What does R0 mean?

It means how contagious a disease is by its basic reproduction number, referred to as R0 (pronounced “R nought”). The R0 refers to how many people a single infected person will infect in a population.

The R0 is calculated based on how fast an outbreak grows, how long it takes for a person exposed to the virus to become contagious (latent period), and how long an infected person is contagious (infectious period). The longer someone is contagious, the higher the R0 is.
