Average predicted long-term effect of COVID-19 on the Karisoke mountain gorilla subpopulation when the basic reproductive number is R₀ = 3 and the maximum immunity probability is M_I = 0.2 for four scenarios resulting from the combination of an immunity duration (T_I) of 3 or 12 months and maximum infected mortality probability (q_M) of 0.3 or 0.6.
