Hafeez tweeted a photograph of himself taken with a woman on the golf course near Pakistan's onsite hotel at the Ageas Bowl, where the second Test starts on Thursday.
"Met an inspirational young lady today (Wednesday) morning at golf course. She is 90+ & living her life healthy & happily. Good healthy routine," he wrote.
But with the photograph clearly showing Hafeez and the unnamed individual were within the two-metre guideline for social distancing, the Pakistan Cricket Board (PCB) announced later on Wednesday the all-rounder would be isolated.
"This morning, Mohammad Hafeez went to a golf course, which is adjacent to the team hotel and part of the bio-secure bubble," said a PCB statement.
"During the golf round, he was photographed with a member of the public, which he subsequently posted on his social media account.
"As it was evident from the photograph that Hafeez had breached the two-metre social distancing protocol and following a consultation process with the team doctor, the team management has decided to isolate him until he returns a negative COVID-19 test.
"Hafeez underwent the COVID-19 test late on Wednesday afternoon and the result is expected at some stage on Thursday."
This series is being played under special protocols because of the global coronavirus outbreak, with the PCB statement adding the decision to isolate Hafeez had been taken "for his and, the safety and security of everyone around him."
"The team management believes it was an inadvertent mistake, but a good reminder for everyone on the importance of following the bio-secure protocols, which have been designed for the health and safety of everyone involved in the series."
The PCB said the England and Wales Cricket Board had been informed of their action regarding Hafeez.
While players from both teams have been permitted to use the golf course at the Ageas Bowl, they have been advised to avoid interaction with anyone outside the 'bubble' as the course remains open to the public.
The 39-year-old Hafeez is not a member of Pakistan's Test squad, but is on the tour ahead of the three-match Twenty20 series starting on Aug.28.
An opening batsman and off-spinner, Hafeez tested positive for COVID-19 before leaving Pakistan.
Hafeez then had a private test of his own, which produced a negative result.
He then returned two more negative tests, with the PCB then allowing him to travel to England.
Pakistan and England cricket teams on Wednesday observed a one-minute silence before the start of the first Test at the Old Trafford as mark of respect for all those affected due to the COVID-19 pandemic.
"Fitness has been an important part of our strategy as a team since I took on the role of head coach last September and we have seen the benefits in the two Tests so far," Misbah wrote in a column for the Pakistan Cricket Board's website.
Pakistan Test captain Azhar Ali on Thursday lauded bowlers ahead of their series against England and stated he is lucky to have young pacers like Shaheen Afridi and Naseem Shah in the line-up.
