There have been no new community virus cases in Queensland, a day after two people tested positive, including a teenage boy on the Gold Coast.

Authorities were on alert after Tuesday’s cases, having confirmed the 17-year old was a household contact of a woman who recently travelled from NSW.

On Wednesday, chief health officer Jeannette Young described the result was “excellent news” and said she was “fairly comfortable” given the level of testing and limited exposure recent cases had in the community.

She said the 17-year-old was likely infected after a family member visited from northern NSW and stayed with him for three days.

The second case on Tuesday, a woman in her 30s who was in home quarantine after travelling from Melbourne, was deemed lower risk.

Meanwhile, Dr Young is pleading with unvaccinated Queenslanders to get their coronavirus jabs as soon as possible so they are protected when borders reopen on December 17.

“This is our window to get fully vaccinated so please, anyone that hasn’t had their first dose, you need to have it this week,” she said.

More than 75 per cent of eligible Queenslanders have had their first jab, and over 61 per cent are fully vaccinated.

The state had one new case in hotel quarantine.
