Limitations
VIRUS, COMPLICATIONS, INFLUENZA
The limitations of the study are as follows: there was no etiological virus typing and antiviral drug sensitivity detection. Moreover, children, the elderly, and patients with serious pre-existing medical conditions who tend to be more susceptible to influenza and complications due to low resistance were excluded. Additionally, the study was conducted in only one province due to regional limitations, and thus the results cannot be generalized. We hope to expand the study scale and number of cases in the future to further explore the effect of early treatment with arbidol tablets on the outcome, prognosis, and spread of suspected influenza cases in China.
