However, in nearly one in five patients, it can last beyond or even several months with consequences in terms of undernutrition and depression. However, olfactory rehabilitation is a technique validated in post-infectious anosmia since 2014 and recommended by international learned societies to accelerate recovery with nearly 63% improvement in anosmia In the context of the health crisis linked to the coronavirus, approximately 1 million French people will have persistent anosmia following an infection with COVID-19.
