EVERYONE in Wales with symptoms of coronavirus will be able to request a test as a new online booking service becomes available.

From today, Monday May 18, Wales is joining a new UK-wide system for ordering home testing kits, in line with the Welsh Government’s Test Trace Protect strategy.

The four UK Chief Medical Officers confirmed the loss or change in smell or taste (anosmia) has been added to the list of symptoms of coronavirus.

This means from May 18, people will need to self-isolate if they have a loss or changed sense of normal smell or taste. They will also be able to request a test using the new system.

All members of their household must also self-isolate for 14 days, unless the person with symptoms has a negative test result.

Anyone experiencing the other coronavirus symptoms – a high temperature and continuous cough – will also be able to apply for a home testing kit using the new UK online portal. For further information and a link to the booking website, visit https://gov.wales/apply-coronavirus-test

I have been watching some videos by Doctor John Campbell, which I found interesting and informative, please judge for yourself.


I would like to think this is just not wishful thinking............

Good News, Reinfection Unlikely...............   https://www.youtube.com/watch?v=uATMbGK__Tg&t=7s


Quote from the the Wall Street Journal  Updated May 19, 2020 6:40 am ET.........  SEOUL—South Korean health officials found that a group of patients who tested positive a second time for the coronavirus hadn’t passed the disease on to others, lending credence to the possibility the suspected relapses were a testing fluke rather than the re-emergence of an active infection.

I wondered about that; with almost every virus I can think of once you've had the illness and survived, you're normally immune.

Dr John Campbell again discussing ....  Scientific evidence for mask wearing.......... again please judge for yourself.

"The study, conducted by a team of scientists in Hong Kong, found the rate of non-contact transmission through respiratory droplets or airborne particles dropped by as much as 75 percent when masks were used.

“The findings implied to the world and the public is that the effectiveness of mask-wearing against the coronavirus pandemic is huge,” said Dr. Yuen Kwok-yung, a leading microbiologist from Hong Kong University who helped discover the SARS virus back in 2003."

A Fox news report on the same experiment
The study, described as a first of its kind, placed hamsters in two cages, with one of the groups infected with COVID-19 and the other being healthy. They placed the animals in three different scenarios to analyze the effectiveness of the face coverings.

In one scenario the mask barriers were placed only on cages with the infected subjects, another saw the masks covering the healthy subjects, and the third saw with no mask barriers at all. For all of the scenarios, a fan was placed between the cages to allow for the transmission of respiratory droplets.

They found that when the mask was placed over the infected cage the infection rate dropped to just over 15 percent.

That infection rate went up to 33 percent when the mask barrier was only used to cover the healthy hamsters’ cage.

With no mask barriers at all, roughly two-thirds of the healthy hamsters were infected with the virus within a week, the study found.

Researchers added that the hamsters who were infected even with the mask barrier had less of the virus in their bodies when compared to those infected without the masks.

From NS:

"More than 200 schools which had reopened in South Korea on Wednesday were forced to close again today due to a new outbreak of coronavirus. The country reported 79 new cases on Thursday, the highest number in two months.

A few big names being called into question in these difficult times, names we should be able to trust....The World Health Organisation now the Lancet..........

The Guardian article ..........The Lancet is one of the oldest and most respected medical journals in the world. Recently, they published an article on Covid patients receiving hydroxychloroquine with a dire conclusion: the drug increases heartbeat irregularities and decreases hospital survival rates. This result was treated as authoritative, and major drug trials were immediately halted – because why treat anyone with an unsafe drug?

Now, that Lancet study has been retracted, withdrawn from the literature entirely, at the request of three of its authors who “can no longer vouch for the veracity of the primary data sources”. Given the seriousness of the topic and the consequences of the paper, this is one of the most consequential retractions in modern history.

It is natural to ask how this is possible. How did a paper of such consequence get discarded like a used tissue by some of its authors only days after publication? If the authors don’t trust it now, how did it get published in the first place?

The answer is quite simple. It happened because peer review, the formal process of reviewing scientific work before it is accepted for publication, is not designed to detect anomalous data. It makes no difference if the anomalies are due to inaccuracies, miscalculations, or outright fraud. This is not what peer review is for. While it is the internationally recognised badge of “settled science”, its value is far more complicated.

Full article  https://www.theguardian.com/commentisfree/2020/jun/05/lancet-had-to-do-one-of-the-biggest-retractions-in-modern-history-how-could-this-happen#maincontent

The Lancet article ......After publication of our Lancet Article,1 several concerns were raised with respect to the veracity of the data and analyses conducted by Surgisphere Corporation and its founder and our co-author, Sapan Desai, in our publication. We launched an independent third-party peer review of Surgisphere with the consent of Sapan Desai to evaluate the origination of the database elements, to confirm the completeness of the database, and to replicate the analyses presented in the paper.

