Health & Sanitation

Part of Phase 3: Small Group

Health & Sanitation covers post-collapse medicine at community scale: a working pharmacy, surgery without a hospital, disease transmission and quarantine, public sanitation, and the veterinary side of a mixed herd. Two exact-duplicate labels, two “Contraindications” and two “Dosage Calculation,” are fixed below. Surgery and Public Health both chain off Herbal Medicine and Pharmacy and Apothecary, which itself requires herbal medicine and alcohol distillation.

Pharmacy and Apothecary, Dispensary Setup, Pharmacy Setup, Storage Organization, Documentation Format, Building a Pharmacopoeia, and Key Medicines cover running an actual pharmacy. A tincture steeped 2-6 weeks in 40%+ alcohol keeps for 3-5 years, and mislabeled concentrations can cause a tenfold overdose, which is exactly what organized storage and labeling exist to prevent. A community pharmacopoeia works like the USP, fixing what each preparation must contain and at what strength.

Dosage Calculation (Herbal), Dosage Calculation (Pharmacy), Age Adjustments, Weight-Based Dosing, Contraindications (Herbal Medicine), Vaccine Contraindications, Therapeutic Window, and Dilution and Dosing cover getting a dose right. A standard adult dose can be lethal, not just ineffective, for an infant or elderly patient, and a drug dosed at 500 mg for a 70 kg adult scales to about 143 mg for a 20 kg child. “Natural” doesn’t mean safe: digitalis is a life-saving heart medicine at a low dose and a lethal poison just above it.

Surgery, Anesthesia, Ether Production, Herbal Anesthetics, Local Anesthesia, Abdominal Surgery, Appendectomy Basics, Hernia Repair, Wound Surgery, Fracture Repair, Cast Making, Reduction Techniques, and Post-Operative Care cover the largest cluster: operating without a hospital. Surgeons once raced to amputate a limb in under ninety seconds because patients went into shock from pain alone, until the 1840s changed what surgery could try, and diethyl ether stayed the standard general anesthetic for a century after 1846. More patients die of post-operative complications than of the operation itself.

Aspirin from Willow, Pain Relief, Opiate Management, and Quinine Extraction cover plant-derived medicines. Willow bark and meadowsweet carry the same salicylic acid later purified into aspirin, and quinine, extracted from cinchona bark since the 1600s, was the antimalarial until synthetic drugs replaced it.

Airborne, Contact, Vector-Borne, Waterborne, and Transmission Routes cover how disease actually spreads. Bubonic plague, spread by fleas, killed one-third of Europe’s population in the 14th century, and more people have died of waterborne disease than of every war in history combined.

Disease Surveillance, Contact Tracing, Quarantine Duration, Quarantine Systems, and Isolation Facilities cover catching an outbreak before it spreads. A cholera case caught at one household is still containable; the same outbreak found at 40 households has already outrun what any community can handle, and quarantine length is set by a disease’s longest incubation period, not the average — cholera needs 5 days, typhoid and measles 21.

Public Health, Sanitation Infrastructure, Sewage Systems, Water Treatment, and Health Education cover the settlement-wide fixes. Municipal water treatment is estimated to have cut typhoid mortality by over 90% in the cities that adopted it, and teaching a mother to boil water before giving it to a sick child costs nothing and prevents more disease than almost any other single measure.

Abscess Drainage, Common Diseases, Digestive Disorders, Respiratory Illness, Vital Signs, Quarantine Protocols, and Prevention cover the veterinary side. Bloat can kill a cow or goat within hours, and bovine respiratory disease is the leading cause of death in young livestock worldwide — nearly every disease outbreak in livestock history began with one untested arrival.

Patient Monitoring and Risks and Monitoring close the loop on vaccination: observation in the first 30 minutes and through the next 1-72 hours, with a system for reporting delayed reactions.

Pharmacy and Apothecary

Running an actual pharmacy: storage, records, and the reference that fixes what each preparation must contain.

Dosing and Safety

Getting a dose right by age, weight, and condition, where medicine and poison are often a matter of amount.

Surgery

Operating without a hospital, from anesthesia through the specific procedure and the recovery after.

Plant-Derived Medicines

What a plant can substitute for a pharmaceutical analgesic or antimalarial.

Disease Transmission

How a disease actually moves from one person to the next.

Surveillance and Quarantine

Catching an outbreak early, and the isolation infrastructure that stops it spreading.

Public Health Infrastructure

The settlement-wide fixes that save more lives than surgery or medicine ever will.

Veterinary Health

Recognizing and treating the diseases that account for most livestock deaths.

Vaccination Monitoring

Watching a vaccinated patient for the reaction window that actually matters.
