1 Σεπ 2020 · Retrospective epidemiological studies have now shown that a significant contribution to high mortality during the Spanish Flu pandemic came from pneumococcal co‐infections, amounting to as much as one fifth of influenza victims, with a 34% mortality.
1 Ιαν 2021 · We find that sunlight strongly protects against getting influenza. This relationship is driven almost entirely by the severe H1N1 epidemic in fall 2009. A 10% increase in relative sunlight decreases the influenza index in September or October by 1.1 points on a 10-point scale.
Influenza viruses, including the 1918 pandemic virus, usually cause acute self-limited respiratory infections in humans. Symptoms typically include fever, coryza (inflammation of the nasal mucosa), cough, headache, fatigue, and malaise, often persisting for 7 to 10 days, followed by complete recovery.
26 Οκτ 2021 · Within the influenza virus, there are four types: A, B, C, and D. Influenza D is found only in cows. Influenza viruses C and B are not ordinarily deadly to humans. Both influenza C and B are vastly older types of the virus, far more acclimated to humans.
26 Οκτ 2022 · A large difference in the UV sensitivity of different influenza viruses from the last approx. 100 years could not be detected. Thus, it is reasonable to assume that future influenza viruses will also be similarly UV-sensitive or that UV can also inactivate new influenza viruses.
19 Ιαν 2018 · But influenza viruses are moving targets, and a pandemic virus could nevertheless emerge with as little warning in 2018 as in 1918. As evidenced by this current flu season, influenza viruses can rapidly acquire mutations that evade our most recent vaccine formulations.
22 Ιουν 2018 · Whether the damage that results from severe influenza paves the way for bacteria normally carried in the nasopharynx to descend to the lung and trigger the neutrophil response, or whether the virus itself triggers this immunopathological pathway is not yet clear, but the implications for future plans and treatment strategies for pandemic ...
