BACKGROUND The 2009 swine-origin influenza virus (S-OIV) H1N1 pandemic has caused more than 18,000 deaths worldwide. Vaccines against the 2009 A/H1N1 influenza virus are useful for preventing infection and controlling the pandemic. The kinetics of the immune response following vaccination with the 2009 A/H1N1 influenza vaccine need further investigation. METHODOLOGY/PRINCIPAL FINDINGS 58 volu...
background pandemic flu is a concerning problem with potentially high mortality and morbidity rates, so needs a proper health system response in each country. objectives to evaluate the nationwide health system response in iran after declaration of h1n1/swine flu pandemic in june 2009. patients and methods a surveillance system in all regions of country was implemented upon declaration of pande...
The pandemic novel influenza A (H1N1) infection was considered widespread in Brazil on July, 2009. Since then, 9.249 cases were confirmed in Brazil, most of them concentrated in São Paulo. The Hospital das Clínicas of the University of São Paulo is a reference center for H1N1 cases in São Paulo. The purpose of this review is to analyze the evidence concerning diagnosis, prevention, and treatmen...
Recent outbreaks of H5, H7, and H9 influenza A viruses in humans have served as a vivid reminder of the potentially devastating effects that a novel pandemic could exert on the modern world. Those who have survived infections with influenza viruses in the past have been protected from subsequent antigenically similar pandemics through adaptive immunity. For example, during the 2009 H1N1 "swine ...
Influenza A (H1N1) viruses of swine origin were introduced into the human population in 2009 and caused a pandemic. The disease burden in the elderly was relatively low, which was attributed to the presence of cross-reacting serum antibodies in this age group, which were raised against seasonal influenza A (H1N1) viruses that circulated before 1957. It has also been described how infection with...
results out of 253 cases confirmed for influenza a (h1n1), 9 women and 11men had died. amongst these cases the minimum and maximum age was3.5 and90 years, respectively. also, from the 20 confirmed cases of influenza a (h1n1) that had died, 16 cases had at least one underlying disease. conclusions there was no significant association between mortality of confirmed cases of influenza a (h1n1) and...
We describe the epidemiology of influenza virus infections in refugees in a camp in rural Southeast Asia during May-October 2009, the first 6 months after identification of pandemic (H1N1) 2009 in Thailand. Influenza A viruses were detected in 20% of patients who had influenza-like illness and in 23% of those who had clinical pneumonia. Seasonal influenza A (H1N1) was the predominant virus circ...
BACKGROUND The 2008-09 influenza season was the time in which the Department of Veterans Affairs (VA) utilized an electronic biosurveillance system for tracking and monitoring of influenza trends. The system, known as ESSENCE or Electronic Surveillance System for the Early Notification of Community-based Epidemics, was monitored for the influenza season as well as for a rise in influenza cases ...
Influenza is a respiratory tract infection, causing pandemic outbreaks. Spanish flu (A/H1N1), a pandemic occurred between 1918 and 1919, tolled patients and fatalities of 500 million and 50 million, respectively. Recently, human infection with highly pathogenic avian influenza A/H5N1 and swine influenza [Pandemic (H1N1) 2009] was reported. Because of the population explosion and busy global air...
Purpose. To provide an overview of the 2009 H1N1 influenza pandemic and antiviral treatment options for influenza. Summary. Influenza infection causes significant morbidity and mortality every year. The high mutation rate and segmented nature of influenza virus genome gives rise to high genetic variability which enables the virus to escape antiviral and vaccine interventions. A novel H1N1 strai...
