Background: In the US, African Americans and Latinos are overrepresented among cases of and deaths from COVID-19.  Minority communities may be more susceptible to severe forms of COVID-19 because of existing disparities in underlying conditions. Sinopulmonary conditions (asthma, chronic obstructive pulmonary disease, obstructive sleep apnea, chronic sinusitis, and allergic rhinitis), which are exacerbated by respiratory viruses, have not been well studied in COVID-19.

Objective: Examine the effect of sinopulmonary conditions on COVID-19 risk and severity and explore the early relationship between COVID-19 and healthcare utilization among patients with sinopulmonary conditions.
