There's not a huge amount of detail in the new There's no sign this new virus has taken off or spread in the regions of China where it was found. No states reported widespread influenza activity during the weeks ending April 21May 19, 2007 (weeks 16-20). Please update this article to reflect recent events or newly available information. This will allow it to In the southern hemisphere, where it is winter, swine flu apparently Four major vaccine manufacturers report that their swine flu vaccines As autumn arrives in the northern hemisphere, experts are on tenterhooks: a particular worry is that swine flu Vaccination programmes begin in the US and Europe, but many healthcare workers are Production delays also continue to plague the deployment of vaccine. If the swine flu mutates, scientists aren't sure how effective a vaccine made now from the current strain will remain. “Swine Flu” The US Centre for Disease and Control Prevention (CDC) estimated that 150, 000 to 575,000 people died from (H1N1) pandemic virus infection in the first year of the outbreak. Timing of peak activity varied across the nine surveillance regions. Of the 53 cases 6 months of age and older for whom the vaccination status was known, 50 (94%) were not vaccinated against influenza. agricultural fairs, farms, or petting zoos). People born after the 1957 pandemic do not have this immunity.An H3N2 virus causes the “Hong Kong” flu pandemic, which is even milder than the Asian flu, killing an estimated 0.75 million to 1 million people worldwide.The virus only differs from H2N2 in one of its surface proteins, the H; since many people still have antibodies to the unchanged N2 protein, its effects are less severe. Presumptive Democratic presidential nominee Joe Biden has talked up the Obama administration’s handling of the 2009 swine flu pandemic that he … The peak percentage of specimens testing positive for influenza during the previous three seasons has ranged from 22.6% to 34.7% and occurred during early December to early March. So far it's looking like it's not that serious. The “Spanish flu” epidemic of 1918 kills at least 50 million people worldwide. Toward the end of June 2009, the number of deaths related to the virus in the US surpassed those of all other countries as well. Most humans don't already have antibodies to the G4 viruses meaning most people's immune systems don't have the necessary tools to prevent disease if they get infected by a G4 virus.In summary, this virus has been around a few years, we know it can jump from pigs to humans and it ticks all the boxes to be what infectious disease scholars call a PPP — a potential pandemic pathogen.We don't have much evidence to work with yet but it's likely people who got these infections in the past didn't find it too memorable. European scientists start organising to However, Indonesia, where most H5N1 outbreaks are happening, But worries about H5N1 subside as it fails to become contagious in people – although virologists continue to warn that it is not the only threatening flu virus out there. Scientists said the virus was already spreading widely among people, and, in fact, was more common in humans than in pigs, so humans were more likely to catch it from others than from pigs.In mid-October, it was reported that flu caused by the H1N1 virus was widespread in 41 states, and flu-like illnesses accounted for 6.1 percent of all doctor visits, which was considered highProjections of the supply of H1N1 vaccine had decreased significantly from a level of 120 million doses ready in October, estimated during the summer, to an estimate of 28 to 30 million doses by the end of the month. The swine flu virus, H1N1, may have killed 15 times the number of people counted by the World Health Organization, according to a new study from the CDC. They keep track of bird, human and swine flus because, as the researchers note in their paper, "systematic surveillance of influenza viruses in pigs is essential for early warning and preparedness for the next potential pandemic.In their influenza virus surveillance of pigs from 2011 to 2018, the researchers found what they called "a recently emerged genotype 4 (G4) reassortant Eurasian avian-like (EA) H1N1 virus." Of these, 18,817 (79.2%) were influenza A viruses and 4,936 (20.8%) were influenza B viruses.
