京都府立医科大学の研究チームは、 新型コロナウイルスが、インフルエンザウイルスに比べて ヒトの皮膚上で長期間生存することを明らかにしたと発表しました。 こちらは ヒトの皮膚表面でのウイルス量が時間とともにどう変化するかを示したグラフで、 赤が新型コロナウイルスを、青がインフルエンザＡ型ウイルスを表しています。 研究チームによりますと、 新型コロナウイルスは皮膚上で９時間程度生存することが明らかになり、 これはインフルエンザウイルスよりもおよそ５倍長いということです。 京都府立医科大・廣瀬亮平助教 「ウイルスが付いているものを手で触って、 その後喉や口や目の辺を触ると、それによって感染するので、 手の上で長生きをするということは、 そういう機会が増えてしまうということでいくと、 感染リスクが上がると考えたほうがいいのではないかと思っている。」 一方、研究チームは、 濃度８０％のエタノールによる消毒効果についても評価を行いました。 それによれば、15秒間の消毒でウイルスが完全に不活化され、 「新型コロナウイルスに対する手指消毒の重要性を実証した」 としています。 京都府立医科大・廣瀬亮平助教 「エタノール消毒薬を使用すれば、 （ウイルスが皮膚上で）長生きするとはいえ、 過度に心配する必要はないのではないかと思っている。 ただ、長い時間生存するということは、裏を返すと、 やはり感染のきっかけが把握しづらい。 例えば手に１時間しか付いていないということであれば、 感染のきっかけ、他者に移すきっかけとかも認識できる可能性があるが、 やはり７，８，９時間と長い時間手に感染性のウイルスが残っていて、 どこを触ったかもわからないとか、どこからもらったかわからないという 状態になってしまう可能性がある。 最近、感染した人への風当たりが厳しい部分もあるが、 接触感染という観点から行くと、 なかなか個人の努力だけでは厳しいかなというところがあるので、 そこに関しては周りの方も優しい目で見てほしいと思う。」

The research team at Kyoto Prefectural University of Medicine discovered that the new coronavirus, compared to influenza virus, survives for a longer time on human skin.
This is (graph shown on the screenshot) a graph showing how the amount of virus that is viral on the human skin surface changes over time. Red represents the new coronavirus and blue represents influenza A virus. According to the research team, it was revealed that the new coronavirus survives on the skin for about 9 hours. This is about five times longer than the influenza A virus.
Assistant Professor Ryohei Hirose, Kyoto Prefectural University of Medicine stated
"By touching something with a virus with your hand, then touching your throat, mouth, or eyes, you will be infected by it. The evidence that the virus lives long on your hands means the higher you will be exposed to the virus and thus I think it's better to think that the risk of infection will increase. "
Meanwhile, the research team also evaluated the disinfecting effect of ethanol with a concentration of 80%. According to the research, the virus was completely inactivated by disinfecting with the 80% ethanol for 15 seconds and it "demonstrated the importance of hand sanitizer for the new coronavirus".
Assistant Professor Ryohei Hirose, Kyoto Prefectural University of Medicine stated "If you use an ethanol disinfectant, Although the virus lives longer (on the skin), I don't think we need to worry too much. However, the fact that the virus survives longer means it is hard to figure out how an individual got infected. For example, if you the virus was on your hand for only an hour, It may be possible to track down the cause of infection and the cause of transfer to another person, but the infectious virus can remain on the hand for 7, 8 and 9 hours, and it is hard to tell what you touched that had the virus and where you got the virus from. Recently, there are negative views on people how got the virus, but looking from the point of view of infection via contact, it is difficult for an individual to put in the effort only, and I would like people to be more kind to them.”
