Influenza Virus Net is the web resource for anyone interested in influenza and flu pandemics. Influenza, commonly referred to as the flu, is an infectious disease caused by RNA viruses of the family Orthomyxoviridae (the influenza viruses), that affects humans, birds and other mammals. The virus spreads easily from person to person. Influenza circulates worldwide and can affect anybody in any age group. Influenza causes annual epidemics that peak during winter in temperate regions. Influenza is a serious public health problem that causes severe illnesses and deaths for higher risk populations. The most common symptoms of the disease are chills, fever, sore throat, muscle pains, severe headache, coughing, weakness/fatigue and general discomfort. Sore throat, fever and coughs are the most frequent symptoms. In more serious cases, influenza causes pneumonia, which can be fatal, particularly for the young and the elderly. An influenza epidemic can take an economic toll through lost workforce productivity, and strain health services. Vaccination is the most effective way to prevent infection.

The objectives of Influenza Virus Net are to be the public and professional information resource for influenza and to serve as a network in the exchange of information and news related to influenza.

  Avian Influenza -- Cambodia
  Abstract
  ---------
  In February 2021, routine sentinel surveillance for influenza-like illness in Cambodia detected a human avian influenza A(H9N2) virus infection. Investigations identified no recent H9N2 virus infections in 43 close contacts. One chicken sample from the infected child's house was positive for H9N2 virus and genetically similar to the human virus.

• Productivity costs associated with reactive school closures related to influenza or influenza-like illness in the United States from 2011 to 2019 Tue, 06 Jun 2023 06:00:00 -0400
  CONCLUSIONS: In recent years, we found significant heterogeneity in year-to-year costs of ILI-associated reactive school closures. These costs have been greatest in Tennessee and Kentucky and been elevated in rural or town areas relative to cities or suburbs. Our findings might provide evidence to support efforts to reduce the burden of seasonal influenza in these disproportionately impacted states or communities.
• Systems pharmacology approach to explore the mechanisms of Shufeng Jiedu Capsule on treating H1N1 infection Tue, 06 Jun 2023 06:00:00 -0400
  Background Influenza caused by H1N1 virus still affects human health. There is currently no effective strategy against H1N1 virus infection. The present study is to evaluate the mechanism of Shufeng Jiedu Capsule (SFJDC) in the treatment of H1N1 infection using an integrated systems pharmacology approach and experimental validation. SFJDC is recommended for the treatment of H1N1 infection in traditional Chinese medicine (TCM), whose mechanism of action is not precise. Methods: We systematically...

  CONCLUSION: An absence of seasonal predilection for the disease was noted with influenza A (H1N1) pdm09 being the predominant strain with influenza B seen as an emerging strain and an important contributor towards morbidity.

• The sliding motility of the bacilliform virions of Influenza A viruses Tue, 06 Jun 2023 06:00:00 -0400
  Influenza A virus (IAV) infection relies on the action of the hemagglutinin (HA) and neuraminidase (NA) membrane proteins. The HA ligands anchor the IAV virion to the cell's surface by binding the sialic acid (SA) present on the host's receptors while NA is an enzyme capable of cleaving the SA from the extracellular environment. It is believed that the activity of NA ligands increases the motility of the virions favoring the propagation of the infection. In this work, we develop a numerical...
• Resurgence of influenza and respiratory syncytial virus in Egypt following two years of decline during the COVID-19 pandemic: outpatient clinic survey of infants and children, October 2022 Mon, 05 Jun 2023 06:00:00 -0400
  CONCLUSIONS: A resurgence of influenza and RSV was detected in Egypt in the 2022-2023 winter season. Influenza caused a higher rate of infection than RSV, while RSV caused more severe symptoms than influenza. Monitoring a broader range of respiratory pathogens is recommended to estimate the ARI burden and risky groups for severe disease in Egypt.
• A multi-enzyme machine polymerizes the Haemophilus influenzae type b capsule Mon, 05 Jun 2023 06:00:00 -0400
  Bacterial capsules have critical roles in host-pathogen interactions. They provide a protective envelope against host recognition, leading to immune evasion and bacterial survival. Here we define the capsule biosynthesis pathway of Haemophilus influenzae serotype b (Hib), a Gram-negative bacterium that causes severe infections in infants and children. Reconstitution of this pathway enabled the fermentation-free production of Hib vaccine antigens starting from widely available precursors and...

  李某，男，2岁11个月，某年12月31日因“发热近1 d”就诊于某妇女儿童医院。辅助检查后诊断为发热、甲型流感病毒感染。当日14：00左右，医院为其开具口服药后嘱其回家观察，3~5 d后复查。患者返家途中突发抽搐，在附近医院就诊后又返回该妇女儿童医院抢救。当日22：00左右转至某儿童医院，经抢救无效死亡。李某家属认为该妇女儿童医院在诊疗过程中存在过错，遂诉至法院，申请医疗损害鉴定。.
• Herd immunity, vaccination and moral obligation Mon, 05 Jun 2023 06:00:00 -0400
  The public health benefits of herd immunity are often used as the justification for coercive vaccine policies. Yet, 'herd immunity' as a term has multiple referents, which can result in ambiguity, including regarding its role in ethical arguments. The term 'herd immunity' can refer to (1) the herd immunity threshold, at which models predict the decline of an epidemic; (2) the percentage of a population with immunity, whether it exceeds a given threshold or not; and/or (3) the indirect benefit...
• Mortality in Catalonia during the summer of 2022 and its relation with high temperatures and COVID-19 cases Mon, 05 Jun 2023 06:00:00 -0400
  CONCLUSION: Our study suggests that the main cause of the increase in deaths during summer 2022 in Catalonia was the high temperatures and its duration. The contribution of the COVID-19 seems to be limited.
