Little is known about the virological and inflammatory responses of severe pandemic 2009 influenza A(H1N1) virus pneumonia during antiviral treatment. ⋯ In severe 2009 H1N1 pneumonia, viral clearance is slow with treatment, particularly in the lower respiratory tract. A more sustained antiviral regime appears warranted.

[Severe acute respiratory infection in Cuban patients during the influenza A(H1N1) pandemic in Cuba, 2009].
On April 2009, the Mexican health authorities reported increased hospitalization indexes caused by pneumonia with high mortality rates to the Pan-American Health Organization (PAHO). The National Epidemiological Surveillance System of Mexico noticed that this increase mainly occurred in the 20-40 year old population. A new type of swine influenza A (H1N1) virus was identified by laboratory studies as the etiological agent of the first pandemic of the 21st century. On April 26 2009, the National Anti-pandemic Plan was activated by the Cuban Ministry of Public Health, and on May 7th, the lab-confirmed index case appeared. An integrated surveillance system with laboratory confirmation was set up. ⋯ The comprehensive analysis of these results contributes to the national and regional surveillance of respiratory viruses for the improvement of the prevention and control programs of the acute respiratory infections.

Pandemic plans are increasingly attending to groups experiencing health disparities and other social vulnerabilities. Although some pandemic guidance is silent on the issue, guidance that attends to socially vulnerable groups ranges widely, some procedural (often calling for public engagement), and some substantive. Public engagement objectives vary from merely educational to seeking reflective input into the ethical commitments that should guide pandemic planning and response. ⋯ Protecting critical infrastructures on which vulnerable populations and the general public rely; 6. Identifying and removing access barriers during pandemic planning and response; and 7. Collecting and promptly analyzing data during the pandemic to identify groups at disproportionate risk of influenza-related mortality and serious morbidity and to optimize the distribution of resources.

To assess the impact of the 2009 A/H1N1 influenza pandemic in England during the two waves of activity up to end of February 2010 by estimating the probabilities of cases leading to severe events and the proportion of the population infected. ⋯ This study suggests a mild pandemic, characterised by case and infection severity ratios increasing between waves. Results suggest low ascertainment rates, highlighting the importance of systems enabling early robust estimation of severity, to inform optimal public health responses, particularly in light of the apparent resurgence of the 2009 A/H1N1 strain in the 2010-11 influenza season.

Multicenter Study
Pandemic and post-pandemic influenza A (H1N1) infection in critically ill patients.
There is a vast amount of information published regarding the impact of 2009 pandemic Influenza A (pH1N1) virus infection. However, a comparison of risk factors and outcome during the 2010-2011 post-pandemic period has not been described. ⋯ Patients from the post-pandemic Influenza (H1N1)v infection period had an unexpectedly higher mortality rate and showed a trend towards affecting a more vulnerable population, in keeping with more typical seasonal viral infection.
