    On Friday, one of the world’s most senior epidemiologists, Professor Johan Giesecke, sat down with UnHeard and discussed lockdown policies across the globe, and what he perceives as the policies’ weaknesses in tackling the China-originated novel coronavirus, COVID-19. Professor Giesecke currently serves as an advisor to the Swedish Government, was the first Chief Scientist of the European Centre for Disease Prevention and Control (CDC), and a former advisor to the director general of the WHO (he’s now retired and serves as an advisor to the WHO only in an honorary capacity). “The measures we should take against the pandemic should...

    Knut M. Wittkowski is a professor of epidemiology and biostatistics and research design at Rockefeller University in New York for over 20 years. He is a proven expert in modeling epidemics. He made a first determination in the 1980s, when he denied the danger of an HIV epidemic in the heterosexual population - and was right. In the current debate about SARS-CORONA VIRUS-2, Professor Wittkowski is now declaring, based on data from the registration authorities and on experience with dealing with respiratory diseases, that the epidemic has already passed its peak. The following interview was translated from German to English...

    I offer this not to encourage complacency, of which there’s already been far too much, but as a purgative after feeding you a horse-sized dose of hopelessness this morning.John Ioannidis is a respected epidemiologist at Stanford. His specialty is “metascience,” i.e. calling BS on shoddy medical research. The point of this new piece isn’t to declare that the data on coronavirus is shoddy; the point is to declare that we just don’t have enough of it yet to feel confident about how dangerous the disease is. And that matters a lot when you’re implementing policies with massive social repercussions...
  • Cryptic transmission of novel coronavirus SARS-CoV-2 revealed by genomic epidemiology

    The field of genomic epidemiology focuses on using the genetic sequences of pathogens to understand patterns of transmission and spread. Viruses mutate very quickly and accumulate changes during the process of transmission from one infected individual to another. The novel coronavirus SARS-CoV-2 which is responsible for the emerging COVID-19 pandemic mutates at an average of about two mutations per month. After someone is exposed they will generally incubate the virus for ~5 days before symptoms develop and transmission occurs. Other research has shown that the "serial interval" of SARS-CoV-2 is ~7 days. You can think of a transmission chain as...
  • Plague in humans 'twice as old' but didn't begin as flea-borne, ancient DNA reveals

    EurekAlert! ^ | October 22, 2015 | University of Cambridge
    New research using ancient DNA has revealed that plague has been endemic in human populations for more than twice as long as previously thought, and that the ancestral plague would have been predominantly spread by human-to-human contact -- until genetic mutations allowed Yersinia pestis (Y. pestis), the bacteria that causes plague, to survive in the gut of fleas. These mutations, which may have occurred near the turn of the 1st millennium BC, gave rise to the bubonic form of plague that spreads at terrifying speed through flea -- and consequently rat -- carriers. The bubonic plague caused the pandemics that...

The federal committee responsible for nutrition guidelines (the Dietary Guidelines Advisory Committee, or DGAC) has finally issued a 571-page report of recommendations that calls for:  the adoption of “plant-based” diets, taxes on dessert, trained obesity “interventionists” at worksites, and electronic monitoring of how long Americans sit in front of the television.

    Surviving a Zombie Apocalypse: Just Do the Math This equation could spell your doom: (bN)(S/N)Z = bSZ. That is, if you ever found yourself in the midst of a zombie pandemic. That's because the calculation describes the rate of zombie transmission, from one walking dead individual to many, according to its creators, Robert J. Smith?, a mathematics professor at the University of Ottawa who spells his name with a "?" at the end, and his students. Smith's work has inspired other researchers to create zombie mathematical models, which will be published with Smith's work in the upcoming book, "Mathematical Modeling...

    The Ebola virus can spread through the air from pigs to macaques, a new study suggests. Transmission of the virus — which causes an often fatal hemorrhagic fever in people and primates — was thought to require direct contact with body fluids from an infected animal or person. But in the new study, published online November 15 in Scientific Reports, piglets infected with Ebola passed the virus to macaques housed in the same room even though the animals never touched. “The evidence that the virus got from a pig to a monkey through a respiratory route is good,” says Glenn...

