In contradiction to a tabloid link posted here (and removed) that claimed a "leaked report from the five eyes confirm virus from a lab" a couple of days ago, a more reliable source states the opposite:

"Five Eyes network contradicts theory Covid-19 leaked from lab"

There is no current evidence to suggest that coronavirus leaked from a Chinese research laboratory, intelligence sources have told the Guardian, contradicting recent White House claims that there is growing proof this is how the pandemic began.

The sources also insisted that a “15-page dossier” highlighted by the Australian Daily Telegraph which accused China of a deadly cover up was not culled from intelligence from the Five Eyes network, an alliance between the UK, US, Australia, New Zealand and Canada.

British and other Five Eyes agencies do believe that Beijing has not necessarily been open about how coronavirus initially spread in Wuhan at the turn of the year. But they are nervous about getting involved in an escalating international situation.

that's was similar to one i posted about a possible patient zero, also removed. glad that this has been up for discussion. regardless of it being 'tabloid' news (although i posted links to multiple sources) it still needs to be discussed.

Suppose we need to keep an eye on what is happening in Australia with the bubble joining.

From ABC Yesterday,
Coronavirus cases in Victoria climb by 22, including 19 more cases at meatworks
https://www.abc.net.au/news/2020-05-04/coronavirus-victorian-cases-climb-cedar-meats-abattoir-brooklyn/12209776

Posted today another few cases on ABC.
"
Victoria has recorded 17 new coronavirus cases including another 11 cases linked to a Melbourne meatworks.
More to come
"

There was some more on the cases in a Melbourne school that has a familiar ring to it.

"
A coronavirus-infected teacher who led to the shutdown of a Melbourne school says he was rejected for testing three times.
Keith Campbell believes he had the virus back in March, but attempts to get tested were repeatedly denied because he did not meet the box-ticking criteria.
"

DS248:

Re end of local transmission. This is the HK government CDB take on when it can be concluded that local transmissions have stopped.

https://www.news.gov.hk/eng/2020/05/20200504/20200504_171023_951.html?type=category&name=covid19

Its Communicable Disease Branch Head Dr Chuang Shuk-kwan told a media briefing this afternoon that the virus has an incubation period of up to 14 days and that the centre will consider that local transmissions have stopped after two incubation periods.

She said: "Although we have already observed one incubation period and the situation is getting better now, we cannot conclude that the local transmission chain has been cut.

Thats assuming that all infections are isolating, and have not spread to others, if they have spread to others reset the clock over and over. Thats the problem.

Two 14 day intervals should be adequate time for any latent undetected cases to come to the surface. Even if asymptomatic cases at the start of the period, eventually people they infect (if any - see below) will become symptomatic.

Recent research (links below) investigating the first 100 cases in Taiwan found high transmissibility of COVID-19 before and immediately after symptom onset. No cases of infection occurred more than 5 days after symptom onset. A small number of cases but it does indicate (very?) low infectiousness more than 5 days after symptom onset. Other results & findings of interest:

Median incubation period 4.1 days (95% credible interval [CrI], 0.4-15.8). Other investigations have estimated median incubation period at a bit over 5 days.
Median serial interval 4.1 days (95% CrI, 0.1-27.8)
Close contacts of cases presenting with severe disease were at a higher risk compared with close contacts of cases presenting with mild disease (risk ratio, 3.76 and 3.99 for severe pneumonia and acute respiratory distress syndrome/sepsis, respectively)
None of 9 asymptomatic case patients transmitted a secondary case
But note that 'asymptomatic' is not the same as 'pre-symptomatic'. The latter were infectious.
"Our findings agree with the recommendation from the WHO to use 4 days before symptom onset as the starting date for contact tracing"

The third & fourth points suggest decreasing transmissibility with decreasing severity, which is positive & supports conclusions elsewhere for comparatively low risk from children (symptoms generally mild)

It's good that Trump is very different from Bush in that he'll keep asserting the conspiracy theory without offering any proof while Bush actually pushed really hard for the intelligence agencies to manufacture the evidence he asserted existed. He kept pushing for a casus belli for Iraq until eventually enough flunkies at different agencies, angling for promotions or whatever, scraped together sufficient rumours and half-truths to create the "evidence" that Bush needed. So for once Trump's incompetence/willingness to assert things without proof is a good thing.

No new cases today, minus one case that is not COVID (was being tested).

Well at least some good news: Covid19 may mean the end of battery farming office workers.

@ezbee, you are onto it already, the Australian Broadcasting Corporation (ABC) www.abc.net.au/news is the 'best' source for reasonably unbiased and paywall-free news in Australia.

IMHO, the Murdoch media should be avoided even when free

The Sydney Morning Herald (www.smh.com.au) is pretty good but paywalled, owned by the Nine Network who bought Fairfax including the NZ Stuff group.

IMHO, the Murdoch media should be put up against a wall and shot. Fox News in particular, should be shut down and prosecuted for high treason and crimes against humanity.

Interesting to note that of the 164 currently active cases, 122 are related to the 16 clusters.
