MELBOURNE : When a large coronavirus cluster was rumored to have begun among gay men partying in Seoul’s most cosmopolitan nightlife district, city health officials opted for anonymity.Anonymous testing was provided in clinics to counter the discrimination and stigma gay men in South Korea often experience -- which would have created a barrier authorities worried could hamper case-finding.
In response, more than 40,000 nightclub visitors and their contacts were tested, helping to arrest a nationwide outbreak that spread to at least 246 people, researchers said in a report last week.The screening approach and contact tracing were supported by information gleaned from location data from mobile phones, credit card payment history, public.
