The 2009 H1N1 influenza pandemic has heightened the interest of clinicians for options in the prevention and management of influenza virus infection in immunocompromised patients. Even before the emergence of the novel 2009 H1N1 strain, influenza disease was a serious complication in patients with hematologic malignancies receiving chemotherapy or undergoing hematopoietic cell transplantation. ...
A novel swine-origin H1N1 influenza A virus has been identified as the cause of the 2009 influenza pandemic in humans. Since then, infections with the pandemic (H1N1) 2009 influenza virus have been documented in a number of animal species. The first known cases of lethal respiratory disease associated with pandemic (H1N1) 2009 influenza virus infection in house pets occurred in domestic cats in...
Asia is considered an important source of influenza A virus (IAV) pandemics, owing to large, diverse viral reservoirs in poultry and swine. However, the zoonotic origins of the 2009 A/H1N1 influenza pandemic virus (pdmH1N1) remain unclear, due to conflicting evidence from swine and humans. There is strong evidence that the first human outbreak of pdmH1N1 occurred in Mexico in early 2009. Howeve...
BACKGROUND In April 2009 a novel influenza A H1N1/2009 virus was identified in Mexico and in the United States which quickly spread around the world. Most of the countries established infection surveillance systems in order to track the number of (laboratory-confirmed) H1N1 cases, hospitalizations and deaths. METHODS The impact of the emergence of the novel pandemic (H1N1) 2009 virus on Frank...
In some adults, infections result from influenza, which usually occurs as respiratory infections. In the central nervous system, influenza can cause aseptic meningitis and encephalitis/encephalopathy syndrome that may cause death or persistent brain complications. This report presents a case of encephalitis/encephalopathy caused by H1N1 virus in a 35-year-old man who was hospitalized with reduc...
BACKGROUND Concerns have been raised about how the transmission of emerging infectious diseases from patients to healthcare workers (HCWs) and vice versa could be recognized and prevented in a timely manner. An effective strategy to block transmission of pandemic H1N1 (2009) influenza in HCWs is important. METHODOLOGY/PRINCIPAL FINDINGS An infection control program was implemented to survey a...
The evolution of classical swine influenza viruses receptor specificity preceding the emergence of the 2009 H1N1 pandemic virus was analyzed in glycan microarrays. Classical swine influenza viruses from the α, β, and γ antigenic clusters isolated between 1945 and 2009 revealed a binding profile very similar to that of 2009 pandemic H1N1 viruses, with selectivity for α2-6-linked sialosides and v...
Reports of a novel influenza virus type A (H1N1), now designated by the World Health Organization as pandemic (H1N1) 2009, emerged from the United States and Mexico in April 2009. The management of the pandemic in Australia required rapid and reliable testing of large numbers of specimens for the novel influenza strain and differentiation from seasonal influenza strains. A real-time reverse tra...
OBJECTIVE To compare the patient characteristics, clinical features and outcomes of adult patients hospitalised with pandemic (H1N1) 2009 influenza and seasonal influenza. DESIGN AND SETTING Retrospective medical record review of all patients admitted to Liverpool Hospital, Sydney, with laboratory-confirmed influenza from the initiation of the "PROTECT" phase of the pandemic response on 17 Ju...
Novel influenza A (H1N1) virus infection continues to cause illness and death among persons worldwide. Immunosuppressed patients with influenza virus infection can shed virus for prolonged periods, increasing the chances for development of drug resistance. On August 6, 2009, CDC detected evidence of resistance to the antiviral medication oseltamivir in two severely immunosuppressed patients wit...
