Does virus or bacteria spread faster?

Humans produce a new generation every 20 years or so; bacteria do it every 20 to 30 minutes, and viruses even faster. Because they reproduce so quickly, microorganisms can assemble in enormous numbers with great variety in their communities.

This is important to understand, because bacterial and viral infections must be treated differently. Misusing antibiotics to treat viral infections contributes to the problem of antibiotic resistance.

Why are viruses more contagious than bacteria?

Viral infections are more contagious because of how they reproduce. A single vrion can create thousands of copys in one cycle. Bacteria reproduce by budding, which is genetically much more resource intensive than the hijacking method viruses use.
