BA.2 is not Omicron. And what are BA.4 and BA.5?

BA.2 is very different to BA.1 and BA.3. Why is it called Omicron? Because it came from South Africa around the same time. I thought the whole purpose of using Greek letters was so we could not tell where the variant came from. Delta always reminds me of the Ganges delta plains and hence of…

South Korea to relax all mandates except for masks.

Cherry blossoms in a Seoul park this week. South Korea will consider ending its outdoor mask mandate this month, but an indoor mandate will stay in place, the prime minister said.Credit…Ahn Young-Joon/Associated Press

The subvariants of Omicron have exploded. Australia is getting buried in new subvariants from within and from the outside. Welcome to the “New World Disorder”.

Last I looked (a couple of day ago) we had 54 subvariants of Omicron listed by GISAID. BA.1 was the one that swept the world first. BA.2 looked more ominous as its spike protein was quite different to BA.1 and BA.3, and it subvariants are the ones I have been most concerned about. Look at…

How many people actually have covid? x20?

I assumed that with vaccines masking/reducing/preventing symptomatic illness that there would be at least as many as counted cases who are asymptomatic and not counted. This article about the covid19 outbreak in Shanghai blew my socks off. “Shanghai on Tuesday reported 22,348 new asymptomatic coronavirus cases and 994 symptomatic cases for 11 April, the local…

Was Denmark too hasty to declare that the coronavirus was just a flu and life was now normal again?

When Denmark’s Case Fatality Rate (CFR) dropped to 0.04% (7-day-runng average) in January 2022, the government of Denmark declared the pandemic was over. With a CFR so low, noting that the CFR for influenza is about 0.1 to 0.15%, that made reasonable sense. In early February most restrictions were subsequently lifted. It was said that…

Australia has BA.2.3. Looks ominous.

Omicron subvarinat B.A.2.3 is growing in Australia. It looks ominous as the Philippines Hong Kong and South Korea recently had high CFRs and BA.2.3. CFR=Case Fatality Rate = Death Rate

Deltacron has landed in Australia

The dreaded recombinant variant #deltacron which I warned has not disappeared has now arrived in Australia. It has the spike like Omicron but the other parts are like the Delta variant. If it is 10 times worse as Omicron, which delta was, then the death rate could be hundreds a day, even close to 1000…

How many people around you are carrying covid19 right now in WA?

There will always be a large virus pool from which new variants will form, so even if people develop immunity to one variant they will not be immune to new variants. This virus can become weaker one year but more deadly the year after.

Rapid Antigen Tests are Useless

I was trying to make sense of this paper I reference below. My conclusion was that the RAT is 37% more accurate on average compared to a random 50/50 result for Omicron. That does not sound too great to me. A big drop from the delta variant. Why are we even using this crap? The…

What is Omicron XE? Should we worry?

From what I know Omicron XE is some hybrid on BA.1 and BA.2 subvariants of omicron. The Omicron variants are the most infectious variants so far but their case fatality rates seem to be quite low 0.1 to 0.3%. There is still some uncertainly with BA.2. It may be more virulent. I have been unable…
