Illness Management

Part of First Aid

Without pharmacies or hospitals, treating common diseases with available resources becomes a core survival skill.

In a post-collapse world, the diseases that kill are not exotic. They are the same ones that killed billions throughout human history before modern medicine: diarrheal diseases, respiratory infections, wound infections, and waterborne parasites. Most of these are preventable with sanitation and clean water (see Water Purification and Sanitation and Hygiene). When prevention fails, your treatment options are limited but not nonexistent.

Diarrheal Diseases

The number one killer in any survival scenario. Cholera, dysentery, and common gastroenteritis all cause death through dehydration — the disease itself is often survivable if you can replace the fluids lost.

Recognition

Symptom	Mild (Gastroenteritis)	Moderate (Dysentery)	Severe (Cholera-like)
Stool frequency	3-5 times/day	6-15 times/day	Near continuous
Stool appearance	Watery, no blood	Blood and/or mucus	”Rice water” — clear fluid
Fever	Low or none	Moderate to high	Often absent
Dehydration	Mild	Moderate	Severe, rapid
Abdominal pain	Cramping	Severe cramping	Minimal (painless purging)

Treatment

1. Fluid replacement is the treatment. See Dehydration Treatment for oral rehydration solution preparation
2. Give small, frequent sips — large volumes at once trigger vomiting
3. Continue feeding if the patient can eat. Bland foods: rice, boiled potatoes, plain bread, bananas
4. Isolate the patient from others. Diarrheal diseases spread through fecal contamination
5. All feces must be buried at least 30 meters from any water source and 60 cm deep
6. Anyone caring for the patient must wash hands thoroughly with soap or ash and water after every contact

Warning

Bloody diarrhea with high fever may indicate bacterial dysentery (Shigella, Salmonella) or amoebic dysentery. These are more dangerous than viral gastroenteritis and can cause intestinal perforation. Without antibiotics, aggressive hydration and rest are your only tools.

Respiratory Infections

Pneumonia, bronchitis, and influenza — respiratory infections spread rapidly in group living situations and are the second-largest cause of death after diarrheal disease in resource-poor settings.

Recognition

Symptom	Common Cold	Bronchitis	Pneumonia
Fever	Low/none	Moderate	High (39°C+)
Cough	Dry or mild	Productive (mucus)	Productive, may be rusty/bloody
Breathing	Normal	Mild difficulty	Rapid, labored, painful
Chest pain	None	Mild	Sharp, worse on breathing
Duration	5-10 days	1-3 weeks	Weeks without treatment
Danger level	Low	Moderate	High — can be fatal

Treatment

For all respiratory infections:

• Rest — the body fights infection during rest
• Fluids — at least 2-3 liters per day. Warm fluids help loosen mucus
• Steam inhalation — boil water, drape a cloth over the patient’s head, have them breathe the steam for 10-15 minutes. Add thyme, eucalyptus, or pine needles if available (these contain volatile antimicrobial compounds)
• Elevate the head and chest during sleep — lying flat worsens congestion and cough
• Isolate the patient if possible — respiratory diseases spread through cough droplets

For pneumonia specifically:

• Monitor breathing rate. Normal adult: 12-20 breaths per minute. Over 30 per minute is a danger sign
• Keep the patient sitting upright or propped at a 45-degree angle
• If available, make a garlic-honey preparation: crush 4-5 cloves of garlic into 3 tablespoons of honey. Give 1 teaspoon every 4 hours. Both have documented antimicrobial properties
• Watch for blue lips or fingertips (cyanosis) — this indicates severely low oxygen and is a critical emergency with limited treatment options outside modern medicine

Fever Management

Fever is a symptom, not a disease. It is the body’s defense mechanism — most pathogens replicate less efficiently at elevated temperatures. Treat the underlying cause, not the fever itself, unless the fever becomes dangerously high.

When to Treat Fever

• Below 38.5°C (101.3°F): Generally beneficial. Keep the patient comfortable, ensure hydration. Do not actively cool.
• 38.5-40°C (101.3-104°F): Monitor closely. Use cooling measures if the patient is uncomfortable. Ensure aggressive hydration.
• Above 40°C (104°F): Dangerous. Active cooling is necessary. Brain damage becomes a risk above 41°C.

