Knowing what kind of response to expect from the Chinese government, people react with chaos when news of fresh cases nearby breaks out. On Sunday night Shanghai Pudong airport “descended into chaos” after two cargo handlers there tested positive for Covid-19. Hundreds of flights were cancelled.
Authorities set up a testing site at the airport and ordered all airport cargo employees to be tested. Although passengers reportedly understood and feared that everyone was going to be tested and quarantined. That may have been the initial plan, scaled back as riots were feared.
