a
Types of lung disease included chronic obstructive pulmonary disease (chronic bronchitis or emphysema), treated tuberculosis, interstitial lung disease, cystic fibrosis, asthma, bronchiectasis, or other.
b
Samples sizes for this analysis were comorbid lung disease (n = 119), immunocompromised (n = 90), older adults (n = 109), and other adults (n = 59).
