Australia’s Crossroads Hotel virus case highlighted the importance of diagnosing people really quickly: Official

SYDNEY, Jul 16, 2020, News.com.au. The coronavirus in NSW is spreading at a “very fast” rate and some people may have passed on the virus as quickly as one day after being infected. So far 19 people who visited Sydney’s Crossroads Hotel in Casula have got the coronavirus, and another 25 were infected through being close contacts of positive cases or going to the Planet Fitness gym, where another positive case worked out, News.com.au reported.

In less than two weeks, the virus has also spread to at least two “tertiary” cases — people who got the virus from the contact of a contact.

NSW Chief Health Officer Dr Kerry Chant said the tertiary cases highlighted the importance of diagnosing people really quickly.

“I think what’s been interesting is we’ve seen some acquisition with has been very short,” she told reporters on Wednesday, explaining that the incubation period for the disease was normally between one and 14 days.

“So people have developed the symptoms more towards the one day period than the 14,” she said.

“It gives you very little time for the contact traces because you’ve got to get your case diagnosed, and then you’ve got to lock down those contacts … I think it just highlights the speed.”

Sydneysiders were first warned of the potential Crossroads cluster on Friday and in less than a week, it has now been linked to more than 40 cases.

Authorities revealed this week that a Melbourne man who travelled to Sydney on June 30 was likely ‘patient zero’. This man had gone to the pub for a party on July 3 with work colleagues, some of whom were also likely infected.

A week later authorities identified the pub as a potential hotspot of infection after two coronavirus cases both reported they had been there.

“My message to you in the community would be, if you’ve got a sore throat today, don’t wait for two days to get it diagnosed,” Dr Chant said. “Work with us, go get tested on day one because every day you can give us allows us to stop that spread.”

‘HE DIDN’T THINK HE WAS UNWELL’

While some people may be surprised at how easily the coronavirus was spread among pub patrons, Professor Peter Collignon of the Australian National University, said it fits with how the virus operates.

“Most outbreaks in Australia, such as in nursing homes, have begun with people with mild illness going to work,” he said.

Authorities said the Melbourne man didn’t think he was particularly unwell at the time or that he was sick with COVID-19.

But Prof Collignon said people who had mild symptoms were probably the most likely to spread the disease.

In the days before the group headed to the pub, the virus was transmitted to the man’s colleagues, who then likely helped spread it more widely at the venue, including to a staff member.

While it is possible for the virus to be spread through surfaces, Prof Collignon said it was probably less about infected beer glasses and more about close contact.

“The biggest risk is being in someone’s face,” he said.

The virus is mostly spread through droplets that spray when people talk, sneeze or cough.

This is one of the reasons pubs have been identified as higher risk venues because people often speak more loudly to be heard over the music, which sprays droplets further.

People also tend stand close together and mingle with others, which is why authorities have restricted venues to seated patrons only.

“It makes sense that staff got infected, and they were then likely a vehicle to spread it to others because they were in close proximity,” Prof Collignon said.
