Seesaw scenarios of lockdown for COVID-19 pandemic: Simulation and failure analysis.

• The behavior of epidemic on six benchmark networks is simulated. •.The geometric network was the best fit for contacts pattern in Qazvin province of Iran. • The effect of crucial parameters on behavior of the epidemic is discussed. • The effect of soft seesaw scenarios for lockdown is analyzed. • Soft seesaw lockdown scenarios are suitable alternatives in poor societies. The ongoing COVOD-19(SARS-CoV-2) outbreak has had a devastating impact on the economy, education and businesses. In this paper, the behavior of an epidemic is simulated on different contact networks. Herein, it is assumed that the infection may be transmitted at each contact from an infected person to a susceptible individual with a given probability. The probability of transmitting the disease may change due to the individuals' social behavior or interventions prescribed by the authorities. We utilized simulation on the contact networks to demonstrate how seesaw scenarios of lockdown can curb infection and level the pandemic without maximum pressure on the poor societies. Soft scenarios consist of closing businesses 2, 3, and 4 days in between with four levels of lockdown respected by 25%, 50%, 75%, and 100% of the population. The findings reveal that the outbreak can be flattened under softer alternatives instead of a doomsday scenario of complete lockdown. More specifically, it is turned out that proposed soft lockdown strategies can flatten up to 120% of the pandemic course. It is also revealed that transmission probability has a crucial role in the course of the infection, growth rate of the infection, and the number of infected individuals. [ABSTRACT FROM AUTHOR]
