　どうもブラジル変異株P1というのが面倒らしく。

BBC Covid Brazil variant 'may spread more easily' 2 Mar 2021 By Michelle Roberts

　UKに、石油関連会社の労働者経由で数例入り込んだというが、言われてみればそりゃあそうだという問題点が。

「The Brazil coronavirus variant now found in the UK appears more contagious and may evade immunity provided by past infection, scientists say.」

　―そもそもブラジルはノーガード戦法で先進的で、積極的に死者を出して集団免疫をつける方向だったはず。でもなんで最近、やたら死んでるの―？という疑問は持って然るべきだ。

「The preliminary work puts the chance of reinfection at between 25% and 60%.」

「Lots of people were infected with the original version of the virus at that time, with blood test results suggesting as many as three-quarters of the population getting some degree of protection or immunity from this exposure.

Despite this, people in Manaus were hit badly by another wave of coronavirus in the winter.」

　…どうも先行するオリジナル株より感染力が高く、死亡率もまあまああるようで―そのせいでブラジルはいまのざまになっているようで―。

BBC Covid-19: Mystery UK person with Brazil variant found 5 Mar 2021

「A mystery person in the UK infected with the Covid variant of concern first found in Brazil has now been traced.

Last week, it was announced that six cases of the P.1 variant had been found in the UK - but the identity of one of the cases was unknown.」

「Scientists say the variant appears to be more contagious and there are concerns vaccines may not be as effective against it.」

「The three cases in Scotland were all oil workers who were returning to their families from Brazil, via Paris and London. 」

「Preliminary data from Manaus - the Brazilian city hit hard by this P.1 variant - suggested the variant could be up to twice as transmissible as earlier Covid.」

　…英国としては、ワクチンはしないよりしといたほうが良さそうだ、できるだけ頑張って新規株にも対応できるようにしよう！という方向の様子。
　まあ、ブラジルでと同じようにはなかなかなりがたいだろうとはいえ。警戒は重々すべきでしょうよね。
