The most common way infection is transmitted from one person to another is direct contact transmission , such as touching, close physical contact, or contact with contaminated surfaces that another person then touches and brings to their mouth, nose, or eyes.

Quick Scoop: Core Idea

In everyday life, most person‑to‑person infections spread when:

  • One person’s skin, secretions, or infected area touches another person.
  • Or a person touches a contaminated surface (like a door handle) and then their face (eyes, nose, mouth), allowing germs to enter the body.

Health guidance for schools and childcare settings specifically notes that direct contact spread is the most common route of cross‑infection from one person to another. This includes things like skin infections (impetigo, scabies), head lice, and many other common community infections.

Other Modes (But Less “Everyday Common”)

For context, infections can also spread by:

  • Droplets/air : Coughing, sneezing, talking at close range can spread germs through the air.
  • Faecal‑oral route : Microscopic traces of faeces reaching the mouth via unwashed hands, food, or water.
  • Blood and body fluids : Needles, sexual contact, or contact of infected blood/fluids with broken skin or mucous membranes.

These are important, but routine public‑health descriptions of “cross‑infection from one person to another” still highlight direct contact as the most frequent everyday route.

Practical Takeaway

To cut down the most common type of transmission:

  • Wash hands regularly with soap and water, especially after the bathroom and before eating.
  • Avoid touching eyes, nose, and mouth with unwashed hands.
  • Clean frequently touched surfaces like door handles, phones, and countertops.

In simple terms: the hands and the things people touch are the main highway for infections to travel between people.
