• Abstract: How do conspiracy theory communities in Latin America and the Caribbean structure, articulate, and sustain the dissemination of disinformation about autism? To answer this question, this research investigates the structuring, articulation, and promotion of autism-related disinformation in conspiracy theory communities in Latin America and the Caribbean. By analyzing publications from 1,659 Telegram communities over ten years (2015 - 2025) and examining more than 58 million pieces of shared content from approximately 5.3 million users, this study explores how false narratives about autism are promoted, including unfounded claims about its causes and promises of miraculous cures. The adopted methodology combines network analysis, time series analysis, thematic clustering, and content analysis, enabling the identification of dissemination patterns, key influencers, and interconnections with other conspiracy theories. Among the key findings, Brazilian communities stand out as the leading producers and distributors of these narratives in the region, accounting for 46% of the analyzed content. Additionally, there has been an exponential 15,000% (x151) increase in the volume of autism-related disinformation since the COVID-19 pandemic in Latin America and the Caribbean, highlighting the correlation between health crises and the rise of conspiracy beliefs. The research also reveals that false cures, such as chlorine dioxide (CDS), ozone therapy, and extreme diets, are widely promoted within these communities and commercially exploited, often preying on desperate families in exchange for money. By addressing the research question, this study aims to contribute to the understanding of the disinformation ecosystem and proposes critical reflections on how to confront these harmful narratives.

  We conduct a comprehensive analysis of four months of rumor-related online discussion during COVID-19 on Weibo, a Chinese microblogging site. Results suggest that the dread (cause fear) type of health rumors provoked significantly more discussions and lasted longer than the wish (raise hope) type. We show the efficacy of debunking in suppressing rumor discussions, which is time-sensitive and varies across rumor types and debunkers.

  The outbreak of the novel coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been continuously affecting human lives and communities around the world. We used multiple data sources, i.e., PubMed and ArXiv, and built several machine learning models to characterize the landscape of current COVID-19 research. Our findings confirm the types of research available in PubMed and ArXiv differ significantly, with the former exhibiting greater diversity in terms of COVID-19 related issues.
