Loss of smell and taste related to infections of the upper respiratory tract 


To learn more about olfactory disorders after upper respiratory tract infections, e.g. after a flu-like infection or also after infections in connection with the Corona pandemic and COVID-19, we ask you to fill in this questionnaire (duration approx. 8 min). Even if you have not had an infection, you can still participate in our survey. At the end of the survey, a short self-test is also included to test your sense of smell.
