By reducing human to human contact, plus good hygiene we reduce the chance of it finding hosts, to the degree that one person with virus spreads it, on average, to less than one person, so eventually it can’t find hosts and disappears. The balance easing lockdown is to ensure that we keep the chances of it infecting people under control...ie R less than 1
