Prefab Hospitals, also known as modular or prefabricated hospitals, are healthcare facilities constructed off-site in a controlled factory environment and then transported to the location for assembly. 

These hospitals are designed to provide all the necessary medical services and can range from small clinics to full-scale hospital complexes. Prefab hospitals offer a quick, efficient, and cost-effective solution to meet urgent healthcare needs, such as during pandemics, natural disasters, or in underserved areas.
