Orange parents have been urged to keep their child at home if they're feeling unwell following a spike in viral gastroenteritis cases in recent days.
Western NSW Local Health District director of public health Priscilla Stanley said gastroenteritis was highly infectious and could spread rapidly, particularly in childcare centres.
She said symptoms - including nausea, vomiting, diarrhoea, fever, abdominal pain, headache and muscle aches - could take up to three days to develop and usually last between one or two days.
"We're seeing a few spikes in the number of cases in the Bathurst, Mudgee and Orange regions," Ms Stanley 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, as should staff members and anyone whose work involves handling food or looking after children, the elderly or patients."
Ms Stanley said the main treatment for viral gastroenteritis was to rest and drink plenty of fluids.
Most people recover without complications but gastroenteritis 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," Ms Stanley said.
"Any person living in a household affected by gastroenteritis should refrain from visiting these high-risk areas until at least 48 hours after the last person in the household has recovered."
Childcare centres should reinforce basic hygiene measures to help prevent the spread of infections.
