Inpatients with influenza during 2017–2018 smoked more frequently (19.7% vs. 6.9%, p < 0.05) (Table 1), especially among the 14–59 years category (Table 3), and experienced shortness of breath (dyspnea) more frequently (17.3% vs. 5.9%, p < 0.05), and were significantly higher in alanine aminotransferase (ALT) (30.9% vs. 21.4%, p < 0.05) and creatine kinase (CK) (21.3% vs. 10.4%, p < 0.01). This evidence concerns the gene GPT and influenza.
