Before revision:  We use the asymptotic periodicity of Bessel functions , which readily provides the required; but the epidemic may resume . Practically: the hesitation before enabling some protection measures must be at least doubled before disabling them.
After revision:  We use the asymptotic periodicity of Bessel functions . Epidemics may resume after such saturation . Practically: the hesitation before enabling some protection measures must be at least doubled before disabling them.
