The good news — babies and children appear to be not at risk. The not-so-great news, people over 80 in China have up to a 15% fatality rate (usual caveats, based on unreliable communist statistics and will hopefully be lower for many reasons, see below.) Note that even with the “one child” policy effects in China, that most western nations have a higher proportion of older folk — especially France, Germany and Greece.
The news on “rates of severe cases” is mixed. Singapore, Japan and HK are looking at 15% early rates. But many other nations are looking at 0%. Hmm?
A/ Fatality rate per age group. b/ Demographic age groups in different nations. C/ Relative mortality compared to China (apparently due only to the age demographic). | Click to enlarge. Age and Sex of COVID-19 Deaths REF China CCDC
*Fatality rates calculated by the China CCDC won’t include many unrecorded asymptomatic infections, nor the deaths outside hospitals and don’t appear to include the lag either. But they show which groups are at most risk.
Worldometer now gives us rates according to sex and preexisting conditions. (Reproduced below). Basically there are 30% higher death rates in men, […]
In short:
Outside China, 2% of cases have progressed to “severe”. But if the lag is eight days then progression to severe is more like 5%. In China about 1/5th of severe cases are “Critical” If that rate occurs in the West, hospitals will be overwhelmed if just 1% of the population gets infected. In Singapore, the doubling period for confirmed cases is about nine days. Currently the spread is not exponential outside China (most days)
News today: First victim in Europe — an 80 year old Chinese tourist.
Stats: Total cases outside China: 787 Deaths: 4 Severe cases: 18 (2%)
Early days of “outside China” data
The 2% rate of severe cases is an underestimate above. There is an eight day lag from diagnosis to “severe,” and then a longer lag to death. Total cases outside China on Feb 8th was 354. So a more realistic estimate is that about 5% of confirmed cases outside China have now progressed to “severe” (i.e. 18/354).
What does severe mean? It appears “severe” means hospitalized but not necessarily in ICU. In China, the rates issued in a Feb 7 press release were 82% mild, 15% severe, and 3% critical. From […]
Partial post hoc reactive quarantine holds seven planes at London airport– seriously?
Madness. Eight planes have been held up for hours in London airports as they land with people with coughs and colds and try to check suspected cases. By the time people are symptomatic, its too late. Temperature checks may catch the most contagious people but now one person with a unrelated common cold can also cause a major and unnecessary disruption while other infective people can freely fly in and walk straight through.
Asymptomatic people can potentially infect 2 to 3 random people (or 10) who may then also infect 2 – 3 random people each before the Epidemiology SWAT Team realizes and starts testing and tracking. We play an impossible game of catch up in a race to isolate all possible contacts.
HOURS of misery in coronavirus lockdown at Heathrow:

Passengers endured hours of misery at Heathrow Airport this morning when up to eight planes were put on lockdown over coronavirus fears after passengers on board complained of symptoms of the deadly virus.

Global Markets were shaken by the sudden rise in numbers out of China yesterday. But the increase was not a surprise for anyone who has been watching social media and the measures being taken in China. That China is now allowing the WHO in may be an admission that they really do need help. The explanation for the jump is that China changed the definitions. They are also admitting that there may be many cases of people with low grade infections, but also unattributed deaths as well. For days the ratio of cases to deaths was suspiciously 2.1%, 2.1%, 2.1% … Now perhaps it’s a tiny bit closer to the truth.
The tally outside China continues to rise: there now 587 cases, with 3 deaths (1 new one in Japan) and 24 people classified as “serious critical”. These are the key figures to watch. We expected the number of cases that were severe to rise as the five to eight day lag unfolds from the first symptoms to the onset of breathing trouble. So at the moment 4% of cases outside China are headed for hospital intervention, perhaps ICU (does anyone know the definition of “Serious Critical”?). That will keep […]
So Coronavirus is now CoVID-19.
We’ve been walking the cusp of containable versus pandemic for two weeks but the growth of infections outside China is just a bit too fast, a bit too random and the news suggests its easier to spread. At least the number of severe cases outside China is still only 2% of the total. But there’s a lag of a week or two, so that’s likely to rise. If it is even possible to stop, I suspect only the mass closure of borders will do.

