Suppose that there is a viral epidemic following a classic SIR model in a certain region. What would be the effect of lockdown in this region?

1. It increases the value of $R_0$
2. It reduces the value of the recovery rate, which reduces $R_0$
3. It reduces the average degree, moving out from endemic state
4. It does not affect the current epidemic state
5. None of the above
