Using natural language processing (NLP), we applied the BosonNLP sentiment dictionary to assign emotional values (EVs) to each comment. Latent Dirichlet Allocation model was used to identify key public concerns, and Spearman correlation analysis was conducted to examine relationships between engagement metrics (comments, likes, responses) and EVs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The 40 popular posts received 5,107 comments, 144,940 likes, and 7,358 responses, respectively.

Users with the most comments came from Guangdong, Shanghai, Beijing, Zhejiang, and Chongqing. The public was most concerned about attitudes and the transmission mode of the mpox. Sentiment analysis showed that the comments were mostly negative (76.13%). The EVs of the negative comments were 32.31 times higher than those of the positive comments. The numbers of comments, likes, and responses were all significantly associated with EVs (p\u2009&lt;\u20090.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Public sentiment following the first imported mpox case in mainland China was predominantly negative and highly concentrated within the first four hours.
