How is stomach flu transmitted?

Gastroenteritis can spread through close contact, shared food, contaminated water, or surfaces touched after using the toilet or cleaning vomit. A person may spread infection while symptoms are present, and careful hygiene remains useful after symptoms settle because germs can remain on hands and household surfaces. Viruses such as rotavirus infection are one possible cause. Nausea, diarrhoea, abdominal pain, fever, and loss of appetite may occur, but symptoms vary.

Wash hands thoroughly with soap and running water after using the toilet, changing nappies, or helping someone who is sick, and before preparing food. Clean toilet seats, taps, handles, and nearby surfaces regularly with an appropriate disinfectant. Do not share towels, cups, or utensils while someone is unwell. Wash soiled clothing and bedding separately when possible, and keep food preparation with a well person. Encourage frequent small drinks to help prevent dehydration.

Seek medical advice if a person cannot keep fluids down, passes very little urine, becomes unusually sleepy, or has signs of dehydration. Prompt assessment is also sensible for severe or worsening abdominal pain, blood in stool or vomit, a persistent fever, or symptoms in a very young child, an older adult, or someone with a long-term illness. A clinician can assess whether another cause needs attention.

Ask which cleaning products are suitable, how long to avoid preparing food for others, and whether a child or vulnerable household member needs a different plan.
