Public and global health examines how we protect communities from disease, manage outbreaks, and improve well-being across the world. This vital field connects diverse research on everything from infectious disease control and vaccination strategies to the social factors that shape our collective health. Because these studies often impact policy and daily life, understanding them quickly is more important than ever.

At Gist.Science, we track every new preprint published in this category on medRxiv to ensure you never miss a breakthrough. We process each submission to provide both plain-language explanations for general readers and detailed technical summaries for experts, making complex findings accessible to everyone.

Below are the latest papers in public and global health, freshly summarized from the most recent medRxiv releases.
