Annales 80.2 - Prevention of allergies in the post-pandemic era

 The COVID-19 pandemic has drastically changed human activities across the world in efforts to minimize risks relating to the disease, especially when it came to social distancing and practices related to disinfection. This may have affected human immune system and the environmental microbiota interactions, thus affecting how allergies develop. In this issue, we review the impacts of the COVID-19 infections on those with allergies, how pandemic measures might have changed the exposome and its effects on the immune system of those born in the time of the pandemic, how neonates may develop a healthy intestinal microbiome that may promote a balanced immune system, and how maternal diet and early infant feeding practice may influence the subsequent development of food allergy.
