ALVAREZ ARIAS, Priscila e CAIRA CHUQUINEYRA, Brenda. Trends of Internet search about chlorine dioxide in eight Latin American countries during the COVID-19 pandemic. Rev. cuba. inf. cienc. salud [online]. 2022, vol.33 Epub 30-Jun-2022. ISSN 2307-2113.
Infodemiology and infovigilance are computer methods for the analysis and monitoring of Internet data, and allow awareness of situations and creation of health policies. This study aimed to analyze the search trends for chlorine dioxide and equivalent terms on the Internet (chlorine dioxide solution, CDS; miracle mineral solution, MMS), in relation to COVID-19 morbidity and mortality in eight Latin American countries. Google Trends was used for this purpose; the period reviewed was from March 1st to November 25th 2020. The 7-day moving average for relative search volume (VRB), morbidity and mortality rate were calculated. For the association of quantitative variables, the Spearman correlation coefficient was used with a significance level p < 0.05. The country with the highest search interest was Bolivia; the one with the least interest, Brazil. The analysis of the VRB with the morbidity and mortality rate was different between countries. The maximum VRB peaks of Colombia and Chile, in April, and of Mexico, Ecuador and Bolivia, in July, coincided with the issuance of health alerts on chlorine dioxide. Most showed a moderate and low significant correlation between VRB and the number of confirmed cases and daily deaths from COVID-19. The behavior of the searches, differentiated between countries, could indicate greater interest in the topic of chlorine dioxide during the pandemic; this would be explained by the dissemination of health alerts from international, regional and local health agencies.
