For the last 3 winters I had a granddaughter living here with us that was an RN and she worked at the local hospital. Now and then she would be catching some bug or other. I would immediately start running my cool-mist humidifier filled with 10 ppm Colloidal Silver (home made). I would let it run all day and all night so each family member would be breathing the CS. No one ever got any sicker, nor get sick, when I used this method.
Very nice preventive.
Hopefully this will work to prevent Ebola..........
