All 107 Covid-19 tests conducted on Zimbabwe and Pakistan players, support staff and match officials have returned negative ahead of the limited-overs series starting later this week, the Pakistan Cricket Board said on Tuesday.
The tests were conducted Monday as part of the PCB's Covid-19 protocols for the bilateral series.
All players, officials and staff have moved into a hub in a five-star hotel in Islamabad, the PCB said, and "are now allowed to interact with each other and move freely within the bio-secure bubble."
Both teams will start training Tuesday at the Pindi Cricket Stadium, which will host the three ODIs and three Twenty20 Internationals.
The series begins with one-dayer on Friday. Lahore was originally scheduled to host the Twenty20 series but those matches were shifted because of expected smog next month.
