• Organisers have lowered the Ct value to 35 from 40, which means those recovering from Covid-19 are less likely to test positive on arrival in Beijing
• ‘At what level of Ct does somebody start being infectious or stop being infectious is not absolutely clear,’ IOC medical chief Brian McCloskey says
