Intersecting pathways of pandemic emergence, tobacco control and noncommunicable diseases: a contemporary synthesis of global health determinants and policy implications

The convergence of pandemic emergence, tobacco use and noncommunicable diseases (NCDs) presents a complex public health challenge. These domains are interlinked through shared determinants such as globalization, environmental degradation, socioeconomic inequities and weak health systems. Understanding these intersections is crucial for integrated policy responses in a post-COVID-19 world. This review synthesizes current global evidence on the interconnectedness of pandemics, tobacco control and NCDs, highlighting the implications for global health governance and policy innovation. A systematic search was conducted across PubMed, Scopus, Web of Science and WHO databases using MeSH terms such as "pandemics", "tobacco use", "noncommunicable diseases" and "global health policy". Studies published between 2000 and 2024 were included, with quality assessed using the MMAT-2018 tool. The review identifies four core intersections tobacco use exacerbates vulnerability to infectious disease severity and NCD comorbidities, NCD prevalence increases pandemic morbidity and mortality, tobacco control efforts were disrupted during global health emergencies; and pandemic policies overlooked integrated NCD and tobacco risk factors. Findings emphasize that siloed responses undermine resilience and health equity. Integrated global health policies must address the syndemic nature of pandemics, tobacco use and NCDs. Strengthening primary care, enforcing tobacco control and embedding NCD strategies in pandemic preparedness are essential. Multisectoral governance, health equity frameworks and sustainable development approaches must guide future policies.
