Table 1. The game matrix between the government and the public in major public health emergencies.

Strategy Choice		Public
		Active Isolation (C)	Arbitrary Flow (F)
Government	Emergency Response (U)	(−c, −a)	$(-c-p_2\bullet L,-b-\frac{p_2\bullet L}{n})$
	Laissez-faire (I)	(0, −a)	$(-p_1\bullet L,-\frac{p_1\bullet L}{n})$

Based on evolutionary game theory and combining the four strategy combinations of the government and the public in the face of the major epidemic, the payoff matrix of the game between the two sides is obtained.
