More than seven decades of Acta Tropica: Partnership to advance the 2030 Agenda for Sustainable Development

The inaugural issue of Acta Tropica has been published in 1944, at a time of utmost international isolation and uncertainty due to World War II. Now, more than seven decades later, Acta Tropica is a trusted outlet to communicate and disseminate scientific advances in the fields of parasitology and tropical medicine. As a scholarly, peer-reviewed journal, Acta Tropica contributes to the 2030 Agenda for Sustainable Development, particularly the Sustainable Development Goal (SDG) 3, that is "Ensure healthy lives and promote well-being for all of all ages". This article explores how Acta Tropica has evolved over time. Our analysis is based on a systematic review of keywords derived from all issues published in a specific year, arbitrarily selected at decadal snapshots (1950, 1960, 1970, 1980, 1990, 2000, 2010, and 2020). Results indicate a decrease in interdisciplinarity in favour of more specialised expertise in various fields of infectious diseases research and public health with a particular emphasis on low- and middle-income countries. Yet, by examining first and last authors' institutional affiliations and classifying countries by the Human Development Index (HDI), we find that most authors are affiliated with institutions in high- and very high-HDI countries. Over time, the mean number of authors on a paper has increased severalfold (from 1.35 in 1950 to 7.51 in 2020). Taken together, Acta Tropica has become increasingly globally anchored and contributes not only to SDG 3, but increasingly also to SDG 17, that is "Revitalize the global partnership for sustainable development".
