I WONDER - How Big Are Viruses?

The video explains that viruses are much smaller than bacteria and require an electron microscope to be seen. Viruses range from 0.02 to 0.3 micrometers, while bacteria are 1 to 10 micrometers. Antibiotics are ineffective against viruses, which require antiviral medications for treatment, though not all viruses can be treated this way.

What is the typical size range of bacteria?

Can all viruses be treated with antiviral medications? Explain.
