"Well you should not worry about passing it on as it is down to others to isolate if they are worried about catching it" Ultimately, I suppose you could say we each have to make our own provision to ensure our own safety. But to put the responsibility for staying safe entirely on those concerned about catching the virus is entirely wrong. Perhaps you didn't mean to write that. If a jogger brushing past me without warning and without distancing is my responsibility/problem, with jogger having no responsibility, that doesn't sound like social responsibility to me. I would hope that every person SHOULD worry about passing the virus on, no ? In fact, hasn't "control the virus" actually been the core of the Govt's advice ?!
