The epidemic of coronavirus disease 2019 (COVID-19) broke out during the peak season of influenza in China. We aimed to assess the knowledge, attitudes, and practices (KAP) of influenza among Chinese adults during this special season. A cross-sectional online questionnaire survey was performed by recruiting 4822 participants. There were 76.09% of the participants reporting that they learned more knowledge of influenza during the COVID-19 epidemic. The mean knowledge score of participants was 5.51 ± 1.55 (78.7% correct rate), and participants who received influenza vaccination in the past year scored the highest (6.06 ± 1.30, p< .001). Nearly half of the participants (49.63%) agreed the threat to the functioning of society by influenza was far less than the COVID-19. 73.04% of the participants knew influenza vaccination was the most effective way to prevent influenza infection, while 54.18% did not know the vaccination location. The proportion of participants who were willing to get vaccinated would increase from 62.53% to 85.82% if clinicians recommended the vaccination. For influenza-like illness, merely 36.11% of participants would seek medical care from the hospital, and 60.53% agreed or showed a neutral attitude toward antibiotic use for influenza treatment. Regression analyses showed that the medical profession and history of influenza vaccination were both associated with higher knowledge or attitude score and participants' use of face masks in previous seasons and their willingness to receive influenza vaccination. In conclusion, the awareness of influenza vaccination among adults in China should be reinforced and educational campaigns were warranted to increase the coverage of influenza vaccination.
