A common cold is a contagious viral infection of the nose and throat that usually improves on its own within one to two weeks, although a cough may last longer. Rest, fluids and saline nose drops may ease symptoms; antibiotics do not help, and breathlessness, drowsiness, dehydration or illness in a very young baby needs prompt assessment.
- A runny or blocked nose, sneezing and watery mucus that may later become thicker or coloured.
- A scratchy throat, hoarseness, mild headache and pressure around the nose or ears.
- Drink regularly, rest as needed and gradually resume activities once fever has gone and your strength returns.
- Ventilate indoor spaces, wash hands and cough or sneeze into your elbow; keep away from vulnerable people while you are clearly ill and contagious.
- Call the same day for breathlessness, wheezing, fast or laboured breathing, persistent high fever, drowsiness, dehydration or clear deterioration after initial improvement.
- For urgent GP care outside normal opening hours, call HAP 9252. Call Ambulance 912 only for an immediately life-threatening situation.
