Covid-19 and tobacco

Caused by a novel coronavirus (SARS-CoV-2), COVID-19 is an infectious disease that was first identified by the World Health Organization in late December 2019. There is significant range on the COVID-19 disease spectrum—from completely asymptomatic or mild infection to advanced disease progression that results in death. Much remains to be determined about the disease—and movement along its various stages—but there is strong evidence that certain populations are particularly vulnerable to adverse consequences and that certain underlying medical conditions exacerbate it. Smokers and smoking fall into these respective categories.
