Prospective Study Evaluating the Olfactory Recovery of Anosmia Post COVID-19 by Olfactory Rehabilitation Assisted by Web-application

Anosmia is a symptom present in 40 to 80% of patients and usually only lasts 1 to 2 weeks. 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. A web-application to support the olfactory coaching of anosmic patients and help with follow-up seems relevant to promote recovery and the proper conduct of this coaching.

covidanosmie.fr is a web application dedicated to olfactory rehabilitation, accessible free of charge.
