Recent research of Taubenberger et al. has suggested that the 1918 virus, like H5N1, could have arisen directly from an avian influenza virus. [19] However, researchers at University of Virginia and Australian National University have suggested that there may be an alternative interpretation of the data used in the Taubenberger et al. paper.
Despite the high morbidity and mortality rates that resulted from the epidemic, the Spanish flu began to fade from public awareness over the decades until the arrival of news about bird flu and other pandemics in the 1990s and 2000s. [316] [317] This has led some historians to label the Spanish flu a "forgotten pandemic". [173]
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
Changing strains of influenza mean predicting the winter flu season is difficult, experts say
The findings are based on the analysis of samples collected in Europe during the 1918 pandemic.
The 1918 flu pandemic, commonly referred to as the Spanish flu, was a category 5 influenza pandemic caused by an unusually severe and deadly Influenza A virus strain of subtype H1N1. The difference between the influenza mortality age-distributions of the 1918 epidemic and normal epidemics.
These pandemics, in contrast to seasonal influenza, are caused by antigenic shifts involving animal influenza viruses. To date, all known flu pandemics have been caused by influenza A viruses, and they follow the same pattern of spreading from an origin point to the rest of the world over the course of multiple waves in a year.
The serotypes that have been confirmed in humans, ordered by the number of confirmed human deaths, are: H1N1 caused "Spanish flu" in 1918 and "Swine flu" in 2009. [36] H2N2 caused "Asian Flu". H3N2 caused "Hong Kong Flu". H5N1, "avian" or "bird flu". [37] H7N7 has unusual zoonotic potential. [38] H1N2 infects pigs and humans. [39] H9N2, H7N2 ...
