The video shows that germs can be anywhere on public surfaces. At the moment, we are particularly concerned with Covid19 but this applies equally to colds, flu, gastro bugs, and so on.

Protecting yourself from coronavirus

You are much more likely to get sick from touching a contaminated surface and then touching your eyes, nose or mouth than you are by breathing in virus particles in the air.

The best way to protect yourself is, obviously, to not go out into public areas. Staying at home and keeping social contact to a minimum is, by far, your best option.

If you must go out, treat every surface as suspicious. Every shopping trolley, every hand rail, every shop counter, every EFTPOS machine could be contaminated with virus particles. 

Wash your hands often. Don’t touch your eyes, nose or mouth.

If you can’t wash your hands, use hand sanitiser, but be aware that this may not be as effective.
