I genuinely not snarkingly think I am missing something, can anyone help.
The plan is to flatten the curve and the main measure is that people with a cough and or fever self isolate for seven days, or longer if symptoms persist. The household members need not isolate.
So that would mean that the following people are still out and about or risk infecting people if they have the virus-
People who have not heard the message or advice.
People who heard it but did not understand it or take it on board.
People who heard it but are not willing to comply, or intend to but don't due to pressures of daily life.
People who try to comply but don't manage to do it properly, through not fully understanding or achieving the conditions needed to self isolate effectively.
Household members who are not yet symptomatic but very likely infected.
People who have the virus but do not have symptoms at any point or whose symptoms don't fit the description.
People who are about to become symptomatic and are highly infectious but not yet experiencing anything to signal to them to isolate.
I am sure I have missed many categories there, but the point is it seems to leave a tiny subset of the people who are actually infectious in a situation where they are effectively isolating. Looking at the way this virus is tearing through other countries I just can't see this having much impact to even flatten the curve.
