Horrific video shows runners breath can spread ‘cloud of coronavirus over 2m’ – The Sun
THIS horrifying video reveals how coronavirus particles from a runner can infect you even if you're two metres away from them.
Currently, Brits are allowed to go for one run a day during coronavirus lockdown – as long as they stick to the strict social distancing measures.

However, a shocking new animation has proven that the UK's two metre – or six feet – social distancing rule might not be enough to keep you safe during the pandemic if you're out jogging.
Tech company Ansys created a video which reveals you could come into contact with droplets of Covid-19 even if you stay six feet behind another person while you are walking, running or cycling.
The experts say that because of this running side-by-side could be less risky than in single file, as you are far less likely to be struck with any potentially infected fluids.
Health chiefs have emphasised the importance of social distance during the coronavirus outbreak as being the key to curbing the spread of the potentially life-threatening virus.
It comes as the number of cases of Covid-19 in the UK continues to rise every day – with the current total standing at 60,733 and the death toll now at 7,097.
Marc Horner, the principal engineer for healthcare at Ansys, emphasised the danger of spreading coronavirus while out running.
He told the MailOnline that the simulation gives you "that mental image in your mind of how far away you need to stand so gravity has time to pull the droplets down."
If an infected individual coughs or sneezes, moisture is said to be unlikely to travel further than six feet or two metres – hence the official guidance.
The video shows two scenarios: one in which two people are running side-by-side and another in which they are running in single file behind the other.

In the side-by-side scenario, when one person coughs or sneezes, the majority of the droplets travel behind the runners, not next to them.
Mr Horner added that this is what makes the scenario in which runners jog in single file so unsafe.
He said: "If someone coughs, those droplets are suspended in the air and, if you are six feet behind, you are going to run right into them and it doesn't give them enough time to fall to the ground.
"The droplets go straight out and go behind you so if you're next to someone – ignoring wind conditions – it won't hit you."

Aside from running next to each other, which may prove unsafe on a road or a narrow towpath, joggers could run in a staggered formation.
Horner says this will help prevent cough or sneeze droplets from landing directly on you.
The video follows recent reports that find that two metres may not be enough to be protected from Covid-19.
According to Wired.com, infected moisture droplets will travel further than two metres when expelled with extreme force or when carried by the wind.
Scientists believe that under normal circumstances, the average person will infect 2.5 other people every five days.
When this ratio is continued for a month, 400 people will become infected.
However, the infection rate can be reduced if contacted with other people is avoided.
If the infection ratio were to be halved to 1:1.25 every five days then each infected person would be responsible for just 15 infections each month, rather than 400, and the spread of the virus will slow.
How long social distancing should be practised depends on a number of factors.
The Deputy Chief Medical Officer of England, Jenny Harries, says some form of social distancing is likely to be required for up to six months, with lockdown for up to three of those months.
She commented:“To make it clear to the public, if we are successful we will have squashed the top of that curve [of infections] which is brilliant.
“But we must not then revert to our normal way of living — that would be quite dangerous.
“If we stop, then all our efforts will be wasted and we could potentially see a second peak.
Give now to The Sun's NHS appeal
BRITAIN’s four million NHS staff are on the frontline in the battle against coronavirus.
But while they are helping save lives, who is there to help them?
The Sun has launched an appeal to raise £1MILLION for NHS workers.
The Who Cares Wins Appeal aims to get vital support to staff in their hour of need.
We have teamed up with NHS Charities Together in their urgent Covid-19 Appeal to ensure the money gets to exactly who needs it.
The Sun is donating £50,000 and we would like YOU to help us raise a million pounds, to help THEM.
No matter how little you can spare, please donate today here
“So over time, probably over the next six months, we will have a three-week review, see where we are going, keep that lid on.
“Then gradually we will be able to hopefully adjust some of the social distancing measures and gradually get us back to normal.”
But she added: “And it is plausible that it could go much further than that.”
