From this data, researchers calculated a median R 0 value of 5.
An R0 of 2 means that each person with the disease infects two others.
R 0 is an indicator of the contagiousness or transmissibility of infectious and parasitic agents and represent the number of new infections estimated to stem from a single case in a population that has never seen the disease before.
Contact Rate This refers to how many people a person with the disease can be expected to come into contact with.
R0, pronounced R-naught, relates to the reproduction number and is used to gauge how likely the outbreak is to spread.
The measure allows modellers to work out the extent of the spread, but not the speed at which the infection grows.
