Researchers at Fred Hutch Cancer Institute have found that the flu viruses primarily found in children (such as H1N1) circulate much slower than those strains found in jet setting adults (H3N2). This study is the first large scale attempt to track the H1N1 virus, and influenza B strains OR as it turns out the much faster traveling H3N2 (and is published over at Nature).
The transmission of flu seems to mirror our own behavior! And it makes a case for why we should really be paying attention to India. Read about it over at Hutch News.
