Background: Coronavirus, called as, “the worst public health crisis for a generation,” is a
malevolent silent killer.
Objective: One of the main concerns is containing the disease and avoiding the second wave of the pandemic,
likely to arise because of the symptomatic patients, while ensuring the safe execution of day to
Methods: The indirect transmission of coronavirus from asymptomatic individuals during incubation
time and the identification of the people who have accidentally and unknowingly come in contact with
infected but asymptomatic patients pose a significant challenge to the health care providers.
Result: Herein, for the first time, we have introduced a quantitative index; asymptomatic growth, to indicate
whether the COVID-19 community spread is under control and if economic activities can be resumed.
Conclusion: More importantly, our system provides a feasible mechanism for improving the index to a
level <1, a safety level at which normal economic activities can be conducted.
