The NT is one of three jurisdictions that haven’t confirmed any new coronavirus infections in weeks.

June 02, 2020 17:34:08
The Top End has marked ___ since its last new COVID-19 infection.
This is the second-longest period any jurisdiction has passed without confirming a new case since the disease was first detected in Australia.
The current record is held by NSW, which tallied 35 days between the announcement of the state’s first three cases, on January 25, and its fourth and fifth cases, on March 1.
The data for each state and territory is among the charts below, which provide a guide to how Australia is faring in the fight against the spread of the coronavirus pandemic.
The latest update was at ___
Skip to a section:
To date, Australia has recorded ___ confirmed casesof COVID-19, including __ deaths.
(Tap/hover on any chart for more information.)
These figures are from a national dataset of every confirmed case since January 25, when the country’s first four cases were reported.
Compiled by ABC News, the dataset tracks cases as they are confirmed by state and federal health authorities. It is supplemented with additional reporting by ABC News and updated daily.
Roughly ___ , or ___new cases, were reported in the past 48 hours.
(Note that national daily and cumulative counts are likely to be lower earlier in the day, as some states/territories will not have reported their figures yet.)
___ has gone the longest without any new confirmed cases, tallying ___ since its last new diagnosis. It is followed by ___ and ____.
For all three jurisdictions, this is the longest each has passed without recording any new cases.
NSW holds the current national record. It counted 35 days between January 25, when health authorities reported the state’s first three cases, and March 1, when the state confirmed its fourth and fifth cases.
In each jurisdiction, the longest period without any new confirmed cases is 27 days in Victoria, 19 days in SA, 15 days in Queensland and 12 days in WA.
Most people diagnosed with COVID-19 in Australia have now recovered, leaving ___ confirmed cases still current or “active”.
Nearly three-quarters of current cases are in NSW.
The ACT and the NT have no known current cases of COVID-19, while SA has one active case.
Across the country, __ people or __ have recovered from the disease.
Figures show that the vast majority of people diagnosed with COVID-19 do not need to be hospitalised.
The chart below shows the number of people in hospital, including in ICU and ventilated, in each state and territory.
Of ___ current or “active” cases, only __ (or __) are receiving hospital care.
This includes __ patients in ICU (__ of current cases), __ of whom are ventilated (__ of current cases).
These hospitalisation figures are based on a snapshot of a point in time, rather than a cumulative count of patients hospitalised since the virus was first detected in Australia.
Case numbers and diagnosis rates are heavily influenced by the rate of testing.
On May 11, the number of samples tested nationally surged to a record high of 33,300 tests per day, based on the five-day moving average. This followed the decision in late April to broaden Australia’s coronavirus testing regime to include anyone with flu-like symptoms.
The surge was largely driven by increased testing in Victoria, where the number of tests per day leapt more than five-fold in the first 10 days of May, and NSW, where tests per day doubled.
The hope is that the number of new diagnoses will continue to fall despite broadening the testing criteria.
A daily comparison of tests and new confirmed cases (using 5-day moving averages for both) suggests that, so far, increased testing has not been matched by a rise in new cases.
Nationally, ___ people have died __.
The highest number of deaths was recorded on April 7. April 16 was the first day in almost three weeks with no deaths reported in Australia.
Most deaths have been of people aged 70 or older. (Tap/hover on a square below for more details.)
At least __ cruise ship passengers and crew, and __ nursing home residents are among the dead.
Together, these two groups account for more than half of coronavirus deaths in Australia.
Nearly all the nursing home deaths were in Sydney. They include deaths at Anglicare’s Newmarch House near Penrith, six at Dorothy Henderson Lodge at Macquarie Park, and two at Opal Care Bankstown in Liverpool.
The Newmarch House figure excludes two residents who had reportedly recovered from coronavirus before they died, so are not counted in the NSW Health death toll.
In Tasmania, 12 of the state’s 13 deaths are linked to an outbreak in the state’s north-west, which forced the closure of two hospitals before Easter.
An investigation found the cluster of more than 120 infections most likely began when two Ruby Princess passengers were admitted to the state’s North West Regional Hospital in late March.
In Victoria, three deaths were linked to a cluster of cases in the oncology ward at Melbourne’s Alfred Hospital.
Across Australia, ___of all confirmed cases were acquired overseas.
However, this figure varies substantially between states and territories. In Tasmania, for example, more than 60 per cent of confirmed cases were spread locally, compared to ___Australia-wide.
Nationally, the source of infection remains unknown in ___ of confirmed cases, up from 5 per cent in late March. This is what authorities refer to as “community transmission” (although sometimes the term is used to describe all cases acquired locally).
Infections from unidentified sources now number __ nationally and account for ___ of all locally-acquired cases.
NSW has the highest rate of community transmission, with authorities unable to identify the source of infection in one-third of locally-acquired cases.

Overseas-acquired infections have plummeted since Australia shut its borders and banned travel abroad.
This is clearly seen in the chart below, which tracks the number of cases added or subtracted daily to each source of infection category, as well as the number of cases still under investigation.
It includes new cases and cases shifted between categories because contact tracing uncovered new information.
Locally-acquired infections (the green and blue lines) started to outnumber overseas-acquired infections around April 4.
But this is mostly because overseas-acquired infections have fallen so sharply. In fact, both overseas-acquired and locally-acquired infectionsare in decline.

