The best way to prevent gastroenteritis is to always wash your hands with soap after going to the toilet and to disinfect toilets after use and to practice good food hygiene. Make sure you have any necessary vaccinations before you travel to other countries and drink bottled water where necessary when abroad. Help to prevent spreading the infection. Hygienically dispose of, or properly clean, all soiled items such as towels or nappies if your baby is ill. Clean the toilet with disinfectant. Don't share towels and flannels. Don't prepare food for others. Stay away from work, school or college for at least 48hr after your symptoms have stopped. Children shouldn't go swimming for 2wks after the diarrhoea has stopped.
