Bacteria are microscopic, single-celled organisms. Many don't cause disease and are even beneficial, although some are disease-causing (pathogenic).
Viruses are even smaller than bacteria. Viruses can't reproduce without a host.
So, do paper, and even cloth masks, prevent the spread of the Covid-19 "germs"?

Masks do work to lessen the transmission of the virus. Masks block the droplets that contain the virus. The virus, although microscopic, does not travel on its own.
