How Efficient Can Non-Professional MasksSuppress COVID-19 Pandemic?	2020-06-03		.txt	text/plain	3731	214	58	Monte Carlo simulations exhibit that the effective reproduction number R of COVID-19 or similar pandemics can be approximately reduced by factor {gamma}4 with respect to the basic reproduction number R0,if the face masks with 70% <{gamma}< 90% are universally applied for the entire network. Furthermore, thought experiments and practical exploitation examples in country-level and city-level are enumerated and discussed to support our discovery in this study and indicate that the outbreak of a COVID-19 like pandemic can be even suppressed by the low efficiency non-professional face masks. In this study, abstracting physical and statistical models are our major methodologies for simulating a social network, in which the COVID-19 pandemic starts to be suppressed with the usage of different non-professional face masks. As an extension of Fig. 4 , we start the Monte Carlo simulations to study the effect of Class A+ face masks in the social network to suppress COVID-19 for longer period, when face masks obligation is applied at different stages of the pandemic.	./cache/cord-355700-1yf1ae1d.txt	./txt/cord-355700-1yf1ae1d.txt
