Transmissibility changes for different receptor binding complexity and host protein mutation rate. The mean transmissibility (ξ) for the last 250 time points (Error bar: one std. dev. over 100 simulations). ξ increases as the receptor binding complexity decreases (shorter L) in which case viruses can target multiple receptors and as the host protein mutation rate (μ _hp ) decreases which is due to the more limited speed of protein mutations to counteract the rapidly evolving viruses
