in the air "several minutes" and spread across two aisles of a supermarket.Scientists created a computer simulation to study how far the virus can travel indoors - and worryingly found how a cloud of droplets will infect others even after the sick person has walked away.

Professor Ville Vuorinen of Aalto University in Finland told the BBC: "If you go there, only go there seldom as possible. Stay there as short a time as possible"In astatementaccompanying the video, the researchers said: "Preliminary results indicate that aerosol particles carrying the virus can remain in the air longer than was originally thought, so it is important to avoid busy public indoor spaces.
"This also reduces the risk of droplet infection, which remains the main path of transmission for coronavirus."The study was conducted by scientists from Finland's Aalto University, the Finnish Meteorological Institute, the VTT Technical Research Centre of Finland, and the University of Finland.
Experts researched how small airborne aerosol particles are transported in the air when emitted from the respiratory tract when sneezing, coughing or even talking.They said: "In the situation under investigation, the aerosol cloud spreads outside the immediate vicinity of the coughing person and dilutes in the process.
"However, this can take up to several minutes.“Extremely small particles of this size do not sink on the floor, but instead, move along in the air currents or remain floating in the same place."The simulation shows how the particles can stay in the air for 'several minutes' after a cough

Despite the growing evidence that people could have the virus and not show symptoms, the UK and the WHO do not think it is a necessity for people to wear face masks.In theUKit is advised that only health workers and carers that should wear the protective face masks.
Health Secretary Matt Hancock said the Government's health advisers had not told him to change the UK’s approach to members of the public wearing face masks.He said there was little evidence to show the masks help and would be better used by healthcare workers and patients who test positive.
But it puts the UK at odds with the increasing number of countries starting to advise their citizens to wear some form of face-covering when they head outdoors.In the US the Centers for Disease Control and Prevention (CDC) recently recommended wearing a cloth face-covering in public where other social distancing measures are difficult to maintain.
These include pharmacies and grocery stores.In Morocco, there is a government order to wear masks followed by threats of fines and imprisonment.Give now to The Sun's NHS appealBRITAIN’s four million NHS staff are on the frontline in the battle against coronavirus.

A terrible newspaper. This gives me an idea. If there was only a way to introduce a bright color to corona virus as it’s forming ,like splicing it into it’s DNA. Then we’d see where it travels both in the body and in the atmosphere. tell joggers to stop spitting - that should be a fine Would speeding the airflow through supermarkets help ?
Fart in the biscuit isle similar And here’s where u end up in 1 of these Sunderland hospital This proves to me that wearing masks IS useful. If you cough behind the mask you don't get the cloud. Why do the WHO and so many governments advise against wearing them? Can someone explain that to me, please But you're all ok being 2metres apart from eachother
Where’s page 3 this is terrible. The use of masks is mandatory in grocery stores. But how much can it prevent?
