The Twitter hashtags # ACSCC20 and # CNCirugia2020 were studied to determine tweets, retweets, users and impressions. The data on the accounts with the greatest influence and the historical evolution of the congresses between 2015 and 2020 were analyzed. We used the symplur software to collect and analyze the data. Between 2015 and 2017 there was a consistent increase in the number of tweets, participants and impressions. Between 2018 and 2020, the ACS maintains the number of impressions with the fewest number of tweets. However, the CNC continues to grow and achieves its best metrics in 2020. We found statistically significant differences between the most prolific accounts of the ACSCC versus the CNC (P Virtual congresses generate a global impact through the use of Twitter for the dissemination of knowledge. In the present 2020, the growth of the impact on social networks has been proportionally greater in the CNC than in the ACSCC. However, the ACS virtual congress generated the greatest impact on social networks measured by the number of users, tweets and impressions between 2015 and 2020.enAmerican College of Surgeons Clinical CongressAsociación Española de CirujanosCOVID-19Congreso Nacional de CirugíaImpresionesImpressionsRedes socialesSARS-CoV-2Social networkTwitterresearch article34082894open access10.1016/j.ciresp.2021.04.0222173-5077PMC8165562https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8165562https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8165562/pdf
