. " Worst hit are countries in Asia and Africa with food security threatened. After the coronavirus he says of the trade deal he signed in January- So, I make a great trade deal and now I say this doesn't feel the same to me.The ink was barely dry, and the plague came over. And it doesn't feel the same to me." Under that trade deal the China agreed to buy $250 billion in additional goods and service for 2 years in an effort to correct a huge trade imbalance - built up on the advice of American economic theorists and experts who advised American presidents for three decades that it was of no consequence - in exchange for a roll back of American tariffs in stages of part of the tariffs.

Grim warning from chief scientific and medical advisors to the British government that we are not through this yet, there is more ahead. Without strong action there could be 200 deaths a day and 50,000 cases a day, says Sir Patrick Valance, chief scientific adviser. Tens of thousands of deaths could happen in the winter and there is little prospect that restrictions can be lifted for the next 6 months. The chief medical officer to the government says if we do too little the virus is going to take off. Sir Patrick Valance said at a joint appearance with Whitty in Downing Street that if the virus doubles in 7 days, then if we have 5000 cases a day, it would be 10,000 the next week, 20,000 the next week and 40,000 a day the week after. In a month we could be near 50,000 a day. The vaccine the advisors said may be available to small groups by the end of 2020, only in the first half of 2021 will it be a likely scenario of it being available in widespread way. On protection they say most of us are not protected only about 6-8% may be protected in the hope that immunity is gained by having been infected and developing antibodies. We have to deal with it collectively for the next 6 months as it is now growing across the whole country, not just in some places or environments. Doing too little is dangerous and could let it take off speedily and affect hospitals again, doing too much so that unemployment is affected and poverty social deprivation happens is also to be kept in mind. ...

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.   ...

During question time in the US Congress US Senator Rand Paul stated that the US money was used to fund research at the Wuhan Institute of Virology. A ban on gain of function research on virus was lifted by the US in 2018. Following the lifting of this ban which was strongly opposed by scientists at Cambridge, Massachusetts, research was conducted that many of these scientists considered dangerous and risky. This report in the BBC shows Dr. Anthony Fauci. director of the NIAID, the Institute for Allergy and Infectious Diseases responding to Dr. Rand Paul, Senator from Kentucky. Much of the discussion goes into definition of "gain of function research" and misses the broader implications. Scientists in Cambridge had warned early of the danger of doing research because of earlier mishaps such as the one involving anthrax research from accidents that are always a risk. Epidemiologist Marc Lipsitch of the Harvard Chan School of Public Health warned of just such an "accidental pandemic" in Three Questions, Three Answers in the January 2018 issue of the Harvard Chan School of Public Health journal. He stated that an "accidental pandemic" could result from the lifting of a ban on a risky kind of research favored by some virologist professionals. Most of the medical and scientific community in Cambridge fiercely opposed the lifting of the ban on what they saw as risky research with little benefit in 2018.    ...

After reading this editorial in the WSJ about the origins of the coronavirus, readers will have more questions about EcoHealth Alliance nonprofit which sent $3.4 million to the Wuhan Institute of Virology (WIV) for  research with potential for risky consequences to world public health if something went wrong.  What is gain of function research and what purpose is served in making virus more infectious and contagious such that the National Institutes of Health would send funding overseas for such research are questions that readers may have. Were all the risks considered for such research overseas. The editorial says the US Congress is not showing interest in the origins and the US president Biden has to take up this- some readers might have a question what would make the US Congress not interested in this when coronavirus has affected the US, India, Brazil, Europe, and the poorest countries on earth in unimaginable ways. Can such important matters as world public health fall under the authority of one person, such as Dr. Fauci and other health officials from one country or two countries, when other countries such as India, Brazil, UK, France, Italy, Germany, EU countries, are gravely affected. Global public health has suffered badly and billions of people around the world, in the poorest countries as well as the people in US and Europe have suffered unimaginably in 2020 and 2021 as a consequence of poor decisions. Much needs to be done to get the people themselves informed about public health and how it can be shaped in the future. ...

The British government called for 250,000 volunteers to help the National Health Service in its programs for older people. Instead it got 750,000 volunteers, in an overwhelming response. Hundreds of community based groups have also sprung up across Britain, with additional tens of thousands of volunteers seeking to help, says this report in NYT by Mark Landler. It is a massive and spirited display of national solidarity at a time of national crisis. As Queen Elizabeth II said in her television address: "Our pride in who we are is not in the past, it defines both our present and our future."

It also shows how in an affluent society one can now see the people who really matter when it comes down to this, the everyday effort to get through a day or a week at a time, says Landler. Everyone from garbage collection, grocery clerks, delivery service, and pharmacy workers, get us through each day, each week.
