Otolaryngologist Vladimir Zaitsev said that the cause of the musty smell in people who suffered from Covid-19 may be rhinitis.
“Covid-19 disease can result in rhinitis, which in turn leads to maxillary sinusitis,” Zaitsev added.
And the Russian expert continued: “When inflammation appears there, the mucous membrane swells not only in the sinuses, but also in the fistula. There the openings open and this unpleasant smell intensifies, because the inflammation of the sinuses increases more and more every day.”
The doctor noted that the bad smell disappears with cleaning the openings. Zaitsev recommended to go to the clinic when such symptoms appear.
