Karachi: An official source in the Pakistan Cricket Board said the New Zealand health authorities confirmed that three people have returned positive while one result is pending.
“But the main thing is these three positive results are under investigation to find out whether they are historical cases or new infections,” the source said.
Former captain Sarfaraz Ahmed and pacer Muhammad Abbas are understood to be among the historical cases.
The source said earlier when six members tested positive, two turned out to be historical cases and they were allowed back to the team floor where they are in isolation while the remaining four are on a separate floor in quarantine.
“It is determined that historical cases are not suspected of passing on infection to others as they have built up required anti-bodies but new cases are treated differently,” he said.
The New Zealand health officials in an official release said that swabs were taken on Day 6 yesterday from the 46 members of the Pakistan cricket squad in Christchurch who until then have returned negative results for COVID-19.
Of those, 42 have subsequently returned a further negative test result. Three are under investigation to determine whether they are historical cases, and one test result is pending.
The visiting team is not allowed to train until the Canterbury DHB medical officer of health determines they are satisfied that any training activities are unlikely to transmit COVID-19.
