COPD, Smoking Increase Death Risk in COVID-19 Patients, Study Says
Smokers and people with chronic obstructive pulmonary disease (COPD) are more likely to develop severe complications and die from COVID-19 infections than infected patients who do not smoke or have COPD, a recent meta-analysis shows. This research, however, suggests that the prevalence of COPD patients and smokers among those infected is low. The study, "Prevalence, Severity and Mortality associated with COPD and Smoking in patients with COVID-19: A Rapid Systematic Review and Meta-Analysis," was published in the journal PLOS One. COPD patients are believed to be highly vulnerable to infections with the new coronavirus, not only because their disease chronically affects the lungs, but also because of comorbidities such as high blood pressure or diabetes that appear to increase the risk of severe coronavirus infections. A recent pre-print (a study available before peer review) suggested that this patient group is even more likely to develop severe disease or to be admitted to intensive care units than those with high blood pressure or diabetes. To shed more light on the impact of coronavirus infections in COPD patients, researchers in the U.K. and Saud
