Canadian pandemic influenza preparedness: Public health measures strategy.

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 epidemiology, timing of implementation, how the measures are used (i.e. alone or in combination), the scalability and flexibility of public compliance. The CPIP is an evergreen guidance document and the Annex will be updated as new information warrants. PMID: 31285708 [PubMed]

Conclusions: Human challenge studies and systems biology approaches are important tools that should be used in concert to advance our understanding of influenza infection and provide targets for novel therapeutics and immunizations. Introduction Although influenza virus was recognized as an important pathogen over a century ago, influenza continues to cause a significant burden of disease. In the United States alone, it's estimated that in the 2017–2018 season there were 959,000 hospitalizations related to influenza illness, and 79,400 deaths (CDC, 2018). Worldwide, WHO estimates that annual influenza...

The flu season is up and running in the Northern Hemisphere, and early signs in both the United States and Europe are that the effects might not be quite as severe as the brutal 2017/18 season. The United States is predominantly seeing H1N1 circulating, while monitoring in Europe has identified co-circulation of H1N1 and H3N2—both varieties of Influenza A that should be covered by the seasonable vaccine. What if they weren’t though? Influenza A can be found in both human and animal populations, and it evolves rapidly through genetic mutation. Each year many humans rely on their country&a...

Influenza has been impacting public health on a global scale since the beginning of recorded history. Influenza, also known as the “flu,” has numerous organizations committed to public health research, developing vaccines, and educating on best practices to prepare for the upcoming flu season. By gaining an understanding of the flu through history, virology, and how it impacts our society, we can have a better appreciation for the commitment that’s involved with combating the flu. What Is Influenza (and What’s Not)? The eyes of an epidemiologist can twitch for a variety of reasons, one of them being...

CONCLUSION: Common themes have emerged from the Canadian literature addressing barriers and facilitators of vaccination during pregnancy. However, there is a paucity of literature to suggest strategies to improve the uptake of vaccination during pregnancy in Canadian settings. Further research is urgently needed given the expanding role of vaccination during routine prenatal care. PMID: 30361161 [PubMed - as supplied by publisher]

Abstract The limited protection of current commerical vaccines necessitates the investigation of novel vaccine strategies for unpredictable outbreaks. To investigate the feasibility of using vaccines derived from Group 1 influenza A virus to induce broadly cross-reactive immune responses against multiple influenza subtypes, we tested a panel of sequential 4-dose immunization regimens in mice. Mice were treated with inactivated (seasonal H1N1, pandemic H1N1 and H5N1) and vaccinia virus-based H5N1 live-attenuated vaccines in different combinations. Mice were then challenged by viruses of either Group 1 (H1N1) or Gro...

Introduction Following the initial outbreak of A/H1N1pdm09 in 2009-10, periodic resurgences of the pandemic influenza virus have been reported from India with variable morbidity and mortality. 1, 2 We have earlier reported a recrudescence of A/H1N1pdm09 in 2012-13 in Kashmir region of the northern Indian state of Jammu and Kashmir where influenza is an important cause of acute respiratory infections during the winter months. 3, 4 During the initial months of 2015, an unusual increase in influenza A/H1N1pdm09 activity was observed thoughout India with more than 39000 cases and about 3000 deaths. 5 While the activity was us...

In this study, we attempted to generate a high growth influenza vaccine strain in MDCK cells using an A/Puerto/8/1934 (H1N1) vaccine seed strain. Following 48 serial passages with four rounds of virus plaque purification in MDCK cells, we were able to select several MDCK-adapted plaques that could grow over 108 PFU/ml. Genetic characterization revealed that these viruses mainly had amino acid substitutions in internal genes and exhibited higher polymerase activities. By using of a series of Rg viruses, we demonstrated the essential residues of each gene and identified a set of high-growth strains in MDCK cells (PB1D153N, M...

Abstract Pandemic influenza A (H1N1) 2009 virus was first detected in India in May 2009 which subsequently became endemic in many parts of the country. Influenza A viruses have the ability to evade the immune response through its ability of antigenic variations. The study aims to characterize influenza A (H1N1) pdm 09 viruses circulating in Mumbai during the pandemic and post-pandemic period. Nasopharyngeal swabs positive for influenza A (H1N1) pdm 09 viruses were inoculated on Madin-Darby canine kidney cell line for virus isolation. Molecular and phylogenetic analysis of influenza A (H1N1) pdm 09 isolates was con...

Editor’s Note: This post reflects on a speech on pandemic preparedness Dr. Fauci gave on January 10, 2017 in Washington, DC, hosted by  The Center for Global Health Science and Security at Georgetown University Medical Center, the Harvard Global Health Institute, and Health Affairs. One of the most important challenges facing the new Administration is preparedness for the pandemic outbreak of an infectious disease. Infectious diseases will continue to pose a significant threat to public health and the economies of countries worldwide. The U.S. government will need to continue its investment to combat these ...
