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.

• Response to mRNA COVID-19 vaccination in three XLA patients Sun, 07 Aug 2022 06:00:00 -0400
  X-linked agammaglobulinemia (XLA) is an inborn error of immunity characterized by insufficient production of immunoglobulins and lack of measurable antibody response to vaccines. The rise of novel infections limits the protective effect of immunoglobulin replacement in immunodeficient patients though. While XLA patients are not expected to mount an antibody response to COVID-19 vaccination, it has been demonstrated that XLA patients can mount a T-cell response to COVID-19 vaccines, similar to...

  CONCLUSION: Hand washing with soap and wearing face masks should be recommended to GMT pilgrims.
• Dive into machine learning algorithms for influenza virus host prediction with hemagglutinin sequences Sun, 07 Aug 2022 06:00:00 -0400
  Influenza viruses mutate rapidly and can pose a threat to public health, especially to those in vulnerable groups. Throughout history, influenza A viruses have caused pandemics between different species. It is important to identify the origin of a virus in order to prevent the spread of an outbreak. Recently, there has been increasing interest in using machine learning algorithms to provide fast and accurate predictions for viral sequences. In this study, real testing data sets and a variety of...

  CONCLUSION: BM in South Africa has a high case-fatality and adverse sequelae occur frequently amongst survivors. Those with comorbidities (including HIV) are at highest risk.
• The role of human bocavirus as an agent of community-acquired pneumonia in children under 5 years of age in Fortaleza, Ceará (Northeast Brazil) Sat, 06 Aug 2022 06:00:00 -0400
  The human bocavirus (HBoV) is an agent of upper and lower respiratory infections, affecting mainly children under 5 years of age. Community-acquired pneumonia (CAP) is an important public health problem in developing countries, representing one of the main causes of hospitalizations and deaths in children. The aim of this study was to describe the prevalence of HBoV and the clinical and epidemiological characteristics in children diagnosed with CAP. For this purpose, nasopharyngeal aspirates...

  CONCLUSION: Co-administration of inactivated COVID-19 vaccine and seasonal influenza vaccine, especially the administration regimen that the seasonal influenza vaccine co-administered with the first dose of the inactivated COVID-19 vaccine, would be feasible.
• Functional characterization of bat IRF1 in IFN induction Sat, 06 Aug 2022 06:00:00 -0400
  Bats are natural hosts for various zoonotic viral diseases. However, they rarely show signs of disease infection with such viruses. During viral infection, members of the IRFs family induce the production of IFNβ and exert antiviral effects. However, the functions of bat IRFs remain unclear. In this study, the Tadarida brasiliensis IRF1 (TbIRF1) gene was first cloned and a series of bioinformatics studies were conducted. Results showed that bat IRF1 protein sequence showed a low similarity with...

• Associations between maternal reports of periconceptional fever from miscellaneous causes and structural birth defects Sat, 06 Aug 2022 06:00:00 -0400
  CONCLUSION: Our data suggests fever itself or other physiologic changes associated with many infections are associated with some birth defects. Women who are pregnant or planning to become pregnant may want to consider speaking with their healthcare provider about the best ways to avoid infections that may cause fever and for guidance on how to treat fevers during pregnancy.
