Impact of chronic airway inflammatory diseases on COVID‑19

ABSTRACT

The COVID‑19 pandemic causes an overwhelming number of hospitalization and deaths with a significant socioeconomic impact. Several studies have linked the severity of COVID‑19 to risk factors such as age, male, hypertension, diabetes, obesity, cardiovascular disease, liver and kidney disease, cancer, and pregnancy. The association between chronic obstructive pulmonary disease (COPD) and asthma, the most common chronic airway inflammatory diseases in the population, and SARS‑CoV‑2 infection is not yet clear. This article will review the comorbidity rates of COPD and asthma in COVID‑19 patients, their effects on COVID‑19, and the possible mechanisms, in order to provide scientific data for clinical practice. © 2022 Editorial Board of Medical Journal of Wuhan University.
