Coronavirus | Mild COVID-19 patients: This is the most serious sequel that affects them

According to the World Health Organization (WHO), 80% of patients who recover from COVID-19 do not need hospital treatment, however, one in six of them may develop a serious condition as a sequel: difficulty breathing (dyspnea) and loss of voice quality (dysphonia).

Any respiratory consequences that the virus may have will have an effect on the voice of patients, but how does this happen and how does it affect the voice? During the onset of the disease and, in some cases, for months, a person who suffered from COVID-19 your breathing capacity and voice quality may be limited.

Among the main symptoms are loss of voice quality, respiratory fatigue, odynophagia (pain when speaking) and a feeling of pressure in the chest or fatigue from any movement, no matter how minimal it may be.

Also, according to the article published in The Conversation, the voice quality may also be affected, so Hoarseness, a harsh or dry voice, laryngeal and chest pain, a feeling of stiff throat, neck pain and a decrease in the tone scale may occur. But why does COVID-19 affect the voice?

Being voiced air produced by the speech apparatus and amplified by the resonators, the sound is created when the vocal cords vibrate from the exhaled air that passes through them. Consequently, if there is shortness of breath, there is no voice.

Thus, if the respiratory capacity is affected, the same will happen with the quality of the voice. Also, when you have COVID-19 you can experience prolonged and excessive coughing spells. This, added to the force that is exerted on the vocal folds to allow a strong expulsion of air, causes the vocal cords to swell, become rigid and less flexible, so the voice tends to change.
