Traveling to Pakistan on Emirates from US (recently tested positive)

Please point me to the correct post if it was recently asked;

Problem/Scenario:

• recently tested positive
• fully vaccinated
• planning to take Emirates to Karachi
• Pakistan wants a PCR test

as per CDC FAQs...

People can continue to test positive for up to 90 days after a COVID-19 diagnosis without being infectious to others. For this reason, travelers who have recovered from COVID-19 in the past 90 days do not need to get tested before or after travel.

Question: what if I get a positive results (before going to Pakistan) - or Positive result on the way back...

• will Emirates stop me from boarding?
• will Pakistan stop me from entering?
• will Dubai be a problem during transit

Emirates' website has been ambiguous and they have an automated message on their helpline and they're not answering the phone - can someone help?
