First aid is the help that you give someone quickly after they have hurt themselves or have had an accident . It can stop a person from becoming more ill. In some cases, it can even save a person’s life.
Only someone who knows first aid well should try to treat an injured or sick person. Usually, you give first aid until a doctor or an ambulance arrives. Never try to give someone first aid unless you know what to do. The wrong actions can do more harm than good.
