I don't think you need to quarantine in different houses.  For most illnesses, if you treat your house like a hospital environment, that does fine.  

That's your basic stuff, keep your distances, wash hands, cover coughs, isolate at dinner, private bathroom or sterilize after each use  etc.  Worse offender is don't sleep in the same bed.  

The real SHTF problem is the older we get the more likely common viral complaints turn into secondary bacterial problems.  We can try to prevent this by limiting nasal drip into our lungs with over the counter meds and old school frequent blowing of our noses, but eventually once its bacterial, we're talking antibiotics.  Some of this stuff, older you are, you just can't fight it off and though you may be functional, you can be carrier spreading your infection.  We often refer to that as "Walking pneumonia".  The actual diplococcus responsible for pneumonia is very communicable but fortunately very susceptible to antibiotics.  

Now I know in this current atmosphere what I posted seems almost unreal, but you need to know families lived with TB patients for generations without transmitting the disease.  It just requires care and a very conscious effort on the part of the person with the infection.  Before the cure, TB was a very terrible thing.  My grandfather had it then.  A tall thin man always without exception a handkerchief in hand, today in retrospect he reminded me of a movie Doc Holiday, but the point was he was already ready to control his sputum spray.  He was careful of where he spit, what he touched, etc.  Long story very short, he was finally interned in a Sanatorium there to live till he died.  Despite the sunshine and trees when we'd visit, I could never shake the feeling that those were dark horrible places of slow agonizing death.  My grandfather wrote a poem, "The White Room" which was featured on the Lawrence Welk show.  Welk was an old friend from his youth.  The poem was about this "White Room" all TB patients were eventually moved to in a Sanitarium there never to leave, a dying room.  What I'm getting at here is measures can be taken because as dark as that place was, it was staffed by folks who didn't get the disease.  BTW, This was the 60's and my grandfather lived to take the cure and go home.  

I'm a major history buff.  That same grandfather was a history teacher.  I'm reading a book now on 17th Century Japan.  Over the years of talking history, I've been often asked what era in history I'd rather live if I could go back in history.  My answer often shocks people.  "Save your time machine, none, but the one I lived, because I have no desire to live any time in history before antibiotics."  

We talk SHTF/EOTWAWKI but few of us are actually prepared, even know what to do, or even dare to think of it in a world without antibiotics.  Those were times when a cut could mean your death and the only measure to cut off a limb.  Abdominal problems were  were make them comfortable and pray with the wiser get a grave dug.  Even as a boy in the 60s, I use to listen to my great grandmother about post Civil War times and shiver at the unnecessary death by post antibiotic standards.  I'll give you an example.  How many of you guys when you scratch your leg on something as simple as a thorn stop and put iodine on the scratch?  There's a chance that little scratch can mean an arm or a leg.  This type thing influenced dress in history and it wasn't just modesty that made long sleeves and long pants so popular.  

Even today, iodine is a must have in my preps even if all it does is prevent having to bandage, use an antiseptic ointment, and continual changing.  Don't let it get that far.  Get that far before antibiotics, all it was was a sniff from a nose and your leg was taken.  

Why do I bring this up?  Its the same thing.  That prevention saves you the reaction.  We're a reactive society now.  We go through life without concern knowing there is most likely a cure.  If there truly is some horrible pandemic, our learning curves going to kill countless numbers.  There's not much we can do controlling our schools, places of work, public places, but we can practice stepping back in time within your home. A time when one person in a household takes ill, not everyone else has to.

Well guys, I don't think you are throwing your shit out a window down to the open sewers anymore or are ignorant of how germs transmit.  

In fact, in some sort of pandemic sending you family members off in a bunch of different directions is about the worse thing you can do.  It would encourage spread by taking people from known infected houses to other houses and you lose control of what health practices are deployed, sterilization etc.  You could be moving your family member from a house using good practices to a bad one.  

They use to bleed people and burn the dead's houses too.

in such situations. rest, fluids, nutrition and let their natural immune system deal with it. monitor fever and treat accordingly if needed.

beyond that there really is not a lot you can do that will be that effective. antibiotics may do nothing at all and in some cases may cause other issues if you get the wrong ones. people rely way to heavily on them today. the immune system is VERY good at what it does. let it work.
