Smoking Associated with worse COVID - 19 Symptoms and Outcomes

Prevention is key to controlling the transmission of COVID-19; stopping smoking, including the use of e-cigarettes or vapes, as well as eliminating exposure to second-hand smoke, should be high on the list of measures to prevent COVID-19 infection.


While smoking and exposure to second-hand smoke, do not cause COVID-19, they increase people’s vulnerability to infection, and may result in worse symptoms and outcomes, especially in the elderly.


Studies of the progression of COVID-19 induced pneumonia among Chinese patients, indicate higher levels of illness in patients with a history of smoking. Smokers have a weakened immune system and lowered resistance to infections relative to non-smokers. The National Council Against Smoking (NCAS) encourages smokers to stop smoking altogether, and to ensure that children are not exposed to second-hand smoke.


Other health risks associated with tobacco include various cancers, stroke, heart disease, tuberculosis and a range of respiratory diseases.


In order to help protect South Africans from infection with COVID-19 and other diseases, the NCAS calls on the Minister of Health to urgently expedite passage of the Tobacco Control Bill.
