3/ wound cleaning and infection
Soap and water is the baseline for cleaning a wound. Plain water alone is not enough.
• Wash with clean soap and water, then apply antiseptic
• Cover with a clean dressing and change it when wet or dirty
• Watch for increasing redness, swelling, warmth, or fever
Most problems that get worse start with a wound that was not cleaned properly or left open.
4/ Multivitamins, fluid loss, and prescriptions
When fresh food is limited for weeks, a basic multivitamin covers the most common gaps from a narrower diet. It does not replace food. Store a few months’ supply with the kit.
Diarrhea, vomiting, and fever remove fluids quickly. Have oral rehydration salts or know how to mix a basic solution with clean water.
Prescription medications are different. If anyone in the household takes them regularly, the practical step is to talk with the primary care provider about longer fills or an extra supply while systems are still normal. That conversation is separate from stocking the over-the-counter items above.