While Australia and the US and even India have the illusion of stability, the rise in Singapore, and on that ship is hard to ignore. Singapore is doing advanced tracking, yet still it spreads (see the chart, right). The difference between Singapore and Australia may be part luck — one superspreader versus one man who didn’t infect anyone on a whole plane.What matters then, is just how many people are superspreaders? The one ray from Singapore is that 15 people on that list are already listed as recovered. When I say we hope it’s […]
One day ago, the statistics were looking good but there have been a few ominous shifts. Another 26 infections have been recorded, some in a French ski chalet, some in Singapore —at least three of which are hard to explain. These appear to be transmissions outside China, which is what we are hoping to avoid. It’s bad, but could have been a lot worse. Fortunately the Diamond Princess tally hasn’t risen much — standing at 64. Another plus — it’s almost two weeks since one passenger on a Tiger Air flight in Australia flew as he was coming down with symptoms yet the other 157 passengers appear to be OK. Promising.
…
Just 2% of cases so far are severe outside China (but that may grow)
The all important statistics outside of China are starting to accrue — So far there are 355 infections. Of those, 35 have recovered and only eight are marked as severe (see the table below). It’s good news that only 2% are severe, however it’s too soon to know — 90% are still unwell.
The illness appears to be less severe outside China, but a new study reports that this virus often looks benign […]

Assuming that these official statistics from China bear a faint connection to reality (in trend, if not number) this may be a sign that the draconian quarantine is starting to work. If real, it is only a slight slowing in the rate of growth, but it’s a good sign — one I have been looking for. It is a barely visible slowing of the rate of change in the cumulative tally of victims. The exponential curve is slowing. Of course, if this takes off in Africa this would be but a pause…

The virus which had been growing at 50% a day two weeks ago, slowed to 20% last week, and 11% today. One week was such a long time ago in exponential land. Last Friday night the tally was 9,700 infected, and 213 deaths. At that point, no nation had cut off flights or refused visas. UPDATED: Saturday.

Sadly the brave doctor who tried to warn the world has been taken by the virus. Ominously he was only 34 — presumably with no “underlying disease”. Instead of listening to him, the Communist […]
A fateful decision that led to many deaths
The Samoan Islands, 1896 | Wikimedia
Western Samoa and American Samoa are side by side islands in the Pacific. When the Spanish Flu arrived in 1918, one would instigate a quarantine while the other had a trading community that did not want to stop trade. American Samoa survived the Spanish Flu without a death. Western Samoa kept trading and lost a quarter of the population.
Influenza 1918: the Samoan experience
John Ryan McLane
In 1918 the Samoan archipelago was split between American Samoa (a United States territory) and Western Samoa (previously a German colony but under New Zealand governance from 1914). The 1918 influenza pandemic killed a quarter of Western Samoans, while leaving American Samoa unscathed.
The dangers of ship-borne disease were well known, and exclusion of many diseases, especially plague, had been implemented since the imposition of colonial governance nineteen years before.
On 30 October 1918 the Union Steamship Company’s Talune left Auckland for its run through Polynesia… The new, more lethal influenza variant had arrived in Auckland with the spring, and several crew members were ill.
Western Samoa was a German colony that […]
Ooh. Are these the real figures? Is someone on the inside trying to leak out the truth?
There are claims tonight that a flickering set of figures have appeared that are much higher than the official tolls. These ghostly statistics have appeared three times then switched to the much lower official tally. But each time they grow — almost as if there are two sets of data, one for officials, and one for the public.
Ominously, the flickering death tally was 80 times higher than the official one. The infections were ten times higher. If it’s true the death rate may be far worse than the 2% bandied about.
If they are real, this changes everything. If they are fake, who or what would benefit? A glitch?

Tencent may have accidentally leaked real data on Wuhan virus deaths
Tencent briefly lists 154,023 infections and 24,589 deaths from Wuhan coronavirus

