The soaring brain drain in the healthcare sector constitutes a pressing and formidable threat to public health in third-world countries. The increasing interconnectedness of the world has facilitated sharing of ideas and collaborations across borders, benefiting the global population. However, this has also led to the migration of skilled healthcare professionals from low-income countries to more developed nations. This is due to push factors such as the lack of proper healthcare infrastructure, low income, poor working conditions, and limited career opportunities which push healthcare workers to seek better prospects in more developed countries. Pull factors such as better remuneration, working conditions, and career advancement entice them to migrate to these countries. Consequently, the delivery of adequate healthcare services becomes severely compromised, exacerbating existing challenges in achieving public health goals. The impact of this phenomenon extends beyond mere workforce loss. It stifles local education, hinders advancements in medical research, and undermines the overall capacity to combat prevalent health issues. Urgent action is imperative to address this silent crisis. By prioritizing the improvement of domestic healthcare systems, offering competitive incentives for healthcare professionals, and fostering international collaboration, we can effectively mitigate brain drain and strengthen the foundation of public health in third-world countries. This Paper aims to identify the drivers behind brain drain, highlight implications for public health and proffer potential solutions and actionable plans to address this growing concern.
