In late March, the government shut down all non-essential services and announced a general holiday to contain the transmission of the virus, first reported in China in December last year.
But health experts expressed concerns over the decision to allow people to travel to their home districts during the Eid holidays, fearing that it will worsen the coronavirus situation in the coming days.
