Pakistan confirmed two more cases of coronavirus on Saturday, bringing the total number of positive cases to four since Wednesday when the first two cases were reported in the country.

“We have received reports of two more positive cases of coronavirus, one has been reported in Sindh province, (the) other in federal areas,” Zafar Mirza, Pakistan’s health minister, told a news conference.

The minister did not say in which cities the new cases were reported, asking media to respect the patients’ privacy. He said the two people in the earlier reported cases were doing well and one was about to be discharged from hospital.

Sindh information minister Murtaza Wahab told Reuters one of the new cases was in Karachi, the country’s economic hub, bringing the number recorded there to two.
