The Scientific World Journal, [s. l.], v. 2025, 2025. DOI: 10.1155/tswj/9104904. Disponível em: https://onlinelibrary.wiley.com/doi/10.1155/tswj/9104904. Acesso em: 9 mar. 2026.2356-6140e- 1537-744Xhttps://repositorio.bc.ufg.br//handle/ri/30021BSL-3 laboratories are fundamental for the safe handling of infectious microorganisms that require high-containment measures. Through a literature review, this work was aimed at highlighting the importance of these laboratories in supporting research and public health responses, especially during health emergencies. The review presents an overview of the global distribution of BSL-3 facilities, the impacts of the COVID-19 pandemic on laboratory investments, and future perspectives on their role in national development. It was observed that the pandemic exposed limitations in laboratory capacity, leading many countries to operate in suboptimal environments, underscoring the need for strict biosafety standards and preparedness infrastructure. This review also identifies disparities in global BSL-3 capacity—particularly in low- and middle-income countries—and examines the Brazilian context, where the absence of a unified regulatory framework hinders progress. By synthesizing international trends and Brazil’s recent initiatives, including the development of its first BSL-4 laboratory, this work contributes to understanding the challenges and opportunities for strengthening biosafety infrastructure in support of equitable pandemic preparedness.engAcesso Restritohttp://creativecommons.org/licenses/by-nc-nd/4.0/BiosafetyBSL-3 laboratoriesCOVID-19Health surveillancePandemicPublic healthArtigo10.1155/tswj/9104904
