Disinfectant wipes don’t kill viruses. But they reduce the virus load by the act of manually wiping them away, and they kill a lot of fungi and bacteria.. I hadn’t thought of the nasal spray, but it makes sense. I find taking zinc before and during a trip helps avoid catching other people’s bugs. My last trip to America, I spent ten days in a house with three people suffering with flu like symptoms, and I was healthy all the way through becaus my fiancé made me take zinc every day.

i to wipe down arm rests, tray tables and other hard surfaces when I board. And I never get sick when I fly. Other than motion sickness occasionally.
