One crucial strategy to avoid the dissemination of fake news is providing evidence-based information to the general public by liable organizations and institutions like WHO, OPAS, national health authorities, and academic societies. 3 Linked to the previous action is the creation of health content that is accessible for laypeople, increasing the collaboration of journalists and scientists tominimize errors in communication. 6 Finally, all physicians and healthcare providers should always elicit corrective information when confronting fake news. This strategy is proved to be useful, and the repetition of corrections also appears to be successful for reducing the effect of misinformation. 6 Applying multiple checks with social media information, detecting and avoiding information growth, and recognizing profit‑related motivation is vital for managing fake medical information. 2 As in the well-succeeded anti-smoking strategy, the government participation is essential in the fight against fake news. Combating false information must be seen not only as a momentary action, but also as a continuous effort. Thus, creating regulatory support, implementing educational actions and paying special attention to children and young adults are essential. 18 In summary, we are engaged in a new and never imagined situation as the COVID-19 pandemic is spreading. Fake news can lead to particularly serious health events. All scientists, physicians, healthcare collaborators must work together to fight fake medical misinformation. This fight must not be lost. 205 Mesquita et al. Infodemia, fake news and medicine: science and the quest fort ruth Int J Cardiovasc Sci. 2020; 33(3):203-205 Editorial
