Preventing COVID-19 transmission is necessary and improved hygienic measures have contributed to saving countless patients. But the intersection of increasing hygienic practices, antibiotic consumption and recent COVID-19 pandemic control measures may negatively affect the microbiome and have consequences on human health.
This Biocodex Satellite Symposium, originally broadcasted on the e-Asia Pacific Digestive Week, discusses how: «improved sanitary conditions in the 21st century», «overconsumption of antibiotics» and «recent COVID-19 control measures» interact with human gut microbiome diversity and possibly affect the health of patients.

Program
First, Prof. F. Shanahan describes the evolution of a concept in immunology from the «hygiene hypothesis» to the «missing microbes» and briefly reminds the «knowns» and «unknowns» in microbiome science (5’ talk).
Prof. M. Blaser then develops, in a three parts presentation, his theory of the «missing microbes» and how sanitary measures and antibiotics intake induce the loss of gut microbiota diversity (20’ talk).
Finally, Prof. F. Guarner describes the importance of gut microbiota and microbial exposure in gastrointestinal immunity (15’ talk).
The symposium ends with a 15’ roundtable moderated by Prof. F. Shanahan discussing more specifically the COVID epidemic potential impact on the diversity of gut microbiome and the emergence of gastrointestinal issues.
