The recovery time for new crown taste and smell is about a week for short periods of time and may take about two months for longer periods of time, depending on the severity of the condition. If you receive treatment at the early stage of infection, the virus is usually less harmful to the human body, only damaging the nasal and oral mucosa and other parts of the body, not involving the nerves, so you can return to normal in a week or so. If the virus has been infected for a long time and the condition is serious, the virus may damage localized nerve tissues, and depending on the severity of the nerve damage, the recovery time is usually two months. After the patient loses the sense of smell and taste due to the new crown, blood tests and other tests can be performed to clarify the cause, and then the right medicine can be prescribed according to the type of cause. If the sense of taste and smell can not be recovered, the patient should go to the hospital in time to find out the cause to avoid delaying the condition.
