The average number of people that one person with COVID-19 can directly infect is ~ 2.5

There is simple math behind the power of social distancing.

Generally, each COVID-19 patient can infect ~2.5 others. There are ~5 days between one infection and next, so each infected person can infect 244 others in a month.

If by practicing social distancing, we reduce the transmission by half, so each person infects 1.25 others, we'd expect only 4 more cases.
