If it's diagnosed and treated early, the infection is more likely to be mild and can be treated at home with antibiotics.
If you have severe symptoms, such as persistent vomiting, severe diarrhoea or a swollen stomach, you will probably be admitted to hospital.
If your symptoms get worse, see your healthcare provider as soon as possible. They may give you a different type of antibiotic.
You need to stay off work so you don’t spread the infection. You can go back to work as soon as you feel better unless you work with food, young children, elderly people or people with poor health. If you do, you will need to do another stool sample to be sure the bacteria have gone.
Some people have a relapse about a week after they finish their antibiotics. If you start to feel sick again, see your doctor as soon as possible.
If you don’t get treatment straight away, you can develop complications, eg, internal bleeding or splitting of your digestive system, meningitis, inflammation or infection of other organs, or even death.
