The tour was originally to begin on July 30, but the pandemic delayed all tours, and England's three-test series against the West Indies next month isn't scheduled to end until July 28.
“Pakistan's itinerary will be announced in due course," the ECB said.
The 10 players and one staff member who tested positive for the virus this week are self-isolating in their homes in Pakistan, and will join the tour when they are cleared.
The players who tested negative in the first round underwent a second round of testing on June 25 in Lahore, the results of which are awaited.
"They (Pakistan team) will start a 14-day isolation period at Blackfinch New Road, Worcester before transferring to Derbyshire's The Incora County Ground on July 13 to accelerate their preparation ahead of the first Test, which will include two four-day internal warm-up matches," stated the ECB.
"All members of the tour party will have been tested prior to travel. Those who are testing positive for Covid-19 will not be permitted to travel with the advance group on Sunday," it added.
England is currently slated to face West Indies in the three-match Test series starting July 8 at the Ageas Bowl. The England vs West Indies Test series will be also part of ICC World Test Championship.
The Pakistan Cricket Board
expressed concern on Friday over the positive results from 10 of the 29 cricketers chosen for the tour. The only good news
was that none have showed symptoms, and all have time to recover.
The board met via video conference and approved a 2020-21 budget of 7.76 billion rupees (around $46 million), including for the Pakistan Super League, its premier T20 tournament.
The PCB had to suspend the PSL in March but hopes to stage the playoffs this year. Peshawar was added as a fifth venue for the 2021 tournament starting in February.
