ARE SMOKERS AND VAPERS AT HIGHER RISK OF COVID-19 INFECTION?

Are Smokers and Vapers at Higher Risk of COVID-19 Infection? 

Risk of Hand-to-Mouth Virus Transmission 
Smoking and vaping involve frequent contact between fingers and lips, which increases the possibility of transmission of virus from hand to mouth. In some cases, smoking and vaping involve the sharing of cigarette and e-cigarette products and mouth pieces, which could facilitate the transmission of COVID-19 in public and social settings. 
Risk from Reduced Lung Capacity 
COVID-19 is a lung illness that can cause patients to experience mild to severe lung complications. Pre-existing lung disease or reduced lung capacity may greatly increase risk of serious illness. Activities like smoking and vaping that reduce the ability of the body to use oxygen properly could put patients at higher risk of COVID-19 and other serious lung conditions. More research is needed and new evidence is emerging.
