'Barcoding' viruses could help detect mutated strains

The influenza A virus ranks among our planet's least-controlled pathogens, resulting in seasonal epidemics and even global pandemics. The H1N1 virus of 2009 -- a new type of influenza A virus -- caused the first influenza pandemic in more than 40 years, according to the Centers for Disease Control and Prevention.

But despite the fast and furious spread of H1N1 that year, it turned out to affect the lungs much in the way the seasonal flu does. Using a new type of test developed at the University of Leeds "might have been a way to identify how lethal … Read more

Close the airports! The disease is spreading...

Pandemic for iOS is a faithful recreation of the popular Web-based game where the object is to play as a villain and infect our entire planet with an evolving disease. The game is obviously quite morbid, but it's also extremely addictive as you start with one infected person in a random location and try to spread a disease to every corner of the globe. You can choose from three skill levels at the beginning of the game, with the easiest setting for quick sessions allowing for more experimentation, and the hardest setting making it a real challenge to even … Read more

Princeton researchers use satellite images to track disease

Tracking where humans migrate and cluster in any given country from season to season is, in some places, a tall order. Which makes tracking the risk of infectious disease outbreaks that thrive in dense populations tricky as well.

Satellite images of nighttime lights could be the answer, according to researchers at Princeton, who report on their findings today in the journal Science.

Using nighttime images taken of Niger's three largest cities between 2000 and 2004 by a U.S. Department of Defense satellite, and checking those images against public health records compiled by Niger's Ministry of Health, they … Read more

Computer model predicts severity of flu outbreaks

Scientists at the National Institutes of Health said yesterday they have come up with a computer model they say can predict infection rates of the influenza virus, and it could help people gird up for flu season in the future.

It has been well established in the scientific community that the extent to which a flu virus spreads in a given year is related to how much it has mutated from previous seasons. But these scientists set out to translate that knowledge into something more concrete.

The group looked specifically at data on virus genetics and infection rates from 16 … Read more

Virus spreads across Google Earth, virtually

Biomedical researchers wanted to get a good look at the avian flu virus. And they did not turn to a super microscope. They used Google Earth instead. With Keyhole Markup Language on Google Earth scientists were able to trace the course of the disease over the past decade.

The Google Earth project animates the spread of avian flu virus. In addition the data contains information on all known strains of the evolving flu virus plus all its host organisms. So far avian flu has not proven highly contagious among humans with fewer than 300 known cases worldwide. However, medical research … Read more
