Sharing vaping devices raises questions about COVID-19 transmission. This article provides clear, science-backed information on the potential for SARS-CoV-2 spread through sharing personal items like vapes.
How COVID-19 Spreads
SARS-CoV-2, the virus that causes COVID-19, primarily spreads through respiratory droplets and aerosols expelled by an infected person. These particles are released during activities like breathing, speaking, coughing, or sneezing. Larger droplets fall quickly, while smaller aerosols can remain suspended in the air and travel further, especially in enclosed spaces.
Infection most commonly occurs by inhaling these virus-laden particles. People can also become infected if droplets land directly on their eyes, nose, or mouth. An infected person can spread the virus even without symptoms, or before symptoms appear.
Indirect transmission can occur through contact with contaminated surfaces, or fomites. If respiratory droplets land on a surface, and another individual touches it before touching their eyes, nose, or mouth, transmission is possible. This route is less frequent than direct respiratory spread.
The mouth and saliva play a role in virus transmission. Research shows SARS-CoV-2 can infect cells within the mouth and salivary glands, making saliva a potential source of infectious viral particles.
The Specific Risks of Sharing Vaping Devices
Sharing vaping devices poses risks for COVID-19 transmission. The primary risk comes from direct mouthpiece contact with the user’s mouth, transferring saliva and respiratory secretions. Since saliva can contain infectious viral particles, sharing a device directly exposes users to these secretions.
Vaping involves frequent hand-to-mouth contact, which can contribute to transmission. If hands are contaminated from surfaces or the face, repeatedly bringing the device to the mouth increases the likelihood of self-infection or transferring the virus to the device. The virus can persist on surfaces, making contaminated devices a source of infection.
When a person exhales during vaping, they release respiratory particles, including droplets and aerosols, into the air. While the device does not generate infectious aerosols, the user’s exhaled breath can carry the virus. Sharing a vape often occurs in close proximity, increasing exposure to these potentially virus-laden particles.
The social nature of sharing vaping devices amplifies the risk. These environments increase close contact between individuals, a primary factor for COVID-19 spread. This combination of close proximity and shared, mouth-contacting objects creates an environment for viral transmission.
Protecting Yourself and Others
To minimize COVID-19 transmission, especially in social settings, avoid sharing personal items. This includes vaping devices, which contact the mouth and can harbor viral particles. Maintaining personal hygiene is important for preventing viral spread.
Wash hands regularly with soap and water for at least 20 seconds, or use an alcohol-based hand sanitizer with at least 60% alcohol. Avoid touching your eyes, nose, and mouth with unwashed hands, as this can transfer the virus into your body.
Maintain physical distance from others, especially in crowded or poorly ventilated indoor environments, to reduce inhaling respiratory droplets or aerosols. If experiencing COVID-19 symptoms or testing positive, stay home to prevent further transmission.
Cover coughs and sneezes with a tissue or your elbow to contain respiratory droplets. Staying up to date with COVID-19 vaccinations provides protection against severe illness and can reduce the risk of infection and transmission.
