The strain of coronavirus wreaking havoc on South Australia has particular characteristics that are most concerning to authorities.
As the state announced it was going into a full lockdown for at least six days from midnight Wednesday in a bid to combat the latest Covid-19 wave, Chief Health Officer Professor Nicola Spurrier explained the reason for the tough move.
“This particular strain has had certain characteristics,” she said today.
“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 and 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.”
