COVID-19: launch of an international survey on the loss of smell and taste

Many patients with Covid-19 experience a loss of taste (ageusia) and/or smell (anosmia). More than 500 researchers from 38 countries have therefore joined forces to study this phenomenon within the Global Consortium for Chemosensory Research (GCCR). French laboratories and organizations¹ invested in the GCCR will have their efforts coordinated by Jérôme Golebiowski, a Université Côte d'Azur professor at the Nice Institute of Chemistry (CNRS/Université Côte d'Azur) and director of the CNRS ‘Odorant-Odeur-Olfaction’ research group. Today the consortium is launching a major international survey in the form of a short questionnaire (available in more than 20 languages) aimed at current or recovered Covid-19 patients. The scientists' priority is to evaluate the frequency and nature of ageusia and anosmia cases among those affected, compare them to other pathologies and initiate a medium- and long-term follow-up.

Participation in this survey is voluntary and takes about 10-15 minutes. The data will remain completely anonymous and will be stored on secure sites. Please note that this survey is not intended to establish a diagnosis and does not propose a treatment.
