Sorry, can you explain that for me then please? It sounded like you said the virus can remain in the air for at least 3 hours.

 

 

I think @tree-fancier123 has covered it.

 

As I read it most infected people out in the open air will cough out relatively large droplets, the chance of breathing one in will be small beyond 2 metres. In other, indoor, situations where droplets may be smaller ( I don't know why but they mention hospital procedures) the virus stays in the air and half of them disappear after 3 hours, it would take a further 3 hours to half the remainder and so on.

 

Now this may have limited consequence to most of us while only a small proportion of the public are infected and in the environment, where droplets and contact with surfaces will remain the main means of infection but with doctors and nurses up close and personal it looks like it becomes significant.

 

IMO they should only be examining people with a full hood, just like those Porton Down technicians did in Salisbury and not worry what the patient thinks.

Well first day had a job put on hold until further notice..job was to reduce conifers for Hasall Construction Ltd who are based in Bath..they have shut there site down in Droitwich..but I just wanted to give them a shout because they have agreed to pay me the full amount and obviously do the job when possible which could be god know when so fair play to them for paying now as they didn’t need to do that.?

The WHO says that "according to current evidence," the virus is transmitted through "respiratory droplets and contact routes." By that, the agency means the virus is found in the kind of big droplets of mucus or saliva created through coughing and sneezing.

These droplets can travel only short distances through the air and either land on people or land on surfaces that people later touch. Stopping this kind of transmission is why public health officials urge people to wash hands frequently and not touch the face, because that could bring the virus into contact with the nose or mouth.

 

Other viruses, however, get shed by infected people in a way that lets the germs actually hang suspended in the air for minutes or even hours. Later, these airborne viruses can get breathed in when other people pass by. Measles is a good example of that kind of transmission — the Centers for Disease Control and Prevention says, "Measles virus can remain infectious in the air for up to two hours after an infected person leaves an area."

 

 

Among patients infected with SARS-CoV-2, viral loads in the upper respiratory tract are high; as a consequence, respiratory secretion in the form of aerosols (<5 µm) or droplets (>5 µm) is likely, the authors note.

van Doremalen and colleagues used nebulizers to generate aerosols. Samples of SARS-CoV-1 and SARS-CoV-2 were collecting at 0, 30, 60, 120, and 180 minutes on a gelatin filter. The researchers then tested the infectivity of the viruses on Vero cells grown in culture.

They found that SARS-CoV-2 was largely stable through the full 180-minute test, with only a slight decline at 3 hours. This time course is similar to that of SARS-CoV-1; both viruses have a median half-life in aerosols of 2.7 hours (range, 1.65 hr for SARS-CoV-1, vs 7.24 hr for SARS-CoV-2).

 

they have to do the research, but then release the results in a way that won't make people too worried, difficult job

 

Hence a good strong mouthwash, you can wipe yr arse on that toilet paper nonsense ?  k

That doesn't sound too good at all! Let's hope the hospital workers get some much needed appropriate PPE supplies asap.

when you think about the morbid last hours of someone dying from C-19 it is like drowning in their own mucus - oxygen starvation, then heart and kidney decline and failure. Soo it occured to me a novel high tech cure would be to get the blood out of the patient through a cannula and into an artificial lung that does the gas exchange instead of the lungs, preferably a device that could work of power tool batteries so the patient could walk about. 

Not quite so far fetched, but an encouraging developement in the news today

'A non-invasive breathing aid that can help to keep coronavirus patients from needing intensive care has been developed and approved in a matter of a few days.

The device, known as continuous positive airway pressure (CPAP), was created by a partnership between the Mercedes Formula One team, University College London (UCL) and University College London Hospital (UCLH).

CPAP devices work by pushing a mix of oxygen and air into the mouth and nose at a continuous rate, thereby increasing the amount of oxygen that gets into the lungs. They bridge the gap between an oxygen mask and the need for full mechanical ventilation, during which the patient must be sedated.'

 

PS last time I saw someone spitting on their hand cant remember the name of the film..

Basically thats scuba gear. Yr regulator in yr mouth will pressurise yr lungs as much as you can suck. Come to Essex if the hand thing still doesnt make sense ?  K

The number of staff members that patients interact with is scary, once you take into account nurses, catering staff, domestics and cleaners. As a patient it's better not to begin to calculate how many people all of these have come into contact with outside of the hospital.

What's the situation with the virus spreading further outside? I don't by the two metre distance when outside because surely a slight breeze can take the droplets much further, just like the case with tree diseases spreading miles with the wind.

Its 1m indoors and 2m outdoors. Its a balancing act between being unmanageable and having a working system. The advice to not to go out at all really and avoid all contact. Not sure if it would still work being carried on the wind for miles and then landing directly in your mouth or eyes? Sounds highly unlikely and if that was the case Im sure we'd all have it by now. Certainly every single person within a hospital would, or everyone who's been on a train, flight, cruise ship, hotel etc with a confirmed case. Which is not happening.
