Community Mitigation Guidelines to Prevent Pandemic Influenza-United States, 2017

Centers for Disease Control and Prevention. 04/21/2017 These guidelines, updated in April 2017, replace the 2007 Interim Pre-pandemic Planning Guidance: Community Strategy for Pandemic Influenza Mitigation in the United States-Early, Targeted, Layered Use of Nonpharmaceutical Interventions (NPIs). Several new elements have been incorporated into the 2017 guidelines, including to support updated recommendations on the use of NPIs, the latest scientific evidence available since the influenza A (H1N1)pdm09 pandemic has been added. A summary of lessons learned from the 2009 H1N1 pandemic response is presented to underscore the importance of broad and flexible pre-pandemic planning. (Text)

Conclusions: The clinical features and outcomes of pandemic (H1N1) 2009 influenza and current circulating seasonal influenza A strains were comparable in hospitalised patients. However, since both seasonal and pandemic influenza can lead to significant morbidity and mortality, the impact of pre-existing seasonal influenza should not be underestimated during the pandemic period.

After the initial identification of the H1N1 pandemic influenza strain in Mexico in April 2009 and its subsequent global spread, several monovalent influenza vaccines were developed as part of the pandemic response. Three of these vaccines, Pandemrix, Arepanrix and Focetria were adjuvanted. One of these, the AS03-adjuvanted Pandemrix vaccine, was primarily used in Europe. Following widespread Pandemrix vaccine administration in Scandinavia, an increased risk of narcolepsy was noted in observational studies. Subsequently, this increased risk was also reported in other European countries as well. In contrast, studies from Ca...

Abstract Avian influenza virus (AIV) is an extraordinarily diverse pathogen that causes significant morbidity in domesticated poultry populations and threatens human life with looming pandemic potential. Controlling avian influenza in susceptible populations requires highly effective, economical and broadly reactive vaccines. Several AIV vaccines have proven insufficient despite their wide use, and better technologies are needed to improve their immunogenicity and broaden effectiveness. Previously, we developed a "mosaic" H5 subtype hemagglutinin (HA) AIV vaccine and demonstrated its broad protection aga...

We describe how CD8+ CTL memory is established following influenza virus infection, and how a robust CTL recall response can lead to more rapid virus elimination by destroying virus-infected cells, and recovery. Exploiting long-term, cross-reactive CTL against the continuously evolving and unpredictable influenza viruses provides a possible mechanism for preventing a disastrous pandemic comparable to the 1918-1919 H1N1 “Spanish flu”, which killed more than 50 million people worldwide.

Abstract The 1918 "Spanish" pandemic is the earliest known influenza H1N1 virus. Since then H1N1 viruses circulated between humans and animals continuously. With the increased amount of samples of H1N1 viruses and technology development, researchers have been studying how the viruses evolved. Here, we analyzed HA and NA genes of H1N1 viruses from three aspects: host distribution, geographical distribution and phylogenetic analysis. The data showed hosts were predominantly human, swine and poultry, and other hosts were mainly cat, ferret, wild bear, canine, cheetah and seal. In terms of geographical distr...

Abstract Swine are reservoirs for anthropogenic/zoonotic influenza viruses, and the prevalence and repeated introduction of the 2009 H1N1 pandemic influenza virus (pdm/09) into pigs raises the possibility of generating novel swine influenza viruses with the potential to infect humans. However, studies aiming to identify miRNAs involved in the transfer of novel swine influenza virus infection to human cells are rare. In this investigation, from the view of small RNA, microarrays and high-throughput sequencing were used to detect differentially expressed miRNAs and mRNAs after human lung epithelial cells were infect...

ConclusionBased on high seroprevalence of antibodies against H1N1 virus during pandemic, vaccination of general population is not recommended. However, high-risk groups and HCWs need to be protected with flu vaccine. There is a need to encourage HCWs for accepting vaccination.

This article summarizes Canada's pandemic public health measures strategy, as described in the recently updated CPIP Public Health Measures Annex. The strategy builds on lessons learned during the 2009 H1N1 pandemic. Key elements of the public health measures strategy include individual measures (e.g. hand hygiene, self-isolation when ill), community-based measures (e.g. school closures, cancellation of mass gatherings), management of cases and close contacts, travel and border-related actions and public education. Factors that influence the effectiveness of public health measures in a pandemic include the pandemic epidemi...
