HALABE-CHEREM, José; SALADO-BURBANO, Jorge C.  y  NELLEN-HUMMEL, Haiko. Pleasant parosmia with regard to own stool after SARS-CoV-2 infection. Gac. Méd. Méx [online]. 2021, vol.157, n.6, pp.657-659.  Epub 13-Dic-2021. ISSN 2696-1288.

Coronavirus disease 2019 (COVID-19) has had a significant global impact due to the millions of deaths it has caused secondary to respiratory failure. However, the disease has also been associated with a wide array of manifestations in other organ systems. Among them, the presence of anosmia, which occurs in up to half the patients, has become a new sign of alarm to suspect the infection. Although up to 90% of affected patients will experience an improvement of their olfactory alterations within a month after the infection, the variety and severity of olfactory disturbances clearly cannot be summarized by the dichotomy of having anosmia or not. Parosmias are a type of olfactory dysfunction characterized by altered perception of odors, which can reflect both damage at some level of the olfactory tract, as well as the possibility of reversibility of said damage. The present manuscript describes possible olfactory disturbances associated with COVID-19, their pathophysiology, and potential clinical significance.
