Detecting transmissibility of avian influenza virus in human households
... from animals in humans is therefore key for early detection
of epidemic spread, and for effective control. In a study published in PLoS Computational Biology, the authors from the Netherlands and the United Kingdom have used data from a small but well-defined study of H7N7 avian influenza virus transmission i...
