i would use CDS (From MMS) 2nd. This is what i would use first: 100% COVID Cured and fast. All of the COVID patients reported significant improvement after the completion of the first 30 minutes of nebulization, including near-immediate improvement in the ease of breathing by those who had the most advanced infections. Food grade H202 Hydrogen Peroxide nebulization overcomes this lack of supplementation access, and it is the only therapy that can resolve COVID as a monotherapy. With 6,000 references about healing. A $15 USB powered cool mist Ultrasonic humidifier and start with 1% food grade H202 Hydrogen Peroxide. Some cool mist are low rate evaporative, buy only the Ultrasonic humidifier. http://orthomolecular.org/resources/omns/v16n43.shtml
