A muffled voice is not necessarily a result of infection with the new coronavirus; muffled voices are relatively rare in people infected with the new coronavirus. There are many reasons for a muffled voice. Usually pharyngitis and laryngitis of the upper respiratory tract can cause a muffled voice.
1. After infection with the new coronavirus, the typical symptoms of fever, malaise, dry cough, nasal congestion, runny nose, or sore throat may occur in some people, but rarely the symptoms of mute voice.
2. If you have not traveled to a medium-high risk area and have not been in contact with a patient with a new crown, consider pharyngitis or laryngitis caused by other bacteria or viruses, which may lead to the symptoms of a muffled voice.
It is recommended to go to the hospital to identify the cause of the disease. If you suspect that you may be infected with the new coronavirus, you should complete nucleic acid testing as soon as possible to rule out the possibility of new coronavirus infection.
