Internet Health Information–Seeking Trend of Urinary Incontinence in Mainland China: Infodemiology Study

As described in previous studies [18,21], three modules on the Baidu Index platform—(1) the searching trend, (2) user demand, and (3) the demographic portrait module—enabled the analysis of search demand by examining trends in popularity, topic-related concerns, and the geodemographic features of each topic. The Baidu search index (BSI) value is the key index that numerically scales the popularity of each search keyword.

Mapping of Health Literacy and Social Panic Via Web Search Data During the COVID-19 Public Health Emergency: Infodemiological Study

Hence, this phenomenon is worthy of further attention and discussion. We obtained web search data from the Baidu Index [4].
