From the Summary: "On June 11, in response to the global spread of a new strain of influenza, the World Health Organization (WHO) raised the level of influenza pandemic alert to phase 6, the highest level, which indicates the start of an actual pandemic. This change in alert level reflected the spread of the new virus, not its severity. In late April 2009, human cases of infection with a novel influenza A(H1N1) virus were identified. Since then, the virus has become widespread. Although currently the pandemic is of moderate severity with the majority of patients experiencing mild symptoms and making a rapid and full recovery, the virus and its effects may change over time. This report provides a brief overview of selected legal issues including emergency measures, civil rights, liability issues, and employment issues."
