When to seek help
Adults

Respiratory Hygiene
Covering your cough and sneeze can stop the spread of germs that make people sick.
- DO use a tissue and place it immediately in the bin. Wash your hands or use a hand sanitiser.
- DO cough or sneeze into your upper sleeve.
- DON’T cough or sneeze into your hands. You’ll end up spreading germs to everything you touch.
