Coronavirus lingers in air longer than previously thought, scientists claim

Coronavirus: 'Desperately ill and struggling to breathe' - Inside Spanish ICU treating COVID-19 patients

For their study, researchers modelled the airborne movement of aerosol particles smaller than 20 micrometres. For a dry cough, which is a typical symptom of COVID-19, the particle size is typically less than 15 micrometres.The particles could end up in the respiratory tract of others in the vicinity, researchers said"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 researchers said.

The Finnish scientists said the spread of a virus may slow down or even be suppressed altogether as mobility decreases at"nodal points" - places where lots of people gather, such as shops, restaurants and public transport. They added that avoiding busy indoor areas reduces the risk of droplet infection while in close proximity to others, which is the main cause of coronavirus infection.

Hi. Those are good results describing indoor conditions. Here we include the effect of micro-scale wind over droplet propagation:

Always something appears to keep the fear levels at peak.

Our Asda has trolley cleaning station, but you must first get your trolley, contaminate your hands, then use a spray bottle again contaminating your hands. Thirdly you have to handle a big roll of blueroll so again contamination and lastly remove a lid from a bin to dispose.

If you have a cough you should not under any circumstances leave your home. So this model is moot.

Yh cheers I’m just at work atm cannot wait for my anxiety to go through the roof when we open Jesus 🙈

This is why we ALL need to wear a mask, won't stop you getting it, but may stop you spreading it, surely something is better than nothing.

If your coughing like that though,,, you need to be arrested.

wE All need eaCH OTHER At thos TIMe

Yes'that's how the common cold spreads

wOW..

Make no mistake. Supermarkets are infection central and the system they have implemented of long queues and one way systems that keep people in there will be one of the big inquiry points.

New data analysis by prestige academics suggests we switch to a less self-destructive approach toward COVID19.

I live in Bangkok and every public building like supermarkets has someone taking your temperature, hand sanitiser at the door and a man sprays and wipes the trolly handle before you handle it. So simple and so effective.
