Four new cases of the novel coronavirus were confirmed in Ontario on Sunday.
Each of the patients were diagnosed at hospitals in the Greater Toronto Area, health officials said.
“As a result of the co-ordinated efforts of our health care and public health system, all individuals who have tested positive have been quickly assessed and isolated,” the province’s ministry of health said in a statement.
All of the new cases are tied to travel. Health officials did not comment on the patients’ conditions but said they are all currently in self-isolation.
One patient, a man in his 50s who is a Toronto resident temporarily living in Vaughan, Ont., is the brother of a Toronto man who also travelled to Iran and was later diagnosed with COVID-19.
