“…Currently, the problem persists without plainly efficient tools to evaluate results and chart new directions [18]. In this context, Google Trends (GT) methodology has been used as a public interest proxy in health-related phenomena, identifying trends and patterns of accesses to various conditions in different circumstances [19][20][21][22][23][24][25].…”

“Janeiro Roxo” (Purple January) is a Brazilian campaign to raise awareness about leprosy and its early symptoms. The negative influence of the COVID-19 pandemic on institutional campaigns was especially relevant for the control of leprosy, if considered its status of neglected disease by the media. Google Trends (GT) is a free tool that tracks accesses to given terms on Google. Using GT we studied (i) impact of “Janeiro Roxo” in public interest on leprosy in the last 5 years; (ii) public interest during and after COVID-19 pandemic; (iii) patterns of public interest in self-identification of leprosy signs. Methods: GT tracking follows the popularity of topics in time range in “Relative Search Volume” (RSV) – proxies of public interest in a particular subject on a scale from 0 to 100. We selected “HANSENÍASE” (HAN) and “HANSENÍASE SINTOMAS” (leprosy symptoms) (H.SIN) to estimate public interest in leprosy and “self-diagnosis” during 261 weeks (August 2018 to 2023). Polynomial trend lines estimate trends over the period. Weekly RSV, monthly and annual means were compared using Analysis of Variance (ANOVA). Results: In 261 weeks: higher RSV to “HANSENÍASE” (HAN) compared to “HANSENÍASE SINTOMAS” (H.SIN); highest Monthly Means (MM) in January months (2019 to 2023) for both HAN and H.SIN. Pandemic effect in “Janeiro Roxo”: decrease in January MM 2021 compared to 2020 (24% to HAN, 25% to H.SIN). Both HAN/H.SIN reached pre-pandemic levels in January 2022/2023. Breakpoints (points of abrupt change which influences trend lines) in the 26th week (February 2019); in the 55th and 213th week (September 2019 and 2022). Trend line (HAN): upward curve between 33rd-45th week (April to June 2019); pandemic downward trend between 120th-136th week (December 2020 to March 2021); upward trend curve between 220th-240th week (November 2022 to March 2023). Conclusion: “Janeiro Roxo” and in-person activities, among other media stimuli, have a relevant impact in terms of public interest in leprosy, even after their interruption due to pandemic. Considering their impacts on national searches, regional campaigns should be considered very successful. RSV to HAN may be due to “reactive searches” motivated by transient stimuli from campaigns, in an ephemeral and impersonal way. “Proactive searches” to H.SIN may be associated to those interested - in a personal way - in early symptoms and self-diagnosis. Internet-based campaign evaluation programs could be useful in integrating vulnerable regions and exposing their needs for assistance services.

“…Coronavirus disease has arisen as a severe pandemic, which has resulted in substantial economic and social damage around the world. However, progress in the field of artificial intelligence (AI), cloud technology and the network of physical objects known as ‘Internet of Things’ offer a unique possibility to better medical care [ 1 , 2 ]. China, where COVID-19 was originally identified during the latter months of 2019, used successfully technology in its healthcare management systems to tackle the widespread occurrence of the disease and maintain daily life as usual [3] .…”
