  The ongoing COVID-19 pandemic has affected most of the countries on Earth. It
has become a pandemic outbreak with more than 24 million confirmed infections
and above 840 thousand deaths worldwide. In this study, we consider a
mathematical model on COVID-19 transmission with the prosocial awareness
effect. The proposed model can have four equilibrium states based on different
parametric conditions. The local and global stability conditions for awareness
free, disease-free equilibrium is studied. Using Lyapunov function theory and
LaSalle Invariance Principle, the disease-free equilibrium is shown globally
asymptotically stable under some parametric constraints. The existence of
unique awareness free, endemic equilibrium and unique endemic equilibrium is
presented. We calibrate our proposed model parameters to fit daily cases and
deaths from Colombia. Sensitivity analysis indicates that the transmission rate
and learning factor related to awareness of susceptibles are very crucial for
reduction in disease related deaths. Finally, we assess the impact of prosocial
awareness during the outbreak and compare this strategy with popular control
measures. Results indicate that prosocial awareness has competitive potential
to flatten the curve.
