Sumary of Sydney’s Covid test: what will it take to bring the case numbers down?:
- As Sydney approaches four weeks in lockdown, the number of Covid cases infectious in the community – which experts say needs to reach close to zero before restrictions can be eased – remains stubbornly high.
- “It’s a key number that we are very keen to bring down, and a key indicator of risk to the community at any one time, so it’s an important number,” Dr Jeremy McAnulty, the executive director of NSW Health’s Covid-19 public health response branch, says.
- The infectious period for Covid-19 is 14 days – calculated from two days before the onset of symptoms, or, if someone has no symptoms, from two days before they tested positive.
- ”On Thursday the NSW premier Gladys Berejiklian said during the daily press conference: “Unfortunately we get recurring cases of people who have symptoms and turn up to work thinking they’re not infectious … then we have people who think they have no symptoms and visit people outside their household and spread it.
- But a professor of public health and adviser to the World Health Organization (WHO), Mary-Louise McLaws, says NSW needs clearer and tighter mask-wearing rules that “remove the luxury of interpretation” and take into account Delta spreads more easily, as seen at outdoor sporting events in Victoria.
- He is hopeful the impact of the lockdown will start to be reflected through lower case numbers in coming days, so long as people adhere to public health measures.
- “We really could use greater detail on this from NSW Health,” Martinuik, who is also an honorary senior research fellow with the George Institute for Global Health, says.
- ”Martinuik says the public also needs more detail on why people had not sought a test sooner if they had symptoms while out in the community.
