Closed rooms with many people talking are hot-beds of infection. Invisible clouds of virus hang suspended in the air. Open the windows. Turn up the airflow. Wear masks. (Wear goggles too, if you are high risk, the virus can get in through the wet surface of your eyes).
Blow that virus outdoors where the sun will fry it. We need to change the way we handle air in planes and on cruise ships, and public transport — even when there is no pandemic.
This is why I am not shopping without PPE. Make a mask. Mail order and delivery is so much safer. Do carpark pick ups. It’s also why eating uncooked fruit and vege that people may have breathed on is still a risk. The virus will likely survive 28 days in the fridge at 4 degrees C and even longer in the freezer. At 40 degrees it will last about 6 hours. Time will not protect you unless things are warm.
When I did research in a lab, if we wanted to save viruses we’d put them in a freezer (minus 70C).
A virus is more like a chemical than a living thing.

Heat helps bacteria but heat “kills” viruses by shaking them apart on a molecular level. I’m putting mail in plastic bags and leaving it in the Australian sun, or a hot car.
