Formula

SIR Model: dS/dt = -βSI; dI/dt = βSI - γI; dR/dt = γI; R₀ = β/γ
  • Viral Infection Sir calculates its result from Betasi, Gammai, Beta β, Gamma γ. It uses the formula SIR Model: dS/dt = -βSI; dI/dt = βSI - γI; dR/dt = γI; R₀ = β/γ. Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
  • The main inputs are Betasi, Gammai, Beta β, Gamma γ. Enter them in the units and format shown in the calculator.
  • Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Viral Infection Sir

Inputs
  • Betasi: 2
  • Gammai: 3
  • Beta β: 4
  • Gamma γ: 5

Using Betasi = 2, Gammai = 3, Beta β = 4, Gamma γ = 5, the calculated result is 0.8.
