接触感染より飛沫感染に注意を、と

緊急事態宣言の延長となりましたが、久々にCOVID-19ネタです。 接触感染よりも飛沫感染が重要ということです。 この感染症が広がり始めたころは、コロナはまず接触感染だ、だから手洗いと消毒、マスクなんてあまり意味ない、というのが世界の常識で...

COVID-19 rarely spreads through surfaces. So why are we still deep cleaning?

The coronavirus behind the pandemic can linger on doorknobs and other surfaces, but these aren’t a major source of infection.

Studies and investigations of outbreaks all point to the majority of transmissions occurring as a result of infected people spewing out large droplets and small particles called aerosols when they cough, talk or breathe. These can be directly inhaled by people close by. Surface transmission, although possible, is not thought to be a significant risk.

Hand washing is crucial, says Marr, because surface transmission can’t be ruled out. But it’s more important to improve ventilation systems or to install air purifiers than to sterilize surfaces, she says. 

Goldman continues to wear a cloth mask when he leaves home, but when it comes to the possibility of catching the coronavirus from a contaminated surface, he doesn’t take any special precautions. “One of the ways we protect ourselves is by washing our hands,” he says, “and that applies pandemic or no pandemic.”

 

 　接触感染が主で飛沫感染が福だと思っていたけど、飛沫感染が主なんだね。

　接触感染は過剰に気にするほどでもない、と。

　唄、おしゃべりなどの飛沫は要注意だね。三密ーマスクと換気、パンデミックであろうがなかろうが手洗いは大切だね。

　情報は更新していかないとね。
