R0 Calculator

Formula

The formula to calculate the Basic Reproduction Number (R0) is:

\[ R0 = t \times c \times d \]

Where:

\(R0\) is the basic reproduction number
\(t\) is the transmissibility (infections per contact)
\(c\) is the rate of contact (contact per time)
\(d\) is the total time of infectiousness (time per infection)

What is R0?

R0 is a symbol used to denote the primary reproductive number of an infection. This value represents the total number of expected secondary cases produced by a single infection in a susceptible population.

Example Calculation

Let's assume the following values:

Transmissibility (t) = 0.5 infections per contact
Rate of Contact (c) = 10 contact per day
Total Time of Infectiousness (d) = 7 days

Using the formula to calculate the Basic Reproduction Number (R0):

\[ R0 = t \times c \times d = 0.5 \times 10 \times 7 = 35 \]

The Basic Reproduction Number (R0) is 35.
