How easy is it really to transmit Covid-19?

[YaWeeSkitter]

The social distancing warnings about 2 metre , 1 metre or 1 metre plus drift on.
People have to go to work and yes children really should be going back to school for their overall health and wellbeing. But there still lurks that fear that maybe we will brush past someone who has 'it' and be struck down ourselves.
There are tales of catching the virus from surfaces as an infected person had previously touched it .There are animations showing people on the tube casting off Virus particles in all directions by not wearing a mask.

But what confuses me is that to find out if you have the virus you must subject yourself to an uncomfortable and often difficult test that ,because its uncomfortable and difficult ,has a high negative rate.

So if its so easy to cast off why is the test so hard to carry out?

This is a genuine query and one that has been bothering me for a couple of weeks now since a family member came down with flu like symptoms and had to be tested.

Well I didn't get it off my own boyfriend. Unless I have immunity somehow.

Or you had an asymptomatic case. Some studies suggest a majority of cases are asymptomatic.

@sparepantsandtoothbrush

The test isn't physically difficult or particularly uncomfortable.

I had it in hospital and it was certainly unpleasant when done bu a professional, right up the nose

The virus is at the top of the respiratory tract (different to other SARS ) and you project it out. It’s the coughing that does it but a study also found heavy breathing, singing increases likelihood of infection.

Study also showed high spreaders eg 20 people v none so disparate based on place (crowded indoor upping it)

The test does sound hard but I presume you need to go far back to get closer to where it sits

All picked up from various R4 reports, so from memory scientists could add more.

Can anyone scientific explain what the difference is between having it asymptomatically, and never having it, in the cases of those whove been in close contact with partners etc whove definitely had it.

Are some people immune meaning they csnt get it, or does immunity mean you dont get symptoms.

I dont understand how the virus works with these people.

Also saliva test being trialled atm (fingers crossed it works)

I think Asymptomatic means you have the virus without having any symptoms. These people may spread it without knowing they have it. People who are immune don't get the virus as their immune system deals with it.

No I tested negative after he tested positive.
