Everyone who participated in the successful search for missing NSW toddler Anthony "AJ" Elfalak is being urged to get tested for COVID-19.
NSW Health has requested everyone who helped in the search at the property, from emergency services to family members, volunteers and media, get tested and isolate until they receive a result.
They are also requested to get a second test within five days of the first.
This request has been made as there were people in attendance from Sydney Local Government Areas (LGAs) of concern.
There was also limited mask wearing and close proximity between team members due to the nature of the search.
Dozens of people from family members to police search and rescue, paramedics and SES were involved in the search for the toddler.
When asked about a potential positive case in Putty, NSW Chief Health Officer Dr Kerry Chant said she was not aware of it but would follow up with her team.
"Someone mentioned something. I have to confirm it. It's probably new overnight," Dr Chant said when asked about the Putty case.
"I think it's important to work through things factually. Let me get the facts first and we'll issue the public health advice in a statement. But clearly we'll do everything we can to get that information out as soon as possible."
