(OMNS May 10, 2021) Recently I took some time off to visit family and friends in Cali, Colombia. During a trip a year and a half ago, I had met a friend of my wife who was in the early stages of what appeared to be a cold, but also possibly an early influenza. My wife said it looked like a typical case of "grippe," the Colombian term for an acute febrile respiratory infection that often proceeds to full-blown influenza. As I had already been experimenting on myself for nearly a year with the nebulization of a number of agents in various combinations for my own chronic sinus and throat problems, I had my nebulizer with me to help me deal with the many pathogens one often encounters in traveling.
