An alternative to vaccination used in the 1918 flu pandemic was the direct transfusion of blood, plasma, or serum from recovered patients. Though medical experiments of the era lacked some procedural refinements, eight publications from 1918 to 1925 reported that the treatment could approximately halve the mortality in hospitalized severe cases ...
The following is a list of WHO recommended strains for the Northern Hemisphere influenza season. Starting in the 2012–2013 season, the recommendation shifted to include the composition of a quadrivalent influenza vaccine (QIV) that contains both influenza B lineages, alongside a trivalent influenza vaccine (TIV) containing one influenza B lineage.
The EMEA reported results from some clinical trials in the CHMP Assessment Report. These relate to vaccination against H5N1 (Bird Flu) and not H1N1 (Swine Flu). [21] H5N1-007 was initiated at a single site in Belgium (Ghent) in March 2006. H5N1-008 was initiated at 41 sites in seven countries (6 EU MS plus Russia) in May 2006.
These strains of swine flu rarely pass from human to human. Symptoms of zoonotic swine flu in humans are similar to those of influenza and influenza-like illness and include chills, fever, sore throat, muscle pains, severe headache, coughing, weakness, shortness of breath, and general discomfort.
Swine flu is usually caused by three subtypes - H1N1, H1N2 and H3N2. They occasionally infect humans, usually after direct or indirect exposure to pigs or contaminated environments.
Researchers investigated the pathogenic potential of swine H2N3 in Cynomolgus macaques, a surrogate model for human influenza infection. In contrast to human H2N2 virus, which served as a control and largely caused mild pneumonia similar to seasonal influenza A viruses, the swine H2N3 virus was more pathogenic causing severe pneumonia in ...
CHICAGO (Reuters) -H5N1 bird flu was confirmed in a pig on a backyard farm in Oregon, the first detection of the virus in swine in the country, the U.S. Department of Agriculture said on Wednesday.
From 2009 to 2014, oseltamivir resistance was very low in seasonal flu. In the 2010–11 flu season, 99.1% of H1N1, 99.8% of H3N, and 100% of Influenza B remained oseltamivir susceptible in the US. [56] In January 2012, the US and European CDCs reported all seasonal flu samples tested since October 2011 to be oseltamivir susceptible.
