EurekAlert -- Each year 3-5 million people have severe cases and 250-500,000 die from complications of seasonal influenza world-wide. This year, the novel 2009 H1N1 (nH1N1) influenza, previously called swine flu, has reached pandemic status. Since novel 2009 H1N1 is a viral infection of the respiratory tract, there are additional challenges for cardiopulmonary transplant recipients and donors, as well as for the healthcare workers involved in the transplant process. In an article published online today in the Journal of Heart and Lung Transplantation (www.jhltonline.org), physicians representing the International Society for Heart & Lung Transplantation (ISHLT) Infectious Disease Council issue an advisory for all programs in cardiothoracic transplantation.
