Since Sunday 2 February, a total of 17,093 people have been assessed at Sydney International Airport. A total of 64 were sent for testing.

This includes testing conducted yesterday where 263 arrivals from mainland China were assessed at Sydney International Airport. None was sent for testing.

This morning, passengers and crew from the Maasdam cruise ship were assessed after it docked in Sydney Harbour because they came from international waters. No one had symptoms suggestive of novel coronavirus or recent travel from China, and none required novel coronavirus testing.

Of the four confirmed cases, all patients have been discharged, a 53 year old male, a 35 year old male, a 21 year old female and a 43 year old male.

No new patients were confirmed overnight.

NB: The figures refer to people who are in NSW and have been investigated for, or have been diagnosed with novel coronavirus.

We will not be disclosing the hospital locations of patients under investigation for privacy reasons.
