A new study recommends mouthwash and tooth brushing to prevent pulmonary symptoms of COVID-19
The SARS-CoV2 virus first invades the upper respiratory tract, namely the nasal cavity, pharynx and larynx. Therefore, the virus will inevitably spread through saliva and in the mouth.Now, a study conducted by the University of Birmingham shows that this virus can Enter the lungs through saliva.
The oral cavity is an ideal place for viruses and bacteria to multiply, but the defenses of the human immune system and basic hygiene measures are sufficient to prevent infection. Coronavirus is no exception, it can easily multiply in the mouth. If the person suffers from plaque buildup, periodontitis or gum inflammation (usually involving immune barrier failure), this will allow the coronavirus to enter the bloodstream.

Once the coronavirus reaches the blood vessels in the gums, it will pass through the blood vessels in the neck, chest and reach the heart. The heart pumps blood, and the virus reaches the blood vessels around the lungs. This may explain why the blood vessels supplying the lungs are affected at the beginning of lung disease caused by COVID-19.
Researchers recommend that people take basic hygiene measures, such as brushing their teeth 3 times a day and using mouthwash. These simple behaviors will help maintain healthy gums and prevent the most serious cases of COVID-19.