    The Virus that Inspired the Whole Zombie Genre Zombies have come to dominate pop culture — and the explanations for their origins range from dark magic to strange satellites. But the concept of zombies has been around for thousands of years — and it looks like the idea originally came from the world of epidemiology, not the world of legends. Biting, fear of light, speechlessness, and the intense aggression that most zombie movies display all come from a single source; rabies. Take a look at the original "rage virus." While some zombie movies go for the uncanny — emphasizing the...

    Enlarge Image An advisory committee that met yesterday to consider the design of the struggling National Children's Study (NCS) came down firmly in favor of one option: The study should recruit children from a geographic sample that represents the entire U.S. population. But whether the National Institutes of Health (NIH) will go with that plan isn't yet clear. Proposed by Congress 12 years ago, NCS aims to enroll 100,000 pregnant women and follow their babies' health from before birth to age 21. In February, NIH announced that because the original plan to recruit women from certain addresses in 105...

    (English-language translation) A septuagenarian missionary became the first person to import the dangerous cholera bacterium to Puerto Rico in over a century. Confirmation was done by the Department of Health, following protocol which requires that confirmed cholera cases be reported within 24 hours. The man, whom the Department of Health only identified as a missionary who lives in the northern part of the island, traveled to the Dominican Republic two weeks ago to do work in an area where hygienic conditions were not the best. "He is a person who travels to the Dominican Republic frequently," State Epidemiologist Carmen Deseda...

    White people in the United States die of drug overdoses more often than other ethnic groups. Black people are hit proportionately harder by AIDS, strokes and heart disease. And American Indians are more likely to die in car crashes. To shed more light on the ills of America’s poor — and occasionally its rich — the Centers for Disease Control and Prevention on Thursday released its first report detailing racial disparities in a broad array of health problems. While some are well known, others have had little attention; there were also a few surprises. The agency did not delve into...

    After five years of lying low, Legionnaire's disease - a potentially fatal lung infection - returned to the small city of Alcoi, Spain, on July 21, 2009. > This microbe lives in fresh water nearly everywhere, and it becomes a problem only when inhaled as a fine spray or aerosol. (Legionella is harmless if you drink it.) Outbreaks are usually traced back to man-made supplies of warm water, such as water cooling systems, fountains, hot tubs, even showers. > Investigations into Legionella outbreaks are difficult, according to Dr. Lauri Hicks, a medical epidemiologist in the respiratory-diseases branch of the Centers...

    Beware of Gonorrhea Lectim The Center for Disease Control has issued a warning about a new virulent strain of Sexually Transmitted Disease. The disease is contracted through dangerous and high-risk behavior, especially in areas high in polling places. The disease is called “Gonorrhea Lectim”. And pronounced "gonna re-elect ‘em." Many victims showed symptoms of it in 2008. Yet after having been screwed repeatedly during the past year or so Naturalists and Epidemiologists are amazed at how destructive this disease has become since it is readily apparent to most of the general public but not reported in the liberal media. However,...

    QUEENSLAND researchers believe they have found a way to to control the spread of dengue fever, which afflicts more than 50 million people worldwide every year. The team at the University of Queensland's (UQ) School of Biological Sciences, led by Professor Scott O'Neill, is investigating infecting mosquitoes that transmit dengue fever with a bacterium that shortens their lifespan, limiting their ability to infect humans with the dengue virus. Professor O'Neill said this approach may be even more effective than first thought. "In a surprising development we have found that mosquitoes carrying this bacterium - known as Wolbachia - are resistant...

    Abstract The epidemiology of influenza swarms with incongruities, incongruities exhaustively detailed by the late British epidemiologist...propose a parsimonious theory explaining why influenza is, ..."seemingly unmindful of traditional infectious disease behavioral patterns." Recent discoveries indicate vitamin D upregulates the endogenous antibiotics of innate immunity and suggest that the incongruities explored by Hope-Simpson may be secondary to the epidemiology of vitamin D deficiency. We identify – and attempt to explain – nine influenza conundrums: (1) Why is influenza both seasonal and ubiquitous and where is the virus between epidemics? (2) Why are the epidemics so explosive? (3) Why do they end so...
