Dear Editor, SARS-CoV-2 has been spreading rapidly across the world as well as the number of fake news on social media regarding harmful or non-harmful treatments which are ineffective for treating COVID-19. In Brazil, the first case of COVID-19 was confirmed on February 26, 2020 and until March 20, 2020 at least 970 cases and seven deaths have been reported. The fear and uncertainty have led people to consume and share mistrust and misinformation on the Internet. Since the first confirmed case in Brazil, fake news about the effectiveness of an ether and chloroform blend known as “lança perfume” or “loló” were spread on social media. Nowadays, the ecosystem of big data has provided valuable information about online health-related behaviour and new patterns among population groups using social media data. Google Trends may act as an efficient real time surveillance system by monitoring hit searches of specific health issues leading to reliable and meaningful indicators to track health information demand and supply trends. We used Google Trends to assess recent search activity (from February 25 to March 20, 2020) on the novel coronavirus in Brazil and the popularity of related search terms. Related searches for coronavirus revealed a high level of interest (a breakout over 5000%) on the information about the use of an ether and chloroform blend in treating COVID-19, especially in the North and Northeast regions which are recognized as the poorest regions in the country.
