The novel pandemic influenza A/H1N1v has also led to a rapid increase in the number of new cases in Germany. In the majority of patients the disease has taken a mild clinical course. However, in isolated cases severe complications requiring hospitalization or intensive care treatment have occurred. ⋯ Treatment decisions should not be delayed to await laboratory confirmation in these patients as early initiation of antiviral therapy is recommended. Elements of supportive care depend on the presentation of complications and secondary organ failure. If rapidly progressive lung dysfunction occurs, refractory to routine mechanical ventilation, early reporting to centers experienced in the use of extracorporeal membrane oxygenation (ECMO) should be established.

ReviewThe 2009 influenza A (H1N1) pandemic: what have we learned in the past 6 months.
The present review describes how the first influenza pandemic of the XXI century occurred, the characteristics of the virus that produced it, its epidemiology, clinical and pathological presentation, and the treatment and prevention methods that have been instituted. The lessons that have been learned in the first 6 months of the pandemic include: 1) predictions were not fulfilled (it was not an avian virus but a swine virus that caused the pandemic, it started in the American continent not in Asia), 2) international cooperation was critical, 3) mass media played a key role communicating to the public and health care professionals about this evolving, and 4) preparedness plans were very important to confront the pandemic.

The ongoing pandemic of 2009 H1N1 swine-origin influenza A has heightened the world's attention to the reality of influenza pandemics and their unpredictable nature. Currently, the 2009 H1N1 influenza strain appears to cause mild clinical disease for the majority of those infected. However, the risk of severe disease from this strain or other future strains remains an ongoing concern and is noted in specific patient populations. ⋯ Triage algorithms for resource allocation have been delineated in the general medical population. However, no current guidance considers the unique aspects of pregnant women and their unborn fetuses. An approach is suggested that may help guide facilities faced with these challenges.

The 2009 H1N1 influenza virus (formerly known as swine flu) first appeared in Mexico and the United States in March and April 2009 and has swept the globe with unprecedented speed as a result of airline travel. On June 11, 2009, the World Health Organization raised its pandemic level to the highest level, Phase 6, indicating widespread community transmission on at least two continents. The 2009 H1N1 virus contains a unique combination of gene segments from human, swine and avian influenza A viruses. ⋯ Bacterial co-infection has played a significant role in fatal cases. The case of fatality has been estimated at around 0.4%. Mathematical modeling suggests that the effect of novel influenza virus can be reduced by immunization, but the question remains: can we produce enough H1N1 vaccine to beat the pandemic?

From the first case reports of pandemic influenza (H1N1) 2009 it was clear that a significant proportion of infected individuals suffered a primary viral pneumonia. The objective of this study was twofold; to assess the utility of the CURB-65 community acquired pneumonia (CAP) severity index in predicting pneumonia severity and ICU admission, and to assess the relative sensitivity of nasopharyngeal versus lower respiratory tract sampling for the detection of pandemic influenza (H1N1) CAP. ⋯ The CURB-65 score does not predict severe pandemic influenza (H1N1) 2009 CAP or need for ICU admission. Lower respiratory tract specimens should be collected when pandemic (H1N1) 2009 influenza CAP is suspected.
