変異株に対する警戒が強まっている 米国で2変種株検出

海外情報では、当然ながら、PCR検査のプライマー設計を工夫してウイルスゲノムの複数箇所からのPCR産物シグナルを比較する事で、従来株と変異株の種類を同定できるPCRシステム確立している筈。実際に最初に英国で見つかった理由は幸運にもそう設計されてた。PCRで迅速発見したのち詳細ゲノム解析の筈。

Another coronavirus variant linked to growing share of cases, several large outbreaks, in California
Health officials stress they haven’t determined whether the variant might be more contagious or resistant to vaccines
A coronavirus variant first identified in Denmark has ripped through Northern California − including outbreaks at nursing homes, jails and a hospital in the San Jose area − prompting state and local officials to investigate whether it may be more transmissible.
California officials disclosed the rise of the variant Sunday night after genetic monitoring linked it to a fast-growing share of new cases, as well as to the outbreaks in Santa Clara county, which includes San Jose.
This rising variant is distinct from the highly contagious mutation discovered by Britain, which has also been found in California, and which federal health officials project could become the dominant strain in the United States by March based on its proven higher transmissibility.
Experts stress that they need to look more closely at the circumstances of the Northern California outbreaks, as well as at the latest variant − this one, known as L452R − before declaring it more contagious or more dangerous than the virus already broadly circulating.
The L452R variant was first detected in northern Europe in March and has since been confirmed in more than a dozen states, including California in May. The discovery did not garner much attention at the time because all viruses change constantly as they replicate. But public health authorities deem some variants to be “of concern” if evidence suggests they might be more contagious, potentially deadlier or resistant to vaccines.

ティア3ロックダウン中だった英国の経緯を考えると、半月から一月で本邦には蔓延する恐れがありますね。
本邦では全くでの打ちようがないのでもうなるようにしかならないでしょう。

[ロンドン 14日 ロイター] - シャップス英運輸相は14日、ブラジルで確認された新型コロナウイルス変異種を巡る懸念を理由に、南米諸国およびポルトガルからの入国を禁止すると発表した。
対象国はアルゼンチン、ブラジル、ボリビア、カーボベルデ、チリ、コロンビア、エクアドル、フランス領ギアナ、ガイアナ、パナマ、パラグアイ、ペルー、スリナム、ウルグアイ、ベネズエラ、ポルトガル。15日0400GMT(日本時間午後1時00分)から実施される。
ポルトガルに関しては、ブラジルとの往来が多いためとしたが、ポルトガルから必需品を輸送する労働者に関しては入国を認めるとした。
また、英国とアイルランドの国民や居住権を有する人には適用されないが、10日間の自主隔離が求められるという。新コロナウィルスの変異株に対する疫学者の警戒が強まっています。

British coronavirus strain confirmed in Russia in late 2020
Now the patient is no longer contagious, Anna Popova, chief of Russia’s sanitary watchdog, said
MOSCOW, January 10. /TASS/. The first case of the British coronavirus strain was confirmed in Russia at the end of 2020 and now the patient is no longer contagious, Anna Popova, chief of Russia’s sanitary watchdog, said on Sunday.

"By the end of the last year, we saw that we had a variant of the British strain that is provoking serious fears now. It was found in only one person who felt and is now feeling well. He had no symptoms. Now, he is not contagious," she said in an interview with the Vesti news roundup on the Rossiya-1 television channel.

Thirty-two out of more than 7,000 people who arrived from the United Kingdom in a period from late November to the day when air service between the two countries was suspended tested positive for the novel coronavirus infection, Popova, said.

"More than 7,000 people had arrived in Russia from the United Kingdom from late November to December 22 when air service [with the United Kingdom] was suspended. Thirty-two of them were found to have the virus upon the arrival," she said.

According to Popova, twenty-eight of these thirty-two people had no symptoms. "Two of the remaining four people had mild forms [of the disease], and two needed hospitalization. But we have spotted all of them and took samples from them," she said.

The British strain of the novel coronavirus can be identified by PCR test used in Russia and the anti-coronavirus vaccines registered in Russia can ensure protection against it, Popova said.

"According to our data, testing systems used in Russia for PCR diagnosis detect this virus. And the vaccines that have been registered in Russia 100-percent ensure protection against it," she said.

She noted that the virus has not become more dangerous and doesn’t cause more serious forms of the disease but it has become more infectious. "It means that one person can infect more people," she said.

The United Kingdom’s Secretary of State for Health and Social Care, Matt Hancock, said on December 14, 2020 that British scientists had identified a new coronavirus strain that might be to blame for high infection rates in southeastern England. Hancock said preliminary analysis indicated that the newly-discovered virus strain was spreading faster than any of those exposed previously. Prime Minister Boris Johnson told an urgent news conference on December 19 that according to the current findings the new strain might be 70% more contagious. He added that British experts had not yet found any proof that the virus mutation was fraught with a greater risk of lethal outcome.

Following this news, Russia suspended air service with the United Kingdom from December 22.

Ohio researchers say they’ve identified two new Covid strains likely originating in the U.S.
Key Points
Ohio researchers said Wednesday that they’ve discovered two new variants of the coronavirus, one of which has become the dominant strain in Columbus, Ohio.
The new strain prevalent in the city appears to spread more easily, the researchers said.
“This new Columbus strain has the same genetic backbone as earlier cases we’ve studied, but these three mutations represent a significant evolution,” Dr. Dan Jones, lead author of the study, said.

日本人は、学歴偏重ですが、学者の助言を生かそうとする機運は薄い。確かに人格、識見が疑われる学者も多い。

福島原発事故以降、それをいやというほど見せつけられました。新コロナウィルスでも日本の疫学者のレベルの低さ、人間性の未熟さに、うんざりしています。

能力、識見の低い学者を重用する政府は、国民はそれを歓迎していると思っているのでは?

Why Was It So Hard to Raise the Alarm on the Coronavirus?
By David Wallace-Wells


4) Excerpt... from this piece
https://nymag.com/intelligencer/

5) I’m sometimes too sad to think about the alternate universe... in which we listened to science. So many #COVID19 deaths, hospitalizations, and #LongCovid could’ve been prevented.
科学に耳を傾けた違う宇宙について考えると時に悲しくなります。 非常に多くの#COVID19の死亡、入院、および#LongCovidを防ぐことができたはずです。
This Coronavirus ‘Alarmist’ Looks Pretty Good Right Now

6) Some people ask why did I put my science career on the line by shouting at the rooftops. Well, I consider my living on borrowed time. We all die someday−I am merely living because I survived a baseball sized tumor when I was young that took out my lung and other organs parts.
なぜ私が科学者としてのキャリアを賭けてまで 屋上で叫んだのかと聞く人もいます まあ、私は自分の生活は借りた時間だと思っています。我々は皆いつかは死にます。私が生きているのは、若い頃に野球ボールのような大きさの腫瘍で肺や他の臓器を摘出して生き延びたからに過ぎません。
7) so as William Wallace says in Braveheart... “every man dies, but not every man really lives”. And because I got a second free chance at life, I wanted to help the world... so I became an epidemiologist... short story below

8) P.s. I still have the majority of my lungs

. Just lost part of ones, and lost another few organ pieces here and there. I’m okay now.

But COVID LUNG damage is real... take it seriously please...
しかし、COVIDLUNGの被害は本物です...真剣に受け止めてください。
