Just a point to note on these: they may not be effective until 2-4 weeks after the symptoms subside. I can’t find the article I read to link to at the moment. Worth checking though.

The self tests are "lateral flow" tests. They're not very sensitive, but cheap. The ELISA tests being rolled out now over here are lab tests. You provide a blood sample and get a result a few days later. For early diagnoses, the PCR tests are still the only option.

Just to be clear, the lateral flow tests are ELISA tests under the hood, they use a visible colour change (or release) and are qualitative tests. The laboratory ELISA tests typically need a spectrophotometer to read and are quantitative tests, that is instead of just saying "yup, saw some antibodies" they will give a quantitative reading in something like units/ml, which also allows a bit of interpretation to be given to the results.

Don't know where the numbers come from, but the amount of tests per million people is interesting. If accurate, Australia should exhibit a similar development of deaths vs. confirmed infected as Germany.

Doubt it. Germany has several times the population, so even if the tests/million is higher, the number of people available to be infected is smaller. Especially if you factor in the much higher population density in Germany. Australia is BIG.

As far as I understand many of those cases occurred in China where people stuffed themselves full of suppressants, appeared to recover and went about their business and crashed again later. This may have triggered the instituted ban on suppressants.

Meanwhile it seems there is a propaganda war going on in Italy between Cuba, China, Russia and the US about who can deliver the most support. :palm:
Ofcourse there is a lot of chest beating going on while in reality France has delivered more face masks to Italy compared to Cuba, China and Russia.