Cooling Methods

1. Tepid sponging: Wring out cloths in lukewarm (not cold) water and place on the forehead, armpits, groin, and neck — these are areas where major blood vessels run close to the skin
2. Remove excess clothing and blankets — the instinct is to pile on blankets during chills, but this traps heat
3. Fan the patient or move to a well-ventilated area
4. Cool fluids: Small, frequent sips of cool (not ice-cold) water

Warning

Never use cold water immersion or ice packs on a feverish patient. Rapid cooling causes shivering, which actually raises core temperature, and can trigger dangerous cardiac rhythms. Use lukewarm water only.

Natural Antipyretics

• Willow bark tea: The original aspirin. Boil a thumb-sized piece of inner bark in 500 ml of water for 15 minutes. Strain and drink. Contains salicin, which converts to salicylic acid in the body. Dose: one cup every 4-6 hours. Do not give to children under 16 (risk of Reye’s syndrome equivalent) or patients with stomach ulcers.
• Elderflower tea: Steep dried or fresh elderflowers in boiled water for 10 minutes. Promotes sweating, which aids cooling. Safe for children.
• Meadowsweet tea: Another natural salicylate source. Steep the dried flowers in boiled water. Gentler on the stomach than willow bark.

Wound Infections (Progressed)

When a wound infection escapes local control despite antiseptic treatment (see Antiseptic Sources).

Signs of Systemic Infection (Sepsis)

• Fever above 38.5°C or temperature below 36°C (paradoxically, late-stage sepsis causes low temperature)
• Heart rate above 100 beats per minute
• Breathing rate above 20 per minute
• Confusion, disorientation
• Red streaks extending from the wound toward the heart

Treatment

1. Open the wound and drain any pus collection. This requires a clean, sharp blade — cut along the axis of the limb through the most swollen, fluctuant area. Let pus drain completely. Do not squeeze.
2. Irrigate aggressively with boiled saline (see Antiseptic Sources)
3. Pack the wound open — do not close it. Stuff loosely with honey-soaked clean cloth
4. Apply garlic poultice to the surrounding skin
5. Force fluids — at least 3 liters per day
6. Keep the patient resting with the infected area elevated

Without antibiotics, systemic sepsis has a high mortality rate. These measures give the patient’s immune system the best possible chance, but they are not a substitute for modern medicine.

Parasitic Infections

Common in environments with contaminated water and inadequate sanitation.

Intestinal Worms

Signs: Abdominal pain, visible worms in stool, bloating, weight loss despite adequate food, anal itching (pinworms).

Treatment options:

• Pumpkin seeds: Eat 30-50 raw seeds on an empty stomach. Contains cucurbitin, which paralyzes some species of roundworms and tapeworms. Repeat daily for 3 days.
• Raw garlic: Eat 2-3 cloves daily on an empty stomach for 1 week. Allicin has antiparasitic properties.
• Papaya seeds (if available): Chew 1 tablespoon of seeds on an empty stomach. Contains proteolytic enzymes that dissolve worm cuticles.
• Wormwood tea (Artemisia absinthium): Steep 1 teaspoon of dried leaves in boiled water for 10 minutes. Drink on an empty stomach once daily for 5 days. Do not exceed this dose — wormwood is mildly toxic in large quantities.

Prevention

• Always boil drinking water
• Cook all meat thoroughly — internal temperature above 70°C kills most parasites
• Wash hands before eating and after defecation
• Wear footwear — hookworms enter through bare feet
• Do not use human feces as fertilizer without composting at high temperature for at least 6 months

Quarantine Principles

When someone in your group develops a potentially contagious illness:

1. Isolate the patient in a separate shelter or room, at least 2 meters from others
2. Designate one caregiver. That person should minimize contact with the rest of the group
3. Ventilate the sick room — airflow reduces airborne pathogen concentration
4. Separate all eating utensils, bedding, and clothing. Wash with boiling water
5. Wash hands with soap (or wood ash and water) after every patient contact
6. Monitor the rest of the group for symptoms for 14 days after the patient recovers

Key Takeaways

• Diarrheal diseases kill through dehydration — the treatment is fluid replacement, not stopping the diarrhea
• Respiratory infections require rest, hydration, steam inhalation, and isolation; monitor breathing rate to distinguish pneumonia from lesser infections
• Fever below 38.5°C is generally beneficial; above 40°C is dangerous and requires active cooling with lukewarm (not cold) water
• Willow bark tea is a genuine natural antipyretic containing salicin, the precursor to aspirin
• Wound infections showing red streaks, fever, or confusion indicate systemic sepsis — drain, irrigate, pack open with honey, and force fluids
