China: Reports of bird flu in humans reach 60 - CNN.com - 1 views

  •  
    This is so scary. I am always wary when China says, "Don't worry everything is under control". China was criticized during the SARS outbreak for failing to release information. If bird flu ever gains the ability to spread from human to human, we have a very bad situation.

Could new flu spark global flu pandemic? New bird flu strain seen adapting to mammals, ... - 0 views

  • "The human isolates, but not the avian and environmental ones, have a protein mutation that allows for efficient growth in human cells and that also allows them to grow at a temperature that corresponds to the upper respiratory tract of humans, which is lower than you find in birds,

      These are the same researchers who did the infamous bird flu study that was temporarily banned
  • new virus has sickened at least 33 people, killing nine.

      This is so concerning... and yet it seems that the general population is oblivious to the implications of this virus
  • majority of the viruses in the study -- from both humans and birds -- display mutations in the surface protein hemagglutinin, which the pathogen uses to bind to host cells.
  • The same mutation, Kawaoka notes, lets the avian virus thrive in the cooler temperatures of the human upper respiratory system
  • the new strain could be treated with another clinically relevant antiviral drug, oseltamivir.

WHO: New Flu Passes More Easily from Bird to Human | TIME.com - 0 views

  •  
    H7N9 strain that is capable of spreading quicker than the H5N1 strain. 100 people in China have been affected and killed more than 20. Doesn't immediately cause the noticeable symptoms like most flu strains would, making it difficult to monitor.

The Flu Virus Can Tell Time. Here's Why You Should Care | Popular Science - 0 views

  • Influenza can tell time, and it choreographs its actions according to a strict schedule.
  • The virus has to orchestrate its actions carefully--if it moves too fast, it won’t have time to make new copies of itself, and if it moves too slowly, it might be stopped by immune defenses.
  • To fight it, they tricked the virus into changing the amount of time it took to gather the protein. First, they made it acquire the protein too quickly, which caused the flu to leave the cell before it had made enough copies of itself. In this case, the cells were lung epithelial cells. Then they altered it to leave too late, giving immune cells enough time to respond and kill the virus before it escaped.
  •  
    Viruses are smarter then we ever imagined!! Researchers have realized that virus have their own time-clock. Virus's take about 8 hours to sufficiently make copies and overtake our bodies. They slowly build in our bodies, before the body actually realizes what is happening - by that time it is too late. Researchers are now tricking viruses into changing the time needed to overtake the body - making the body react quicker and kill the virus. The flu vaccine is still the best way, however, if we can fool the time it takes for a virus to overthrow the body - can we stop it in general?

Onions and Flu - Can Raw Onions Prevent the Flu? - Urban Legends - 1 views

  •  
    Although this article does not come from the most scholarly source, my dad and I were talking and he mentioned that if you slice an onion and place it in the corner of the room, it will "absorb" any flu virus present. This is not true.

2 dead in China from unusual bird flu strain - CNN.com - 0 views

  •  
    The article shows a new strain of bird flu H7N9.  The virus has a hard time infecting humans, but for every one human infected there are thousands of birds infected.  This strain is less harmful than H5N1, but still one death has been reported.

A viral grappling hook: Flu virus attacks like a pirate boarding party - 1 views

  •  
    The flu virus carries about 300 to 400 of these hooks and virologists had known that several are needed to fuse the membranes. 4 hooks has recently been identified as the number of hooks required to pull the two membranes together. Without the attachment of 4 hooks the virus is vulnerable to inhibitors which will prevent fusion.

Production of swine flu vaccine is way behind - Yahoo! News - 0 views

  • Also, Protein Sciences Corp. of Meriden, Conn., landed a five-year, $147 million contract to develop a vaccine using its recombinant technology — flu proteins grown in insect cells. The hope is that the first doses would be available within 12 weeks of the beginning of a pandemic. That is about twice as fast as flu vaccine produced from eggs.

Potential novel treatment for influenza discovered: Scientists pursue new therapies as ... - 0 views

  • latest deadly strain of flu, H7N9, is spreading in China -- 82 people in China had been infected with the new strain of flu virus as of April 26, and 17 had died.
  • result of an immune reaction mediated by a protein called Toll-like receptor 4 (TLR4).
  • Currently, vaccines and antiviral medications are the two main approaches to preventing influenza
  •  
    I thought it was interesting that antiviral medications should be administered within two days of infection in order to be effective. This really outlines the need for more effective treatments since this is a very short time frame and there is an increasing resistance to these antiviral therapies in general.

New bird flu show signs of direct jump to humans - 0 views

  •  
    This is the last thing we need! Another strain of bird-to-human transmitted virus, and researcher believe this could be the worst one yet. While research on this virus is still being conducted in China, there is already strong evidence that this could be the next big flu outbreak.

China bird flu cases now at 102 - 0 views

  •  
    It is amazing that in less than a month this new strain has spread to over 100. So far it has only effected China, but I wonder when another country will report a case.

The New Bird Flu, and How to Read the News About It - 0 views

  •  
    It is amazing that twitter is becoming a way for the WHO to inform people if it starts tweeting accurate information. Most time flu's seem to be either over exaggerated by media and many people do not know how to interpret a lot of the information that is being given out by places like the CDC and WHO, causing people to panic.

Swine flu vaccines are safe and time-tested, experts assert -- chicagotribune.com - 0 views

  • "We've been baking this bread for 60 years, and we're pretty good at it, buddy," said Kenneth Alexander, an infectious disease expert at the University of Chicago.
  • "I continue to be amazed that people bring this issue up," said Paul Offit, a pediatrician and noted University of Pennsylvania vaccine researcher. "There have been six exhaustive studies (of a possible link between thimerosal and autism). ... They each came back with a definitive answer: No. Three other studies were done to see if thimerosal caused any signs of mercury poisoning. All three answered: No."
