Do the air think periodically, get lots of air in, shake things out, don't leave it open and sit there for hours. Even wrapped up very warm, the cold air itself is perfect temperature right now to carry and preserve Covid and other virus. And just breathing cold air will result in a lower blood flow - particularly to your nose. Lower chance the virus is stopped at source by whites and tcells. Already known to be true of all rhino and coronas pre covid.
Ahh. I tried all this. Didn't work for me. The only thing I can really say is we have loads of us here using tiny corridors, 1m by 6m by 7ft. Dozens of kids, families in flats too small, parents remarried to remarried parents, layers of step families mixing in other places. Also Hospital workers.
The only thing I would say is, I wish I'd not been the only one to wear the mask in communal areas. On the street. It's just likely to have been the only thing that went wrong here. People are heard coughing in the corridors. Out of windows is one thing I guess. But spitting on the floor? Dammit guys.
Leave your communal windows open. I always opened one, and it was always shut by the next resident. That stopped in November, when the tests ominously started turning up outside the last few people's houses.
Seemingly everyone but a select few of these 100 houses and flats here will have had something flu like this year. Some never stopped coughing and spitting on the ground or smoking. Now I've got a permanent cough. And of late, a permanent runny nose. It wants wiping all the damn time.
That is the clever by accident virus we have. The variants that make you cough but you're not really aware of it are the ones that get spread without thinking. You'd barely know you had a cough. At first. Then 6 months later you realise the sore throat might never go back to normal. Same thing with the runny nose. It just drips, hardly a stuffy cold. I found myself wiping it on my sleeve - and I know better. Then, it turned into sore eyes and an aching sore nose. Still no green stuff. And still just that gentle drip tempting you to use your sleeve, or your hand.
Ultimately, after months of this on and off, very low key, I've ended up with a virus scar like measles right on the apex of my right nostril. I can feel the damn nerve or whatever that goes right up into that eye, and back down to the root canal underneath it. It's like if you get a permanent slight weak spot on your chest from smoking and infection.
It comes without any big symptoms, just gets you coughing absently, wiping your nose, gets a bit worse, and by the end you can have had a proper mare on the quiet, and if you're like me, you now have what seems to be the permanent additions of a gravelly husky voice, and a load of very slight, less desirable stuff.
