Fig. 2From: What is the role of aerosol transmission in SARS-Cov-2 Omicron spread in Shanghai?Transmission diagram of Omicron in Shanghai. The yellow compartments represent the infection process of the unvaccinated, and the green compartments represent the infection process after vaccination. Therein, the force of infection for a susceptible individual is approximated as \(\lambda (t)=-(\beta (t)+f\xi )\dfrac{\theta (A_s+A_v)+I_s+I_v}{S+V+E_s+E_v+A_s+A_v+I_s+I_v}\)Back to article page
