Hi pink - and absolutely.
The trouble with airborne viruses is that where you get big groups of people together, obviously it makes the chances of catching whatever higher, but this really can't be avoided.
If no one went to school, college, uni, work places, shopping etc., etc., the country'd grind to a disastrous halt.
The medical and security personnel need to come first, followed by anyone in the high-risk group, but the flu's already spreading, and you could pass someone in the street with it and be unaware. Short of cordoning off every hamlet, village and town, so that each area becomes like the Plague Village once did, then I believe that we'll just have to sit it out and do the best we can with the resources available.
