Most childhood illnesses are caused by viruses — colds, hand-foot-and-mouth disease, rotavirus diarrhoea and chickenpox among them. It is important for parents to know that antibiotics do not work against viruses.
What to understand
Most viral infections clear on their own within 7–10 days as the body responds. Care mainly relieves symptoms — reducing fever, replacing fluids and rest. Antibiotics are used only when a clinician confirms an added bacterial infection.
Preventing spread
- Wash hands often with soap and cover coughs and sneezes with the elbow.
- Keep cups, spoons and towels separate.
- Keep scheduled vaccinations up to date.
