It is important to appreciate that in epidemics we can only protect ourselves, our families and our children in one of two ways.
We can only develop immunity in one of two ways. We can either be infected, which carries the risk of illness, complications and even death or we can be vaccinated.
The public health measures in any epidemic are aimed at slowing down both the rate of progression and ultimate size of the epidemic.
In addition, the measures above may be expected to reduce other coexisting infectious illnesses (Influenza, common colds etc.). This can boost population immunity which reduces the likelihood of an epidemic taking hold. We have a further article explaining how the public health measures work in more detail here.
