It is possible for the sequelae of the new coronavirus to cause the patient to eat lemons without taste, because the new coronavirus infection may lead to transient loss of the sense of taste. Some patients with neocoronavirus have a diminished sense of smell and taste, or even loss of taste, and after discharge from the hospital, they still have a diminished sense of taste and smell, or even loss of taste, which can usually be gradually recovered. Neocoronavirus is usually transmitted through respiratory droplets, aerosols and direct contact. Once infected with neocoronavirus, the taste buds will be violated by the virus, causing loss of taste, and the sense of taste will be gradually restored to normal after the organism has cleared the neocoronavirus. Therefore, after being infected with Neocoronavirus, patients are advised to actively seek treatment to avoid the development of severe disease and to minimize the after-effects.
