There is no compelling evidence to suggest that patients with PD are more likely to contract COVID-19 or that they are at elevated risk for worse COVID-19 outcomes [113]. However, PD is associated with decreased respiratory function, which might contribute to respiratory distress in any number of infections, including COVID-19 [114]. Furthermore, PD is comorbid with a number of disorders, including cerebrovascular disease, heart failure, and coronary artery disease, any of which would elevate risk of worse outcomes if COVID-19 was contracted [22].
