A primary school and a child care centre have closed and eight more exposure sites have emerged in the wake of positive COVID-19 cases in the Riverina.
The revelations come after Murrumbidgee Local Health District [MLHD] warned of further transmission following the detection of six new cases in Albury, Edward River and Greater Hume on Thursday.
Little Ones Early Learning in Howlong has been advised of a positive case of COVID-19 linked to the service and will not be open on Friday.
Through its Facebook page, the centre asked everyone who attended the centre on Monday and Tuesday, including parents and carers, to get tested and self-isolate "until we receive confirmation from NSW Health and Department of Education on the impact on our service".
"We'd appreciate if you could please send through your results as they are received," the centre said.
"While we cannot confirm at this stage that every child and or educator at our service has been impacted, we are taking every safety precaution while NSW Health undertakes contact tracing.
"We will provide an update as soon as we have clarification on the date of reopening."
A Jindera school has also been closed for cleaning after a student contracted coronavirus while new Border exposure sites have also been listed.

Anyone who attended those venues is considered a casual contact and must be tested for COVID-19 and self-isolate until they receive a negative result.
"You may be required to get more than one test," NSW Health advised.
Mr Moss said St John's would continue to work with NSW Health to maintain the safety and health of staff and students.
"While we recognise this may be disruptive and inconvenient for families, it is important we follow NSW Health advice and take all necessary precautions to minimise the risk of further transmission to support our community," he wrote.
