COVID Transmission Rate (R0)

The R0 number describes how easily a disease is spread from one person to another. An R0 of 2 means that a single person is likely to give the disease to 2 other people if no precautions are taken.

The infographic below is from March 2020. It still seems to be reasonably accurate. There are now higher estimates for both R0 and Case Fatality Rates.

See here for more comparisons.
