The nurses had treated the patient before he had been confirmed to have been infected
Taiwan reported a five-person jump in new cases of the coronavirus on Saturday, including four people who had contact with another infected patient in a hospital and one person returning from the Middle East, bringing Taiwan's total to 39.
The government's Central Epidemic Command Centre said a cleaner and three nurses were the four staff who had been infected at the hospital, which was treating another coronavirus case.
The nurses had treated the patient before he had been confirmed to have been infected, it added.
The fifth new case is a woman in her 60s who went on a tour to Egypt and Dubai and who returned to Taiwan on Feb. 21 having begun feeling unwell while in Egypt, the center said.
She is most likely to have been infected while overseas, and the government is tracking down others who were on the same tour, it added.
Taiwan has reported one death from the coronavirus, while 9 patients have recovered and been released from hospital.
The government on Thursday raised its epidemic response level to the highest, and postponed a major religious event scheduled for next month.