Key measures of the spread of infectious disease show that, so far, Australia has been largely successful in “flattening the curve”, although experts warn the situation could change quickly.
One way of tracking a disease’s growth rate is the daily percentage change in total confirmed cases.
This shows Australia’s growth rate has fallen from a peak of nearly 25 per cent in mid-March to less than 1 per cent since April 15, based on the five-day moving average. The aim is to reach zero and stay there.
Another way of measuring the spread of disease is by how long it takes the number of confirmed cases to double also known as the “doubling time”.
This is easier to see when the number of confirmed cases is plotted on a log scale.
On the chart above, each tick on the vertical axis is 10 times the value of the previous tick.
The key element is the slope of the line. The steeper the line, the faster the growth rate. A horizontal or flat line means cases are no longer growing exponentially.
For most of March, Australia’s count of confirmed cases doubled every 3-4 days. However, it took a turn, slowing so much that by early April, it was taking a month or more for cases to double.
Australia’s trajectory is now flat, which means cases are no longer growing exponentially.
A similar kind of chart can be used to compare Australia’s growth rate to other countries.
This one uses the same log scale but rather than exact dates, it tracks each country’s cumulative case count from the day that country reached 100 cases. This brings each country onto the same timeline.
It shows that in many nations, including Australia, the number of confirmed infections grew rapidly early in the outbreak, doubling every 3 days or less.
However several countries, such as Australia, New Zealand, China and South Korea, have since managed to slow their growth rates and now have much flatter lines.
Here is the same type of chart but this time, tracking each of the states and territories from the day it reached 10 cases.
It shows most jurisdictions are on roughly the same trajectory.
___ has the most confirmed cases, making up ___ of the total number of infections, followed by ___and___.
However, the picture shifts when population size is taken into account.
This chart shows the total number of confirmed cases adjusted for population size. (It does not use a log scale.)
It reveals that ___ has the most confirmed cases per capita, having surpassed NSW on April 20. Prior to that, NSW held the grim title for more than six weeks.
More than half of Tasmania’s cases are associated with the north-west outbreak.
___ has the lowest infections per 100,000, followed by ___.
Data on the percentage of tests that come back positive for COVID-19 show __, then __ and ___, have the highest positive test rates.
___ and ___ have the lowest.
Again, this is influenced by testing rates, since the broader the testing regime, the lower the odds of finding positive cases.
Adjusting testing figures for population shows ___ now has the highest rate of testing, taking the top spot from SA in mid-May.
It is the first time since the start of the coronavirus pandemic that SA has not held the top rank for the nations highest number of tests per capita.
However, Victoria’s testing numbers which had consistently lagged other states and territories surged following a weeks-long push that began in late April.
It is now roughly ___ the rate in ___, which has the nation’s lowest rate of testing.
___ and ___ have the second- and third-highest rates of testing, respectively.
Another way of looking at rates of testing is to compare the number of residents to the number of tests, both as a share of the national total.
___ accounts for ___ of Australias population but___of samples tested in Australia, while __ accounts for ___ of the population but ___of tests.
By contrast, ___ makes up ___ of the population but only ___of tests.
Similarly, ___ accounts for just over ___ of Australia’s population, but only ___of tests.
People ___ have the most confirmed cases of any age group.
However, adjusting these numbers for the size of each age group (below) shows people __ have the highest rate of confirmed cases.
They are followed by people __ and people __, and then those ___.
Notes about this story

  • Data used in this story is provided by federal and state/territory governments, either from press conferences, official websites and reports, or press releases.
  • From March 30, some states and territories began adjusting their case numbers as a result of false positive tests or double counting. Often they do not advise when the errors occurred, so in most instances we revise the previous day’s new case count accordingly. For this reason, in some jurisdictions, new case counts may not match figures announced at the time and cumulative counts may not equal the sum of new cases.
  • Federal and state/territory health authorities update their figures at different times of the day, so the numbers shown do not necessarily reflect the same point in time in each jurisdiction.
  • From March 27, federal government data comes from a daily PDF emailed by the Department of the Prime Minister and Cabinet, titled “COVID-19 Update”.
  • Prior to March 27, federal government data came from daily updates to the Department of Health website and a PDF “dashboard” also published by the Department of Health.
  • As of May 5, data on coronavirus-related deaths also relies on figured provided by Anglicare, the operators of the Newmarch House aged care facility in Sydney.
  • Between April 10 and 14, NSW moved a large number of cases between Source of infection categories, effectively reallocating 11 cases from Local – Unknown to Overseas. ABC News has adjusted the daily figures to reflect this.
  • Recovery data for NSW prior to April 21 was estimated by federal health authorities.
  • Data on confirmed cases by age and sex are from the National Notifiable Diseases Surveillance System. It lags both federal and state/territory figures but is the most up-to-date source of age data at the national level. It is updated daily.
  • Population figures sourced from ABS Australian Demographic Statistics, Sept 2019
  • Dates refer to the date the case was reported by authorities, except in these instances:
    – The 5th, 6th and 7th confirmed cases in Victoria have been assigned to the date they were first cited in official press releases. These cases were first announced on March 1, as having recovered from the virus.
    – Dates for the 7th and 8th confirmed cases in Queensland (Diamond Princess cruise ship evacuees) are based on ABC News reports. The 9th confirmed Queensland case, another Diamond Princess evacuee, was first announced in a press release on March 3.
