  Sorry, I don’t know the answer. What I know is our cells are very small and need a microscope to visualise them, germs are smaller than human cells, molecular machines that germs use to live in our body and cause diseases are smaller than the germs and some friendly viruses that can kill the notorious germs are even smaller than the germs!
