‘NO TIME TO WAIT’ – Terrifying new Covid strain emerges that spreads FIVE TIMES quicker making contact tracing impossible

The US Sun:

A NEW strain of coronavirus has been detected in South Australia that it is thought could spread up to five times quicker than previous strains.

Spurrier said that the length of one generation is currently around only three days.

The news is part of the reason the state has entered a strict six-day lockdown despite only 36 active cases of the virus having been identified.

The lockdown came into force at midnight on Wednesday as authorities moved to stop a second wave taking hold.

Discussing the decision, Professor Nicola Spurrier, chief health officer for South Australia, said: “This particular strain has had certain characteristics. It has a very, very short incubation period. 

“That means when somebody gets exposed, it is taking 24 hours or even less for that person to become infectious to others.”

People contracting earlier strains of Covid could become infectious as early as day one or late as day 14, but the average was around five to six days.

Spurrier continued: “The other characteristic of the cases we have seen so far is they have had minimal symptoms and sometimes no symptoms but have been able to pass it to other people.”

She went on to explain that the speed at which the current strain is able to spread meant that contact tracing in the state had already identified at least five “generations” of infections.

In epidemiology, a person is said to be in the first generation of infections if they were infected by the patient zero.

Anyone infected by a person in the first generation is in the second generation, and so on.

Spurrier said that the length of one generation is currently around only three days.

“At the moment in SA we have done contact tracing to the fourth generation but the fifth generation is out there in our community and at the moment we are contact tracing to get on to that generation,” she said.

There is concern that the virus is already spreading through the western suburbs of state capital Adelaide after a number of outbreaks were identified.

‘RIGHT TO BE CAUTIOUS’

Professor Allen Cheng, acting chief health officer in the neighbouring state of Victoria, said it was possible the apparent speed of the spread was accounted for by improved testing, the Guardian reported.

He said it could be that new cases were being identified early in the incubation period, before people developed symptoms, but added that authorities in South Australia were right to be cautious.
