Gargling is an easy way to reduce infection and transmission of viruses. Antiseptic mouthwashes, like Listerine, effectively reduce oro- and nasopharyngeal (mouth, throat and nose) viral load and inactivate coronaviruses.
The nose, throat and salivary glands are major sites of virus replication and transmission during early stages of coronavirus infection, as well as other respiratory viruses and bacteria. Targeting these areas with mouthwashes and nasal rinses can help prevent progression and reduce transmission of the disease.
While the vaccines aim to prevent viruses from replicating in the lungs, they do not prevent viruses from replicating in the nose, mouth and pharynx, which has a different type of mucosa than the lungs and this area is the first area to be infected.
The easiest thing we can do is to gargle daily for prevention of transmission of viruses and bacteria. Alternatively, gargling can be applied after exposure to someone who is sick or potential exposure after flying or being in a crowded place. This can be helpful for all people regardless of vaccination history.
