Hypothesis of the beneficial effects of preventive immunobiotic intervention on SARS-CoV-2 infection. The kinetics and intensity of immune actors involved in the response to SARS-CoV-2, viral load and COVID-19 severity are shown according to Jamilloux et al. (2020) in both “mild/moderate” and “severe” susceptible hosts. Optimal times for therapeutic interventions proposed to ameliorate disease severity are also shown (left panels). The potential modulation of the kinetics and intensity of immune response, viral load, and disease severity by preventive nutritional immunobiotic interventions for low and high susceptible hosts are shown in the right panels.
