Salus
Salus studies health, care, welfare, flourishing, and preservation: the practices and states of keeping human bodies and populations in a state of well-being.
Global Human Health
Population Geography · 2025
Estimated residential population in 100 × 100 metre grid cells. Yellow and green indicate greater population concentrations; blue and violet indicate lower or zero population.
Salus begins with humanity as a planetary population: unevenly distributed, biologically connected, and embedded in local environments.
This map shows where human life is concentrated before the module descends into health systems, bodies, cells, microbes, bacteria, and viruses.
Global Disease Burden
Salus treats global health as a layered field of chronic disease, infectious disease, care access, and population-scale vulnerability.

Ontology Module
Open Morbus Explorer→Morbus
Explore the detailed human disease ontology: etiology, physiological failure modes, axis matrices, and classification crosswalks.
Human Body
Salus connects the study of pathology and care back to the healthy physical structure of the person — tracing wellness and disease failures directly to the anatomical and physiological substrates of the organism.
Primary Module
Open Soma Explorer→Soma
Explore the physical substrate of human life. Soma models the healthy body as an integrated physiological machine across multiple scales of representation.
Anatomy
Bodily structures, form, and spatial relationships.
Physiology
Functions, regulatory loops, and homeostatic mechanisms.
Histology
Tissue-level fabric and cellular architecture.
