Teach by routine, not scolding. Hand hygiene and cough etiquette work best when they become everyday habits at home, school, clinic, and public places.

What are hand hygiene and cough etiquette?

Hand hygiene and cough etiquette reduce spread of diarrhoeal and respiratory infections. They cannot eliminate infection risk, but they are simple and powerful when practised consistently.

When to use extra hygiene precautions

  • Before eating or feeding a child.
  • After toilet use, diaper changes, coughing, sneezing, or nose wiping.
  • After returning from school, playground, clinic, or public transport.
  • When someone at home has fever, cough, vomiting, or diarrhoea.

Practical home steps

  • Wash hands with soap and water, especially when visibly dirty.
  • Use alcohol-based hand rub when soap and water are not available and hands are not visibly soiled; supervise young children.
  • Cover coughs and sneezes with an elbow or tissue, then discard the tissue safely.
  • Clean frequently touched surfaces during illness.
  • Keep rooms well ventilated and keep febrile children home from school when advised.

Red flags / when to seek medical review

Seek medical care if an illness includes:
  • Fast breathing, dehydration, persistent vomiting, blood in stool, blue lips, seizure, or unusual drowsiness.
  • Exposure to infection in a higher-risk child, such as an infant, immunocompromised child, or child with chronic disease.
  • Outbreak in school or family with rapidly spreading illness.
  • Symptoms worsening despite home hygiene measures.

Important facts for parents

  • Masks, hand hygiene, ventilation, and staying home when febrile can work together.
  • Antibacterial soaps are not usually necessary for routine home use.
  • Hand hygiene helps reduce but cannot eliminate infection risk.
  • Children learn best from repeated, calm routines.
