*Bold indicates statistical significance. aOR, adjusted OR; ILI, influenza-like illness; NA, not applicable; OR, odds ratio; SRI, severe respiratory illness.
†Only variables found to be statistically significant (p<0.2) in univariate analysis were assessed in the multivariable model.
‡Underlying conditions defined as previously diagnosed chronic conditions including asthma, chronic lung diseases, cirrhosis or liver failure, chronic renal failure, heart failure, valvular heart disease, coronary heart disease, diabetes, burns, kwashiorkor or marasmus, nephrotic syndrome, spinal cord injury, seizure disorder, emphysema, and cancer, or history of immunosuppressive therapy or splenectomy.
§Viruses tested were influenza types A and B, adenovirus, enterovirus, rhinovirus, human metapneumovirus, respiratory syncytial virus, and parainfluenza virus types 1–3.
