‘Dodged a bullet’: Expert explains why WA may have escaped COVID spread

Amid questions of how Western Australia could have escaped further community spread, an infectious disease expert has dispelled suggestions the security guard dubbed Case 903 might have been a false positive. Senior Australian infectious disease experts are also at odds over the effectiveness or benefit of WA’s short, sharp lockdown. A security guard who worked at one of Perth’s quarantine hotels tested positive to the highly infectious UK strain of COVID-19 on Saturday and dozens of locations around the city have been established as possible exposure sites. But extensive testing over the past three days has not produced any further cases of community spread. Professor Adrian Esterman from the University of South Australia told 6PR’s Gareth Parker the reason might be that Case 903 was one of those people who was not very infectious.