TAIPEI (Taiwan News) — As many experts question the veracity of China’s statistics for the Wuhan coronavirus outbreak, Tencent over the weekend seems to have inadvertently released what is potentially the […]
The latest news coming out is mixed. The live map and latest count of 2019-nCoV shows 20,000 confirmed infections, 426 deaths, and most importantly, a spread to 28 countries. It’s slightly encouraging that there are no extra cases in Australia and good to hear 3 of the 12 have been sent home, declared “recovered”. However the incubation period since flights were closed is still only halfway to the average (of 5 – 6 days) so it’s too early to tell.
A South Korean has tested positive after visiting Thailand (not a good sign, but the statement didn’t “rule out China”). Japan has quarantined a whole cruise ship (like Italy did). One passenger came down with the virus in Hong Kong. The whole ship of 3700 is confined to rooms, awaiting test results. It’s reassuring that so many tests can be done. (Yay, Japan). Meanwhile door handles can carry the virus. Soap and hand sanitizer could help a lot.
On the plus side, one team in Thailand say they have treated one patient successfully with anti-virals. It’s only one case, but a nice thought. How big are those stockpiles? The other plus, is that summer may slow it down. Best case […]
The WHO could have declared a state of emergency earlier. Instead it delayed the announcement, praised China’s transparency, and recommended countries allow planes potentially carrying a deadly virus continue to fly freely. The WHO waited until the 2019-nCoV virus had spread to 18 nations before declaring an emergency. Wasn’t it an emergency with the first foreign case or the first case of symptomless transmission?
Follow the chain, or rather the Belt and Road
The WHO Director General is Tedros Adhanom of Ethiopia. From 2012 – 2016 he served as Minister of Foreign Affairs in the one party government that rules Ethiopia. This is the same party that borrowed billions from China to build a railway line, then struggles to pay it back. In Africa, Ethiopia is the second largest debtor nation to China — owing $13 billion. As Foreign Minister Adhanom praised China for African loans, looks like he was the man to line them up. We also note that the one-party ruling party of Ethiopia is called the Tigrayan People’s Liberation Front which was once a Marxist Lenninist far left group — labels it dropped after the Soviet Union collapsed. (Thanks Maurice for these tips).
Suddenly there might be […]
US and Australia close borders and everyone outside China starts tracking contacts…
The official deaths tally has risen to 259, but for the first time the “total recovered” at 287 now exceeds the total deaths. Evidently it’s quicker to die than to recover.
Australia remains the “leader” of the Western nations with 12 confirmed cases. Thankfully, it and the US have finally got serious and both announced today that they would stop people from China from flying straight in. Citizens can return with a two week isolation or quarantine period, but foreigners cannot. This is very good news (as far as virus control goes). Now all the same nations will be furiously, laboriously tracking and tracing the hundreds of potential contacts. In a few weeks we’ll know how contagious it is, and how deadly. And maybe, with much money and dedication we’ll even stop it.
Though in a few weeks a host of secondary countries may develop their own epidemics and virus-free countries will need to block them too.
What’s really remarkable here is how useless, to the point of negligence, the World Health Organisation is.
US and Australia close borders to Chinese arrivals
BBC News: The […]
Been trying to do a Corona thread for three days, but every time it was half finished everything changed.
The WHO have finally declared a state of emergency, something that seemed inevitable as soon as we knew the virus could be transmitted by people without symptoms. Russia, Mongolia, and North Korea closed their borders Thursday. Hong Kong announced a temporary closure. Singapore has now closed its borders too. Mark Steyn meanwhile, marvels that healthy US citizens are being advised not to go to China, but it’s apparently fine for sick people to travel the other way. Extraordinarily a cruise ship with 6,000 passengers was “stuck” off Italy, waiting for clearance for two Chinese people who had symptoms like a flu. Fortunately they must have just had the flu. The ship was cleared. And so it is around the world with a mosaic pattern of super actions, versus business as usual.
British Airways has suspended all flights to and from China, as have many other airlines, but in a city by city way. The virus is now present in every region of China. It’s not clear why all flights to and from China have not been stopped. On ABC news Australia’s […]
Fifteen years of missing data tells us everything we need to know
Peter Ridd and Jennifer Marohasy are continuing to follow up on the death of the Great Barrier Reef. Strangely, while everyone professes to care, and cry, and Malcolm Turnbull casually tossed half a billion at it, we see the extremely radioactive oddity that no one is worried enough to bother measuring the actual supposed decline of the seventh wonder of the modern world. Fifteen years is a long time to overlook that. Many panicked press releases have gone under the bridge yet apparently AIMS (and all the others) just want to keep quoting the shrinking growth rates, but not keep track of them.
On top of that, Peter Ridd and Jennifer Marohasy have spotted a pretty major flaw in the methodology for that much quoted study that claims growth on the reef has slowed by 15% from 1990 to 2005. If that number is right, the reef will have ground down to a 30% decline by now [in growth rate]. Disaster, disaster. Worthy of a hundred press releases and a thousand grants. So either it just hasn’t occurred to AIMS et al to keep studying the reef they […]
Attenborough turned a natural phenomenon into an advert for the Climate-scare industry. As Benny Pieser at GWPF points out Falling Walruses were turned into the new posterboy of climate change, “It would be a sad legacy if he did not set the record straight.””
Here’s the brief synopsis in case you don’t feel like watching walrus horror flicks.
Though this old video that Polar Bear Expert Susan Crockford found is kinda novel — you can see scientists test theories and then throw them out.
Biologists in 1994 noticed walruses falling down a steep incline. They tried to figure it out. They scratch their heads. Admit they don’t know. They saw it happen three years in a row, and as many as 120 walruses met a flattening end.
The first theory was the animals were trying to escape severe storms, but the next year the weather was perfect. Walruses rolled and crashed again. So did that theory.
The second theory, was that perhaps the sights and sounds of humans were putting them out… but no — discussions with locals suggested not.
The third theory was that they were suicidal. But Dr Seagers, quaintly, doesn’t think we should put human thoughts […]
The IPA team interview Peter Ridd. He explains that what’s happening on the Great Barrier Reef with coral bleaching is a normal cycle. He tells his story of being censured at James Cook university, but admits the state of free speech at universities in Australia is non-existent — even after his win. They discuss how we might reform science with audits (universities are almost a lost cause). We’ll probably never know how many scientists think similar thoughts to Peter Ridd. We know that they’ll need a $250,000 legal fund if they say so.
UPDATE: Importantly — Ridd says that the admin are still utterly convinced they are right. They have no remorse, no recognition of why they were wrong. Does this mean admin staff now decide what science is, not Profs? Apparently so. They hold the purse strings, not the Profs. Power follows the money. Indeed, JCU has no commitment to free speech; they’ve now removed the clause that ensured Ridd won. In their minds, their mistake was not in being draconian, but being careless with legal clauses. The Deep State tightens its stranglehold on science.
Peter Ridd: Of all the ecosystems in the world, the reef is one that’s […]
Squid, “surprise” are going to do well with climate change. (If only it was going to happen).
In the new post-CO2 world, corn and soy may become weeds, but squid may take over the oceans:
Squid will survive and may even flourish under even the worst-case ocean acidification scenarios, according to a new study published this week.
Dr Blake Spady, from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University (JCU), led the study. He said squid live on the edge of their environmental oxygen limitations due to their energy-taxing swimming technique. They were expected to fare badly with more carbon dioxide (CO2) in the water, which makes it more acidic.
No academic could have guessed that squid would have evolved ways to control their own blood pH:
“Their blood is highly sensitive to changes in acidity, so we expected that future ocean acidification would negatively affect their aerobic performance,” said Dr Spady.
Atmospheric CO2 concentrations have increased from 280 parts per million (ppm) before the industrial revolution to more than 400 ppm today. Scientists project atmospheric CO2 — and by extension CO2 in […]
Just another way cheaper electricity saves lives.

