Latest Pandemic H1N1/09 virus Stories

2013-04-04 10:25:19

Significant investments over the past decade into disease surveillance and notification systems appear to have "paid off" and the systems "work remarkably well," says a Georgetown University Medical Center researcher who examined the public health response systems during the 2009 H1N1 influenza pandemic. The findings are published online today in PLOS ONE. After the Sept. 11 terrorist attacks in the U.S. and the potential threat of bioterrorism, many new advanced systems for disease...

Twitter Algorithm Can Track Flu Outbreaks
2013-01-29 09:44:34

[ Watch the Video: Twitter Stories: The Future of Public Health ] Brett Smith for redOrbit.com - Your Universe Online Is it an epic timewaster or a new way to take society´s pulse, literally? Computer scientists from around the world have devised algorithms that parse Twitter posts for all kinds of insight and a new one from Johns Hopkins University is showing promising results for tracking the spread of the flu virus across the United States. To track the flu via Twitter,...

One In Five People Infected During 2009 H1N1 Flu Pandemic
2013-01-25 13:00:32

Lee Rannals for redOrbit.com — Your Universe Online A new study shows that at least one in five people in countries including India, Australia and the U.K. were infected with influenza during the first year of the 2009 H1N1 pandemic. Forty-seven percent of those infected were aged between five and 19, researchers said. Older people were less likely to have become infected, with eleven percent of people over the age of 65 becoming infected. They wrote in the journal Influenza...

Elusive Replication Machinery Of Flu Viruses Described
2012-11-23 09:27:03

Scripps Research Institute Scientists at The Scripps Research Institute (TSRI) have made a major advance in understanding how flu viruses replicate within infected cells. The researchers used cutting-edge molecular biology and electron-microscopy techniques to "see" one of influenza's essential protein complexes in unprecedented detail. The images generated in the study show flu virus proteins in the act of self-replication, highlighting the virus's vulnerabilities that are sure to be of...

Mathematicians have developed a powerful tool to quantify the spread and infectiousness of viruses like the pandemic H1N1 flu strain, which can be used together with modern laboratory techniques to help the healthcare system plan its response to disease outbreaks. By putting statistical data under the microscope, University of Warwick researchers have created a model to predict the impact of future pandemics in real-time as they strike. During the 2009 outbreak, the true extent of H1N1...

A new model of influenza transmission, published in BioMed Central's open access journal BMC Medicine, using more detailed information about patterns and severity of infection than previous models, finds that cases and transmission rates of H1N1 during the 2009-2010 flu pandemic have been underestimated. This model can provide a more robust and accurate real-time estimate of infection during a pandemic, which will help health services prepare and respond to future outbreaks. During an...

Lee Rannals for redOrbit.com — Your Universe Online You may have contracted the flu, and already passed it on to your neighbors, before you ever started showing symptoms, according to a new study. Researchers found while examining influenza transmission in ferrets that the virus can actually be passed on to someone else before the symptoms occur. Knowing whether someone is infectious before symptoms occur is important to try and help authorities stop an epidemic. Previous...

Swine Flu Spreading Through Contact With Infected Animals At Fairs
2012-08-09 09:27:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Experts at the Centers for Disease Control and Prevention (CDC) have warned that anyone attending state fairs this year should use caution when visiting pig enclosures due to a new strain of swine flu that is passing from mammals to humans. Initial reports stated that 29 cases of the new strain had affected people since the beginning of the year. But in the past week more than 30 cases have been reported in Ohio alone, all from...

2009 Swine Flu Pandemic Death Toll Much Worse Than Originally Believed
2012-06-26 12:02:29

Lawrence LeBlond for redOrbit.com Shortly after the 2009 H1N1 “swine flu” pandemic, health experts from the World Health Organization (WHO) had reported that roughly 18,500 people died from the virus, a finding that is being called into question as researchers now believe the death toll reached more than quarter of a million people, 15 times more than the original estimate. Publishing their findings in The Lancet Infectious Diseases journal, an international group of...

Getting a flu shot during pregnancy provides unanticipated benefits to the baby, according to the authors of a large population-based study examining the issue. Specifically, the study showed that H1N1 vaccination during the pandemic was associated with a significantly reduced risk of stillbirth, preterm birth and extremely small babies at birth. Researchers at the Ottawa Hospital Research Institute (OHRI), the CHEO Research Institute and the University of Ottawa (uOttawa) used data from...
