Policy during coronavirus disease 2019 (COVID-19) pandemic: a protector for acute exacerbation of COPD (AECOPD) patients?

摘要

The novel coronavirus disease 2019 (COVID-19) was first identified in 2019 (1). COVID-19 is a respiratory and systemic illness that may progress to severe hypoxemia and acute respiratory distress syndrome, which ultimately leads to death. The global number of COVID-19 cases (as June 13, 2020) has reached 7,553,182, which has led to a global economic burden and negative impact on the entire world’s population (2). Although the outbreak of COVID-19 is relatively controlled in China, the risk factor remains.
