Two students at NSW universities have been diagnosed with coronavirus over the weekend.
It comes as the number of coronavirus cases in NSW jumped by 22 over 24 hours, taking the total number of infected people in the state to 134.
The University of Sydney on Sunday said a student was diagnosed with the virus on the weekend and is one of the previously announced cases.
"The student reported feeling ill, was tested for COVID-19 and is currently in hospital, recovering and doing well", a statement from the university said.
"NSW Health and the University of Sydney have identified around 80 people who were close contacts with the student while on campus, who have been asked to self-isolate for 14 days."
A student at the University of NSW has also tested positive to the virus.
"NSW Health has advised us that the student was not contagious while on campus," a statement from a UNSW spokeswoman said on Sunday night.
"The student immediately went into self-isolation in line with health guidelines.
"UNSW staff have spoken with the student and we extend our best wishes for a speedy recovery."
The university's highest priority is the health and safety of students and staff, and it is working with NSW Health to provide updates as the situation evolves, the spokeswoman said.
Six locations on the University of Sydney's campus are being "intensively cleaned" on Sunday, according to NSW Health guidelines, the statement from the University of Sydney says.
"The current advice is that the rest of campus can continue to operate as normal," the statement.
Since the virus emerged, the university has been "closely monitoring the situation, liaising with other universities and taking advice from the federal government and NSW Health," the statement said.
"Preventative measures undertaken on campus include increased frequency of cleaning; increased signage regarding hygiene practices and installation of hand sanitiser units across the college."