People in Wales recommended to wear three-layer face coverings in certain circumstances

“Further scientific evidence is needed on the benefits to the wider public of wearing face coverings, but observational findings so far suggest that homemade or purchased three-layer face-coverings might reduce transmission from one person to another if made, worn, handled and disposed of properly.

“Therefore, on balance, we are recommending to the people of Wales that three-layer face-coverings should be used in situations where social distancing measures can be more difficult to achieve, for example, on public transport. We are not recommending their use outdoors.

“The wearing of face coverings will not be mandatory, but we will encourage people to do this for the benefit of themselves and others.”

I recommend reading this article in full, very informative on the subject of Vit D and the reduction of inflammation in the chest, if taken sensibly.


Last comment in the article......
"evidence that low vitamin D levels can hamper the immune system. Vitamin D helps reduce inflammation and can stimulate the release of antimicrobial proteins that kill viruses and bacteria. "

A few months ago I decided to start taking Vit D, so did a lot of people, I waited over 5 weeks for delivery, so seems popular ?

New York Times article......
Exploring the Links Between Coronavirus and Vitamin D
Sales of vitamin D to promote immune health have soared, but studies of vitamin D and Covid-19 have yielded mixed results.

“I think when you’re sitting in Europe, you feel like you just had the epidemic and everyone’s coming out of it. It feels like it’s over with. But it’s actually just at the start in every country in some ways,” says Azra Ghani at Imperial College London of covid-19’s spread.

Her view is backed up by World Health Organization statistics, which show that the world experienced its highest daily jump in new confirmed coronavirus cases on 7 June, a record that has since been broken three more times. “Although the situation in Europe is improving, globally it is worsening,” said WHO general secretary Tedros Adhanom Ghebreyesus at a press conference on 8 June.

The virus’s spread continues as the world rapidly approaches the grim threshold of half a million confirmed deaths, with 433,000 reported as of 15 June. The milestone of 8 million confirmed cases will probably be passed in the next 24 hours.

The geographical burden of covid-19 is shifting. While the US is still worst affected, with more than 2 million cases and more than 100,000 deaths, it is now followed by Brazil, Russia and India, followed mostly by European countries. Peru has the eighth most cases, and the WHO has called South America the new epicentre of the epidemic. The Middle East’s share of global new cases has climbed too in the past fortnight. Cases in Africa are still relatively low, but are speeding up: reaching 100,000 took 98 days, but 200,000 just 18 days.

Worldwide, the average number of daily new confirmed cases in June has settled at a higher level than in May. However, David Heymann at the London School of Hygiene and Tropical Medicine says deaths, rather than cases, are the gold standard for measuring transmission, despite reflecting events around two to four weeks ago. Unlike cases, global daily deaths are relatively static, averaging 4295 in June so far, versus 4619 in May."

Coronavirus: How does the UK's death toll compare with other countries?

The UK currently has the third highest number of recorded coronavirus deaths in the world. Only the United States and Brazil have had more, and both countries have far bigger populations.

But while the UK has been hit hard, how does it really rank alongside other countries?

Just comparing Covid-19 deaths doesn't give the full picture as countries have different ways of recording deaths. Scientists and ministers say it's better to look at total deaths, even the ones that aren't caused by coronavirus.

So what can we learn about the UK's toll if we look at it this way?

'Coronavirus deaths' can miss many of the victims

We're slowly seeing good news merging.  People with type A blood have a 45% higher chance of catching a serious form of Covid than average, and folk with type O have a 35% lower chance.

Coronavirus experts on latest 'R number' estimate - and why it could become less reliable

The way the transmission of coronavirus is measured in Wales may soon have to change if case numbers continue to drop.

Experts from the Technical Advisory Cell, which advises the Welsh Government on the coronavirus outbreak, said that if positive cases continued to fall, the R number would become less reliable.

The number is used as a measure of how infectious the disease is, and gives an estimate of how many people an individual carrying the virus is likely to go on to infect.

A North Wales consultant leading trials looking for existing drugs to fight Covid-19 says seeing people rushing to shops as lockdown is relaxed “terrifies” him.

Dr Chris Subbe is consultant in acute respiratory and intensive care at Ysbyty Gwynedd, a senior clinical lecturer at Bangor University and has numerous research paper credits to his name.

He spoke to the Local Democracy Reporting Service about his team’s work trialling dexamethasone and his fears about what he called “the most deadly infection we have seen in Europe in my professional lifetime”.

He said he was concerned to see people rushing to reopened stores and gathering in groups.
