The increase in public health research in recent decades has seen a rapid increase in the number of articles and journals. As such, many public health journals have emerged with a specialized focus, such as in the area of policy (e.g. "Journal of Public Health Policy"), a specific region or country of the world (e.g. "Asia-Pacific Journal of Public Health", "Pan American Journal of Public Health" or "Eastern Mediterranean Health Journal"), a specific intervention/practice area (e.g. "Cancer Epidemiology, Biomarkers & Prevention"), or other particular focus (e.g. "Human Resources for Health").
