COVID-19 and damage to the olfactory system causing anosmia

ABSTRACT

Objective: To list studies that show the relationship of long-term damage to the sense of smell in adult patients with COVID-19 (coronovirus disease), in order to facilitate access to information on the management of this sequel and thus address the problem. COVID-19, caused by SARS-CoV-2, emerged in the East Asian region and became a pandemic causing the death of millions of individuals. Fever, dyspnea, cough, arthralgia, myalgia, headache, rhinorrhea and diarrhea are the most prevalent symptoms, in addition to olfactory and taste changes, which commonly cause anosmia and dysgeusia. This literature review aims to list the relationships between long-term damage to smell in patients with Covid-19 and its possible treatment. Thus, we carried out a narrative review of the literature in the PUBMED database with the following keywords "smell of loss";"Covid-19";"Chronic damage". Thus, we found seven articles, and two articles were discarded, the first for relating olfaction loss by COVID-19 in children only, a rare fact in this age group. And the second, for escaping the topic.
