How does a virus compare in size to a typical bacteria cell?

Answer 1

With a diameter of 220 nanometers, the measles virus is about 8 times smaller than E.coli bacteria.
At 45 nm, the hepatitis virus is about 40 times smaller than E.coli.
For a sense of how small this is, David R. Wessner, a professor of Biology at Davidson College, provides an analogy in a 2010 article published in the journal Nature Education: The polio virus, 30 nm across, is about 10,000 times smaller than a grain of salt. Such differences in size between viruses and bacteria provided the critical first clue of the virus' existence.

Answer 2

Viruses are much smaller than typical bacteria cells. They are usually between 10-100 times smaller in size, with the average virus measuring about 20-400 nanometers in diameter compared to a typical bacteria cell which can range from 1-10 micrometers.

Answer 3

a typical virus is at least two orders of magnitude smaller than a typical cell

Answer 4

Viruses are much smaller than cells.
