In low and middle-income countries, which contribute to over 85 percent of all COPD cases worldwide, "non-smoking COPD may be responsible for up to 60-70 percent of cases," noted the report's authors.

Since smoking is an avoidable risk factor for poor prognosis in COVID-19 infection, a national effort at smoking cessation, bolstering deaddiction services and supporting individuals in their efforts to quit tobacco use is an intervention that may be necessary to reduce demand for scarce resources - PPEs, ICU capacity, and ventilators.

"I think the reasonable assumption is that because of those injuries to local defenses and the information we have from other respiratory infections, people who smoke will be at more risk for more serious COVID-19 infection and more likely to get even critical disease and have to be hospitalized.". Compared to other study designs, the BCS is considered a high-quality study because of its randomized trial design, little missing data, clear smoking status definitions, and laboratory-confirmed data. A new study led by UC Davis Comprehensive Cancer Center researchers shows that current smokers have a 12% increased risk of a laboratory-confirmed viral infection and a 48% increased risk of being diagnosed with respiratory illnesses.
