Iodine as a Universal Disinfectant

For many people, the first encounter with iodine happens in childhood — a scraped knee, grandma’s first aid kit, and a cotton swab leaving a brown cross or a little iodine grid “for health.” Much has changed since then: new antiseptics in convenient spray formats have appeared. Yet iodine solution still remains a symbol of reliable protection against microbes, a proven and simple method of disinfection that is relevant today — at home, on the road, and in every first aid equipment kit.

• mucous membranes (in diluted solutions).
