Several studies analyzed the mechanisms by which ozone therapy could combat viral infections. In particular, 1) the improvement of the release of oxygen in the peripheral tissues, 2) the anti-inflammatory action 3) a virucidal activity have been described.
In view of these properties, a number of international clinical trials on the topic are currently ongoing.
Hospitalization, dietary changes, use of antibiotics and systemic inflammation related to COVID-19 are all variables that contribute to changes in the intestinal and lung microbiota with significant repercussions on the outcomes of the disease. Furthermore, the use of ozone therapy could also lead to a modification of the microbial flora. Probiotic supplementation can help to correct these issues.
