Hunt on for 'patient zero' who spread coronavirus globally from SingaporeSINGAPORE/SEOUL/LONDON (Reuters) - As lion dancers snaked between conference room tables laden with plastic bottles, pens, notebooks and laptops, some staff from British gas analytics firm Servomex snapped photos of the performance meant to bring good luck and fortune. Three weeks later, global health authorities are still scrambling to work out who carried the disease into the mundane meeting of a firm selling gas meters, which then spread to five countries from South Korea to Spain, infecting over a dozen people. Experts say finding this so-called "patient zero" is critical for tracing all those potentially exposed to infection and containing the outbreak, but as time passes, the harder it becomes.
