Swine Flu Update

Cliff Notes for “Swine flu: One Killer virus, three key questions.”

swine flu virusBy Ilene

Brendan Maher and Declan Butler, authors of a recently published Nature article “Swine flu: One killer virus, three key questions,” set out to answer three questions about the H1N1 virus. Here’s what they found. 

How does it kill?

Sherif Zaki, head of the infectious-disease pathology branch at the Centers for Disease Control, discusses his team’s observations from their pathological studies.    

1.  The H1N1 virus penetrates deep into the alveoli (the terminal air sacs in the lungs). In contrast, the seasonal flu viruses tend to infect cells higher in the upper airways. This deep penetration is reminiscent of the action of the H5N1 avian flu virus. Zaki commented: “[H1N1] is like avian flu on steroids.”  Why might this be?

Zaki says that his observations fit well with recent research looking at the mechanism of infection. A group led by Mikhail Matrosovich at Philipps University Marburg in Germany and Ten Feizi at Imperial College London studied sialyl glycans, glycoproteins that the flu virus binds to in order to gain entry to human cells. Although seasonal strains of H1N1 bind mostly to versions of the glycoproteins known as α2-6, the researchers found that the new pandemic H1N1 can also bind to a version called α2-3, which is found in greater proportion in the lower respiratory tract.

2.  In patients who have died, co-infection was common with H1N1.  Zaki’s group observed infection with bacteria such as Staph aureus or Streptococcus pneumoniae in about a third of the fatal swine-flu cases. However, in the remaining two thirds of fatal cases, the virus was lethal alone.  The damage seen in the lungs is characterized as ‘diffuse alveolar damage,’ reflecting a very difficult to treat state of respiratory distress syndrome. According to Zaki’s research, about 90% of the fatal cases had some underlying medical condition.

Zaki expects the number of flu cases to increase as the flu season “ramps up.”

How does H1N1 spread?

Brendan Maher visited Peter Palese’s laboratory at Mount Sinai School of Medicine where testing for how the viruses spread is being carried out. Researchers John Steel and Anice Lowen compared the transmissibility of H1N1 to that of seasonal flu using a guinea pig model. Their data indicate that the H1N1 virus transmits as efficiently as seasonal flu viruses, which is consistent with real-world data showing…

For Bonds, This Is Now The Second Worst Bear Market In 40 Years

Courtesy of ZeroHedge View original post here.

Last December, we predicted that the US was heading for a "titanic taper tantrum" in 2021, to an extent as a result of a sharp drop in bond demand as a result of reduced bond purchases by the Fed but also due to a spike in inflation which would lead to a sharp drop in demand for duration.

So fast forward to this week when the crash in US Treasurys, and especially the belly of the curve led by a plunge in 5Y prices...

There's A "Chip" Shortage: And TSM Holds All The Cards

By Mauldin Economics. Originally published at ValueWalk.

“You drove 1,000 miles just for this game?” Christmas 1988 was a stressful time for many American parents. Nintendo’s Super Mario Bros. 2 was the must-have toy that year. But copies of the hit videogame were as scarce as hen’s teeth.

ABC News ran a 20/20 special on the shortage called “Nuts for Nintendo.” They chatted to one dad who drove 1,000 miles from Indiana to NYC in the hopes of grabbing a copy.

Is Rising Inflation About To Hit U.S. Economy In Big Way?

Inflation seems to be a thing of the past… but current trading in bond and commodity markets tell us that it could become a thing of the future!

Inflation hasn’t been an issue, or even on our radar, since the 1980s. Sure, the 2007 surge in oil prices offered some concern but the financial crisis killed any thoughts of inflation.

So what’s got us concerned about inflation in 2021?

Today we take a look at long-term charts of two potential inflation indicators: Crude Oil ...

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
