A small percentage of patients temporarily lose their sense of taste after recovering from neocoronavirus, which usually recovers with the development of time. New crown, the new coronavirus, is characterized by fever, dry cough and malaise after infection. Some patients may have nasal congestion, runny nose, sore throat, decreased or lost sense of smell and taste, conjunctivitis, myalgia and diarrhea. The degree of recovery from hyposmia or loss of taste varies from person to person after presentation, with some patients recovering within a few weeks, while others may persist for a month and beyond. Some researchers have now analyzed the effects of Neoguana virus on the human olfactory system and detected persistent SARS-CoV-2 virus particles in the olfactory mucosa of Neoguana patients presenting with persistent olfactory loss, suggesting that long-term recurrent olfactory loss in Neoguana patients may be due to persistent viral infection. The recovery of the sense of taste is inconclusive at this time, and the report is only for a subset of patients and needs to be confirmed by further studies, as well as supported by additional clinical data.