It turns out hotter rooms have higher indoor pollution. Levels of formaldehyde are lower in the morning and rise with the temperature. Air conditioning in hot summers, keeps the temperature down and will reduce the amount of formaldehyde and other pollutants from out-gassing from furniture and gypsum walls. Obviously those who can’t afford to run the air conditioner and who live in warmer rooms in summer will be exposed to more pollution.
Though the worst situation was in 1970s homes with radiant heaters installed on gypsum sheets. In that case, people who can’t afford to heat may avoid some fumes.
Opening windows will clear out the indoor pollution, but houses are increasingly being designed to stop draughts to be more energy efficient.
The message: get rich or open windows when it’s nice outside, move those bar heaters off the walls, and buy peace lilies, bamboo palms, and dracaenas.

Mysterious CO2 activity in New Zealand shows Phytoplankton at work
Tom Quirk both finds a mystery and solves it.
Emiliania huxleyi coccolithophore | Alison Taylor.
Carbon dioxide is a “well mixed gas” yet CO2 levels over New Zealand start rising there each year in March — a whole month before we see it CO2 start to rise over Tasmania. Air over Cape Grim in Tasmania will be blown by the prevailing wind over to New Zealand about five days later. So these two stations should be showing similar numbers throughout the year. Instead some process in NZ is pushing up CO2 early. Levels also peak earlier in New Zealand, and by September, in early spring, some process around NZ is pulling the CO2 out of the sky. Both NZ and Tasmania share large forested areas, so that wouldn’t explain the difference.
Quirk wondered if it had something do with phytoplankton, so he searched for satellite data that measures chlorophyll in the ocean and shows, voila, that there is major activity right around the Baring Head station at the same time as CO2 levels are falling. Indeed, the station is smack in the middle of a mass phytoplankton bloom.
He […]
Two different models predict two totally different futures. On the left, catastrophic extinction. On the right, happy bats. Click to enlarge
Yesterday a UN supercommittee of 145 scientists from 50 countries declared that one million species are set for extinction. The same day, ten other scientists published a paper pointing out that most modelers forget to allow for genetic variation and thus overestimate the extinction rate. (It’s like they’re modelling the World of Clones – take one small study, pretend they’re all the same — extrapolate globally.) Have a look at the big difference in model outcomes in figure 1 (right).
As I keep saying, 500 million years of brutal climate change means almost every species carries around an industrial tool-kit of handy genetic tricks. Matz et al estimated corals already have the genes to survived another 250 years of projected IPCC catastrophe (in the unlikely event that it happens). Liew et al showed corals even have epigenetic tricks as well as genetics ones. Another group showed when corals are heated something like 74 different genes are activated — often genes that we don’t even know what they’re there for.
