The recent COVID-19 mini-outbreak in the Mountains appears to have been kept under control.
There were fears earlier this month when two students from Blue Mountains Grammar tested positive as did a visitor to the Katoomba Aquatic Centre.
Then two patrons of Springwood Sports Club, who were there on Saturday, September 12, returned a positive result. They went to Lawson Oval on the following day to watch a soccer game.
The local health service said there were five cases of COVID-19 in the Blue Mountains council area at 8pm on September 20.
The last two people reported positive on September 15 and there have been no further cases since.
The recent positives were from Wentworth Falls (two), Katoomba (two), Lawson and the Hazelbrook/Linden postcode.
The senior students at Grammar (years 10, 11 and 12) went immediately to online learning after the latest notifications.
In the school's newsletter of September 18, the deputy head of the senior school, Owen Laffin, said that the campus would be closed to all students for the remainder of term three, which finishes on Friday.
"We will follow our usual timetable, which students will access via the portal. Teachers will be expecting students in Zoomed lessons and learning materials will be available via Google classroom.
"We will be marking class rolls, with teachers using presence on Zoom and completion of learning tasks to ascertain whether or not students are present."
Mr Laffin noted: "The Blue Mountains Grammar Senior School community has been its best and most impressive self this week as we transitioned rapidly to online teaching and learning. COVID-19 has had a significant impact on our lives in recent days, with many students and staff now learning and teaching in self-isolation."
This month's outbreak brings to 38 the total number of COVID-19 positives in the whole local government area since the pandemic hit earlier this year.
The first cases were recorded on March 8 and 10, in postcode 2777. Then there were 20 in March, five in April and two in May.
The next cases were in July, when a Katoomba resident and three household members were caught up in the outbreak linked to the Crossroads Hotel in Casula.
George Truman, the acting public health director for Nepean Blue Mountains Local Health District, said: "Thank you to the Blue Mountains community for continuing to come forward for a COVID-19 test. By getting tested, and following the guidelines for staying COVID-safe, everyone is doing their part to keep our community safe."
