Multiplies per-contact transmission probability, effective contacts per day and infectious
Multiplies per-contact transmission probability, effective contacts per day and infectious duration to obtain a simple basic reproduction number, then applies a susceptible fraction for an effective number. It is a classroom homogeneous-mixing calculation, not an outbreak estimate, fitted epidemiological model or public-health forecast.
