Experts keep an eye on new strains of flu

It’s flu season, and public health officials and infectious disease experts at the University of California-San Francisco are paying close attention to new strains of influenza. They’re concerned with a new strain of avian flu that could mutate and become more easily transmitted. Currently, to contract avian flu, you have to have direct contact with an infected bird; the disease isn’t able to be transmitted between people. The experts are also keeping an eye on new, drug-resistant strains of flu reported in Australia during the flu season there.

Genetically engineered, highly contagious strain of H5N1 causes controversy

Scientists at the University of Wisconsin-Madison and Erasmus Medical Center in the Netherlands, working independently, have found a way to genetically engineer H5N1, the avian bird flu, to make it highly contagious to humans. Ron Fouchier, the Dutch scientist, created the virus in a lab and then infected ferrets, which transmit diseases to each other similar to the way humans do. (A ferret infected with the virus could cause another ferret housed in the same cage to get sick simply by being nearby.)

One Health Headlines: Friday, October 21, 2011

I spend so much time scanning the news and searching for One Health stories that it’s always a nice surprise when those stories come to me. That was the case earlier this week, when, upon turning on the radio, I heard microbiologist Nathan Wolfe being interviewed and discussing his work studying how viruses emerge from animals into human populations around the world.
