SIR model according to changes in the perceived risk of infection (A) \({r}_{i}=0\), (B) \({r}_{i}=3\), (C) \({r}_{i}=5\), and (D) \({r}_{i}=10\). As the general behavioural dynamics of the epidemic population \({{S}}=({{{S}}}_{{{V}}}+{{{S}}}_{{{U}}})\), \({{I}}=({{{I}}}_{{{V}}}+{{{I}}}_{{{U}}})\), \({{R}}\), and \({{{r}}}_{{{i}}}\) increase, the individual’s strategy frequently changes. Based on variations in the infection wave for various disease recognition values \({{{r}}}_{{{i}}}\), the initial infection peak is low if the value is high, and a vibration term is generated to disperse the number of confirmed patients. This parameter significantly influences the infection peak size, decreasing it while spreading the cases across several smaller infection waves.
