The Effectiveness of Ozone Therapy in the Prevention of COVID-19 Infection

The inclusion criteria were determined to be completed at least ten sessions of ozone therapy applied by the method of major autohemotherapy in the last six months from the time the first COVID-19 case of Turkey reported (Mar 11, 2020). Individuals who received ozone therapy locally or fewer than ten sessions, who did not want to participate were excluded.

The major autohemotherapy procedure to all the participants was applied as follows: 100mL of blood was drawn by a vacuum from the antecubital vein into a sterile glass bottle in which 12 mL of 3.13% sodium citrate solution as an anticoagulant (MediPac®, Germany). A corresponding volume (100mL) of gas with an ozone concentration of 10-20 µg/mL was immediately added and continuously mixed by a gentle rotating movement to avoid foaming to the blood in the bottle. Ozone was produced by a Blue-S medical ozone generator (Turkozone®, Turkey). Reinfusion was accomplished in about 15-20 minutes, and the whole procedure was carried out in approximately 30 minutes and was repeated two or three times a week.
