Ancient technology wins: Not only are quarantine and isolation measures useful, they’re the best tools we have.
Some people don’t seem to realize that the only reason the daily growth of infections is slowing anywhere, is thanks to drastic quarantine measures or changes in human behaviour. We can see this in graphs from Italy, Spain, Norway, South Korea, Switzerland, Germany, and China, but not in Sweden or Brazil where there’s not much quarantine and not much slowing of growth curves either. In all of the former, the big meaningful actions were followed around 12 days later by an obvious slow down.
Willis Eschenbach, for example, wondered If Lockdowns Worked, but counted subdivisions of any quarantine type action as a measure of the severity when it’s more a measure of the wordsmithiness or indecision of leaders.
To see if major action matters, it’s better to look at the dates that borders, schools and shops were closed. The graphs of daily new cases below show that around 12 days later in so many countries, the growth in cases slows too. The delay is due to both the incubation period of Covid-19 and testing. By the time a lockdown is declared (or […]
NEWS: A group say they have developed five antibodies from the old SARS antibody stocks that with tweaking can now bind well to the SARS-2 novel coronavirus.

If they get through all the testing phases and ramp up production, in theory, these could be ready for mass use in September (but everything would need to go right). They could be injected into patients and within 20 minutes these antibodies would bind to the virus and stop it entering cells. The protection might last 8 – 10 weeks before someone would need another dose.
This could be a gamechanger, but beware before anyone gets too excited, this is very early days — “protoplasm” days. There are a lot of steps to rush through.This group have searched and evolved the protein with their supercomputer which has a huge library of antibodies. They claim to be certain it binds to the virus — and to exactly the right part of the virus, but they haven’t actually done that yet — they’ll send the antibody to a military secure lab to do that. Then […]
It’s a big natural experiment
Swedish people are still going to schools, restaurants and gyms. Even the cinemas are running. Apparently Sweden is taking the punt that there are many asymptomatic infections out there, despite having no data, and not doing any structured screening to get some either. They are also betting that immunity to this form of coronavirus will last a lot longer than the coronavirus colds where herd immunity is irrelevant one year later.
All recommendations are made by the Public Health Agency. Apparently they are learning from the 1918 influenza spread, and thus successfully “fighting the last war”. Swedish doctors are reportedly not happy about it. Probably because their idea of being doctors is not where you choose which 60 year old mother lives and which one dies, or where the doctors work round the clock and many of them get sick themselves, and some die. Gruelling is not the word.
Gatherings of 50+ people are banned, and the 70+ age group have been told to avoid social contact.
I predict that as the ICU units overflow, or even before, they will move to serious measures like the rest of the world as the inhumanity of the […]
How big should that gap be?
The WHO recommends “3 feet”, the CDC recommends 6 feet, but new research shows they got the model wrong and we might need to be 30 feet apart. Not to mention that the cloud of aerosols can wander suspended for hours. So we may need to be 30 feet and three hours apart.
No wonder churches and places where people sing are such high risk events, and why an astonishing 12,000 health workers are infected with coronavirus in Spain.
They aren’t sure if their new findings have clinical implications, which says a lot about how much we don’t know. The 27 ft distance applies to sneezes, so if the other party isn’t sneezing you might not have to be so far. Lucky sneezing isn’t that common, though the dry cough is. Personal trainers at 27 feet is going to be tricky.
UPDATE: Some readers ask whether one new study is even worth reporting, accusing me of “scare tactics”. I’ve been reading medical papers now for over 20 years, so forgive me if I found the results here so banal that I didn’t mention that this result is barely new, and very well […]
Right now Australia has one of the lowest death rates from coronavirus in the world. With 4,561 cases but only 19 deaths, the clumsy Case Fatality Rate is only 0.4% — lower even than Germany. While some commentators think that’s a reason to ease up it may be partly due to temporary good geographical luck. Plus winter is coming…
1. Australians with Coronavirus are younger (for the moment).
Most infections in Australia came from overseas travel — something the 20 to 70 year olds do a lot of, but apparently the 80+ age group aren’t flying on 20 hour long haul trips across the Pacific. (Last week the most common source of Australia’s cases was the USA, especially Aspen). This week the main source is Europe, and the nation called “cruise ships”. If and when the virus starts to spread among the older cohorts the death rates will rise. (Unless we figure out that treatment first).

Compare the ages groups of patients in Korea and Italy. Fully 40% of Italian (known) cases are 70+.
