#Contact_tracing can be a practical and effective way of containing disease spread. But did you know it's even more effective when social groups are involved?

Contact tracing not only cuts direct infection paths but can also prevent indirect spreading routes in groups. We illustrate how it can be more efficient than what would be predicted by models that assume a fully mixed population or a locally tree-like network structure.

Our results show that the outbreak size shrinks as clique size, c, grows, and this is amplified by higher contact tracing success probability α, despite fixed transmission probability p.

🧵 "#Criticality: A Balance Between #Robustness and #Adaptability"

Regarding systems at the #EdgeOfChaos
Identifying #PhaseTransition dynamics
Citing @WagnerEvolution on #Robustness
Contrasting it with #Chaos (fragile, hard to predict, etc.)
And then #Criticality, somewhere in the middle... ImageImageImageImage
With #criticality, due to #PowerLaw(-like) distributions:

"Most of the changes will be small, but for some, you can have large changes."

Someone recently asked me why I, conducting a project on #epidemics, write a paper on #mantras in #Ayurveda. Here is the reason: Early South Asian medical compilations discuss epidemics and how to treat them. They suggest various countermeasures …
Besides more "medical" remedies they suggest also truthfulness, compassion, #mantras, offerings, fasting, atonement, veneration of gods, certain rituals etc. – measures belonging to the class of remedies "depending on the supernatural" (daivavyapāśraya).
In Ayurveda, remedies are usually differentiated into those "depending on logical principles" (yuktivyapāśraya) and those "depending on the supernatural". The former help to balance the bodily humors, the latter shall primarily check all kinds of exogenous harm. Image

This is a big deal. #China watchers, investors & policy/decision makers, pay attention: #CCP has stopped issuing ordinary #passports & other entry & exit documents if u don't have "essential or emergent reasons". This means the #CCP is closing its doors again.
The reason cited in this report is to "protect people's health, life safety, and effectively prevent the importation of foreign #epidemics ( #CCP Virus, #COVID19 "

1/ I read multiple books at a time, and let me tell you, some stark differences between @StatutoryVapeBk & @BarryMeier "Pain Killer: An Empire of Deceit and the Origin of America's Opioid Epidemic"
2/ For example, "On an average day in 2016, 175 people died from an overdose, a rate of seven fatalities pan hour."
Verus:
3/ "At the time this book was published, the CDC reported that there were 64 deaths confirmed in 27 states and the District of Columbia due to vaping-related illnesses."

On Mar 24, we had ~800 #COVID deaths in the US. On Apr 4, when the count was at ~8,000, I predicted ~20,000 deaths by Easter Sunday, Apr 12.

My prediction was spot on. Current tally is 20,600.


1/
In this PEDAGOGICAL thread, I will explain how I came up with this number. This thread is not meant for systems experts.

I became interested in, and very concerned about, the spread of #coronavirus since January 2020, when I saw the initial datasets from #Wuhan.

2/
I am an applied mathematician, and I specialize in modeling dynamic systems, besides other things. I am not an epidemiologist, but the spread of infectious diseases are governed by the same mathematical rules that govern dynamical systems in general.

We need some #GoodNews. Yes, this is a study in mice but this is so far the first peer-reviewed #coronavirus #vaccine study with promising results in @EBioMedicine published by @TheLancet from @PittTweet @UPMCnews @PittHealthSci vaccinologists
When tested in mice, the #vaccine, delivered through a fingertip-sized patch, produces #antibodies specific to #SARSCoV2 #virus. Researchers were able to act quickly because they already laid the groundwork during earlier #coronavirus #epidemics.
Compared to the experimental #mRNA #vaccine that entered clinical trials, this one - called #PittCoVacc, short for #Pittsburgh #Coronavirus Vaccine - follows a more established approach, using lab-made pieces of viral protein to build immunity (same way current #flu shots work)

"The Lancet‘s fraudulent concealment of genetics, and its own conflicting interests, while condemning #coronavirus conspiracy theorists, gives the appearance of “crisis capitalism,” and complicity in the COVID-19-SARS/HIV-1 #Wuhan ‘Event 201‘ biocrime." Image
The 'Scientific' arguments going on behind the scenes on #Covid_19 should be a wake-up call to the 'TRUE' dangers the world is being exposed to! 'BOTH' sides of the argument are labelling the other 'Conspiracy Theorists'. Only one of them can be! Image
The Lancet writes that "Conspiracy theories do nothing but create fear, rumours, and prejudice...." #Covid_19 Image

Lessons from past #coronavirus & #influenza #epidemics suggest that #viral #infections can trigger acute coronary syndromes, arrhythmias, exacerbation of heart failure owing to a combination of a significant systemic inflammatory response plus localized vascular inflammation.
#COVID19 may either induce new cardiac pathologies &/or exacerbate underlying cardiovascular diseases. A large proportion of patients have underlying cardiovascular disease &/or cardiac risk factors. Factors associated with mortality include male sex, advanced age, comorbidities.
Acute cardiac injury determined by elevated high-sensitivity #troponin levels is commonly observed in severe #COVID19 cases & strongly associated with mortality. Acute respiratory distress syndrome is also strongly associated with mortality in patients with #SARSCoV2 infection

I am pretty sure most of my followers don’t buy into the conspiracy theory that #COVID-19 is a #bioweapon created by the United States (or anyone else), but for anyone who does, here’s a quick history lesson. (1/7)
The US eliminated its offensive #biowarfare program in 1969. President Nixon said at the time, “Biological weapons have massive, unpredictable, and potentially uncontrollable consequences. They may produce global #epidemics and impair the health of future generations.” (2/7)
America’s renunciation of its BW program was the first time that a major power unilaterally abandoned an entire category of WMD. For more on Nixon’s decision, @WMDCenter has a great case study by the late Jonathan Tucker, available online: wmdcenter.ndu.edu/Portals/97/Doc…. (3/7)

Something a lot of people may not know about me is I am really, really into genealogy. So, last week I was tracing one branch of the family and I noticed something that seemed odd. 1/15 #cdnhealth #epidemics #medicine #History
Adult siblings and cousins were losing family members over a certain time period. One fellow lost his wife and their three children over the winter of 1848/49. Then another in this family lost two children, same time frame. 2/15
Now, when you see the deaths of a mother and infant, you are liable to assume it was complications of childbirth. Infant and maternal mortality rates were much higher back then. But then you see the 3 y/o, 5 y/o, and 7 y/o also died.... It had to be something else. 3/15

1. Just wanted to mention something about the coronavirus #COVID19 situation, for anyone unfamiliar with how federal/state governments, hospitals, first responders, school systems, etc. prepare for specific types of emergencies.

You may already know this, but just in case...
2. In a situation like this, it's good advice to say "don't freak out". That's not to say people shouldn't worry about #COVID19 at all. The whole point of emergency preparedness is to "prepare". Regardless of what 45* says, remember that fed & state governments ARE preparing.
3. Federal, state, and local governments, as well as hospitals and first responders, ALREADY have "standard operating procedures" in the event of specific types of emergency scenarios. Just like they have plans for natural disasters, they have an "#epidemic preparedness" plans.
