Conclusion
This study showed that overall frequency of SARS-COC2 infection in
participants receiving synbiotic and those receiving placebo did not
differ significantly. However, 3 hospital staff in placebo group
compared to no one in synbiotic group had SARS-COC2 infection. This is
encouraging regarding the importance of morbidity and mortality of
COVID-19 especially in health care workers. Further studies with greater
power and alternative probiotic strains and mixture are warranted to
determine whether Synbiotic can prevent COVID-19 in at-risk hospital
staff.
