Why did Qatar enforce quarantine rules for six Asian countries?

Vaccinated travellers from six Asian countries need to quarantine for two or 10 days.

Doha, Qatar – Qatar’s decision to enforce mandatory quarantine for vaccinated travellers coming from six Asian countries was a result of an “increased number of positive cases” among those arrivals, health authorities have told Al Jazeera. Starting from August 2, all vaccinated travellers from India, Pakistan, Bangladesh, Nepal, Sri Lanka and the Philippines are subjected to a two-day hotel quarantine if they received an approved vaccine in Qatar or 10 days if vaccinated elsewhere, the Ministry of Public Health (MoPH) announced on July 29. The announcement, and different requirements based on where the vaccine was received, caused outrage on social media, with people questioning the need to quarantine for additional days despite getting the same vaccine.
