Since the beginning of the SARS-CoV-2 pandemic, health authorities have been advocating for the generalization of non-pharmaceutical measures to fight the spread of the disease. Such measures such as physical distancing, mask wearing, tightened basic hygiene, quarantine and even curfews are effective to limit the transmission of SARS-CoV-2 and to decrease the virus reproductive number R0. At the same time, these measures have had a drastic effect on influenza viruses and RSV, which are currently absent. In contrast and surprisingly, Rhinoviruses continue to circulate but in younger people, unlike in previous years when they were found in all age groups. The effectiveness of non-pharmaceutical measures is therefore not uniform and depends on the epidemiology of pathogens, their incidence and circulation This article is protected by copyright.
