A RISE in gastro cases in Leeton and Griffith has prompted the Murrumbidgee Local Health District to issue a warning.
The MLHD has urged parents and carers to keep young children at home if they are sick amid the rise in gastro cases.
Director of public health Tracey Oakman said the warning comes after notifications of several outbreaks of gastroenteritis at childcare centres and an increase in number of gastro presentations to emergency at Griffith Base Hospital.
Ms Oakman said gastro was often spread by direct contact with an infected person.
Viral gastroenteritis is usually caused by norovirus or rotavirus.

"It spreads easily between people if they haven't carefully washed their hands after using the toilet or before handling food," she said.
"The best defence is to wash your hands thoroughly with soap and running water for at least 10 seconds before handling and eating food, and always wash your hands after using the toilet, changing nappies or assisting someone who has diarrhoea or vomiting.
"Infants or children in childcare or school who develop vomiting or diarrhoea should stay at home for at least 48 hours after their symptoms have stopped."
People whose work involves handling food or looking after children, the elderly or patients, should not return to work until 48 hours after symptoms have stopped to avoid spread of infection. Anyone not involved in these occupations should stay home for at least 24 hours.
They can take up to three days to develop and usually last between one or two days, sometimes longer.
The main treatment for viral gastroenteritis is to rest and drink plenty of fluids.
Most people recover without complications, however gastro can be serious for infants, people with suppressed immune systems and the elderly.
Anyone recovering from gastroenteritis should avoid visiting hospitals and aged care facilities to avoid spreading the infection to those most vulnerable.
