Toxicity on Social Media During the 2022 Mpox Public Health Emergency: Quantitative Study of Topical and Network Dynamics

Relationships, or user interactions, in social networks are often used to facilitate understanding of information diffusion in infodemiology [61]. We focused on 2 types of relationships on Twitter: mentions and retweets. A mention (ie, @username) is a tweet that quotes another user’s name in the text. The user who is mentioned will receive a notification from Twitter. A retweet is a reposting of a tweet that starts with “RT @username” [62].

US Public Interest in Merkel Cell Carcinoma Following Jimmy Buffett’s Death and Implications for Continued Health Advocacy: Infodemiology Study of Google Trends

Infodemiology—the study of the “distribution and determinants of information across electronic platforms”—provides valuable insights into health information–seeking behavior [2]. Infodemiology research often relies on data from sources such as Google Trends, which aggregates and anonymizes search data from Google’s search engine. Unlike traditional data collection methods, Google Trends offers real-time data that can be stratified by geographical region and time period.
