Scientist Suggest Infectious CCP Virus Mutations Could be the Cause of Hotel Quarantine Leaks Infectious disease experts believe that the highly infectious variants of the CCP virus could be the cause of quarantine leaks across Australia after Victoria reported three new cases connected to their quarantine program in the past week. The latest case, a woman in her 50s tested positive for the CCP (Chinese Communist Party) virus, commonly known as the novel coronavirus, on Sunday after she worked at the Holiday Inn near the Melbourne airport. “If these breaches are these more highly contagious strains, then there is a question about whether the sort of prevention should be ramped up even more,” Prof. Malcolm Sim, a government adviser, and president of the Australasian Faculty of Occupational and Environmental Medicine, said on Monday.
