Abstract: Objective This study aimed to understand the trend of online public attention toward ear symptoms before and after the SARS-CoV-2 infection outbreak, use the Baidu Index to explore the correlation between SARS-CoV-2 infection case numbers and public interest in China, and investigate the potential of online data as an early warning for public health events. Methods Keywords associated with ear symptoms(“hearing impairment”“tinnitus” “hearing loss”“vertigo” “ stuffy ears”“deafness”)were extracted from the Baidu index platform. Searched volume data were compared before and after the outbreak. We used a one-way analysis of variance to analyze differences in search volume pre- and post-outbreak. Pearson correlation coefficients were calculated between the Baidu search index and the daily trend of SARS-CoV-2 cases nationwide. Results Compared to the same period in previous years(2017-2020), online searches for “hearing impairment”“tinnitus” “hearing loss” “vertigo”“deafness” significantly increased 2020-2023(all P<0.001). The Baidu search index for “hearing impairment”“hearing loss” “vertigo” “stuffy ears” “deafness” showed significant positive correlations with new SARS-CoV-2 cases(all P<0.001). Conclusion Following the SARS-CoV-2 outbreak, online public attention to ear symptoms intensified. We observed a significant positive correlation between the Baidu search index for ear symptoms and the new number of COVID-19 cases. These findings suggest that monitoring online trends in ear symptoms may hold promise for early prevention and control of SARS-CoV-2.
