A woman in Medan, North Sumatra has tested positive for COVID-19 after a recent trip to Jerusalem.

The 51-year-old woman is the second confirmed case in Medan. The first patient, a doctor, passed away Tuesday.

COVID-19 response team coordinator at Adam Malik Hospital in Medan, Ade Rahmaini, said the first and second case were not connected. However, she said both patients had recent travel history to Jerusalem.

"Both have travel history to Jerusalem but in different groups," Ade said on a press conference on Thursday.

The hospital’s spokesperson, Rosario Dorothy Simanjuntak, said 11 people were being treated in isolation rooms as of Thursday.

"10 patients are COVID-19 suspects and one has tested positive for the virus," Rosario said.

North Sumatra Health Agency head Alwi Mujahid said the agency was tracing the group that went to Jerusalem with patient one.

"Patient one, a lung specialist,  had traveled to Jerusalem and Italy. He went with a group of people and we're tracking them at the moment,"Alwi told The Jakarta Post on Wednesday. (nal)
