ABSTRACT
The syphilis and COVID-19 pandemics have marked a turning point in the history of mankind. The aim of this review is to analyze what two pandemics caused by different diseases have in common. It is a scoping review made up of papers covering everything related to syphilis and COVID-19. The dialectical structural model of care (DSMC) is applied, focusing on three thematic plots that explain the historical and current context of the topic addressed. To this end, we compiled information from books, journals, and databases such as Cochrane, National Library of Spain, PubMed/Medline, Scielo, and Google Scholar. Syphilis is a bacterial disease transmitted sexually. COVID-19 is a viral infection transmitted by droplets. Despite their similarities and differences, both have triggered pandemics that have claimed the lives of thousands of people. Both still exist as active diseases. The origin of both remains a scientific enigma;many human and material resources have been devoted to tackling these two infections, and a wide range of drugs have been developed to combat them. © 2023 by the authors.
