"It's really, really important that people follow (the rules) because I genuinely don't know how many cases are out there," Dr Young said.
"The Delta variant has taken over from the previous variants so I suspect it's the Delta variant."
The results of genomic tests will be available tomorrow and may also reveal how the man came to be infected.
It's the second positive case recorded since a man tested positive to the Delta variant on Tuesday.
"He maybe got it from the reef pilot, he's maybe got it from someone else who's come through Cairns," Dr Young said.
"Anyone who's been in Cairns should be particularly cautious and if they have the slightest symptoms they should go and get tested."
Queensland Health is now increasing its testing capacity in the Cairns region.

Dr Young said Queensland Health will be contacting all of the close contacts.
"Brothers (Leagues Club) has a very good check-in process so we'll be able to track the people who were there," she said.
"If you're one of those close contacts, we'll find you."
The advice for anyone who's eligible and is still not vaccinated, is to book in for a jab as soon as possible.
