Infected Tube passenger showers coronavirus droplets over another person simply by TALKING to them in shocking simulation


 

People talking on the tube can literally cover other passengers with coronavirus

Researchers say talking can spread small droplets of breath short distances

They say wearing a face mask can stop this from happening and slow the spread 

Here’s how to help people impacted by Covid-19

대화만으로 코로나바이러스 감염되는 경로, 시뮬레이션으로 입증


    코로나 바이러스에 감염된 사람은 지하철이나 작은 사무실과 같은 폐쇄적인 환경에서 누군가와 대화하는 것만으로도 그것을 감염시킬 수 있다는 것이 시뮬레이션결과 밝혀졌다.




소프트웨어 회사 MSC가 제작한 튜브 여행 시뮬레이션에서 한 명의 감염자가 말 그대로 다른 승객에게 COVID-19를 감염시킨 것을 볼 수 있다.


연구원들은 TV에서 친구와 대화하는 누군가가 치명적인 코로나 바이러스에 감염될 수 있다는 것을 발견다 - 비록 그들이 재채기나 기침을 하지 않더라도


숨에서 나오는 물방울이 밀폐된 공간에 퍼지는 방법을 살펴보는 새로운 모델은 영국이 직장, 학교, 그리고 폐쇄 이후 정상수준으로 복귀할 준비를 하는 가운데 나왔다.


레스터 대학의 호흡기 질환 전문가인 줄리안 탕 박사는 BBC 뉴스에 "말함으로써 생기는 물방울은 재채기나 기침에서 나오는 것만큼 멀리 이동하지 않는다"며 "그러나 연구자들은 그것이 바이러스를 옮길 만큼 충분히 위험하다고 말한다"고 말했다.


'그들은 여러분의 맞은편에 앉아 있는 여러분의 친구나 여러분에게 수다를 떨고 있는 누군가에게 영향을 줄 정도로 충분히 멀리 여행할 수 있다'라고 그는 말했다




'동료에게 손을 대지 않고 침을 뱉지 않을 때, 대부분의 상호작용은 목소리와 호흡에 의해 이루어진다.'


표면을 통해 전달될 수 있는 코로나 바이러스의 경우, 이것은 런던 지하철 여행객들에게 더 큰 문제를 야기합니다. 왜냐하면 대화에서 나오는 물방울들이 다른 승객들뿐만 아니라 좌석, 단추, 손잡이에도 있기 때문이다.

A person infected with coronavirus can pass it on just by talking to someone in a closed environment such as a tube train or small office, simulations reveal.


In a simulation of Tube travel, produced by software firm MSC, one infected person can be seen literally coating other passengers with COVID-19 - just by talking. 


Researchers found that someone chatting to a friend on the tube can 'coat others' with the deadly coronavirus - even if they don't sneeze or cough. 




The new model looking at ways droplets from breath spread in enclosed spaces comes as Britain prepares to return to work, school and a level of normality after lockdown. 




Public transport has become busier as people return to work and children prepare to return to school. Researchers say talking without a mask can spread the virus


Dr Julian Tang, an expert in respiratory conditions, from the University of Leicester, told BBC News that droplets produced by talking don't travel as far as they do from a sneeze or a cough - which can travel up to 22ft - but researchers say it is still dangerous enough to pass on the virus. 


'But they can travel far enough to affect your friend sitting opposite you, or someone who's chatting to you,' he said.


'When you're talking to a colleague you don't touch them, you don't spit on them, most of the interaction is by voice and breathing.'

In the case of coronavirus, which can be passed on through surface transmission, this causes a bigger problem for London Underground travellers - as the droplets from conversations won't just sit on other passengers - but also on seats, buttons and handles.   


MSC Software, who created the Tube simulation, says wearing a mask is essential for slowing the spread of the deadly virus.


They found many droplets are expelled from the mouth and nose within a minute of someone talking and they proceed to coat others nearby.  


This can be mitigated by wearing a face mask, which blocks the majority of front facing droplets as people talk, breathe and even cough or sneeze, say researchers.
