As reported by the study coordinator Marta Ochoa, a neurologist at HM Hospitales, only 10 percent of of the people surveyed found that they had problems with their sense of smell two months after the infection. In the case of several people, it was confirmed that they did not regain their sense of smell even after six months after contracting COVID-19.
The authors of the study indicated that anosmia appears on average three days after coronavirus infection and lasts for 23 days.
Study participants observed that some patients regained their sense of smell, but developed chronic olfactory disturbances.
The study by Ochoa’s team has already been presented at scientific conferences organized by the Spanish Neurological Society (SEN), as well as at the 19st National COVID-XNUMX Congress in Madrid. On Thursday evening, a communication regarding the conclusions of the study also appeared on the HM Hospitales website.
