Yes I agree, nasal sprays like providone mix or xclear appear to really make a difference. I use when traveling on planes or in large crowds- parties, funerals, church, weddings or at first sign of scratchy throat. That being said, I quickly do a preventive dose of ivermectin, D, C, zinc too. The combination really works. I just do not get sick anymore. I used to get sick after every flight and several colds a year. Not since doing this. Daily spray would be even better, but many days I work alone and outside. My husband refuses the nasal sprays and is on day 7 of a cold now...
