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
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.

- Epidemiology of invasive nontypeable Haemophilus influenzae disease-United States, 2008-2019 Wed, 01 Feb 2023 06:00:00 -0500
CONCLUSION: NTHi causes substantial invasive disease, especially among older adults, pregnant/postpartum women, and neonates. Enhanced surveillance and evaluation of targeted interventions to prevent perinatal NTHi infections may be warranted.
- Postinfluenza Cardiac Tamponade: A Review of Published Case Reports Wed, 01 Feb 2023 06:00:00 -0500
Increased vaccination rates and better understanding of influenza virus infection and clinical presentation have improved the disease's overall prognosis. However, influenza can cause life-threatening complications such as cardiac tamponade, which has only been documented in case reports. We searched PubMed/Medline and SCOPUS and EMBASE through December 2021 and identified 25 case reports on echocardiographically confirmed cardiac tamponade in our review of influenza-associated cardiac...
- Risk Factors for Respiratory Viral Infections: A Spotlight on Climate Change and Air Pollution Wed, 01 Feb 2023 06:00:00 -0500
Climate change has both direct and indirect effects on human health, and some populations are more vulnerable to these effects than others. Viral respiratory infections are most common illnesses in humans, with estimated 17 billion incident infections globally in 2019. Anthropogenic drivers of climate change, chiefly the emission of greenhouse gases and toxic pollutants from burning of fossil fuels, and the consequential changes in temperature, precipitation, and frequency of extreme weather...
- Assessment of influenza A (H1N1, H3N2) oseltamivir resistance during 2017-2019 in Iran Wed, 01 Feb 2023 06:00:00 -0500
CONCLUSION: Evaluation of NA gene sequences, showed no resistant viruses to oseltamivir. Given that the viruses in the present study were the last viruses circulating in Iran before COVID-19 pandemic, the results will be beneficial to have a worthy comparison with the strains circulating after the pandemic. Constant monitoring for the emergence of drug-resistant variants and antigenic changes are crucial for all countries.

BACKGROUND: The recent outbreaks of Marburg virus disease (MVD) in Guinea and Ghana have become a major public health concern not only to the West African sub-region but a threat to global health.

CONCLUSION: Children, female sex, inpatient, hospital bed capacity, and private hospitals were negatively associated with baloxavir prescription.
- BRD4 is involved in viral exacerbation of chronic obstructive pulmonary disease Wed, 01 Feb 2023 06:00:00 -0500
CONCLUSIONS: Our findings indicate that CS and viruses may synergistically induce IL-6 and IL-8 expression through their synergistic induction of BRD4 expression, which might contribute to the enhanced inflammatory response in the viral exacerbation of COPD.
- Trends in respiratory diseases before and after the COVID-19 pandemic in China from 2010 to 2021 Wed, 01 Feb 2023 06:00:00 -0500
CONCLUSION: Our study demonstrated the incidence of the seven respiratory diseases decreased rapidly during the COVID-19 pandemic in 2020 and 2021. At the end of 2021, we did see a rising trend for the seven respiratory diseases compared to the year 2020 when the NPIs relaxed in China, but the rising trend was not significant after adjusting for the NPIs indicators. Our study showed that NPIs have an effect on respiratory diseases, but Relaxation of NPIs might lead to the resurgence of...
- Vinyl Sulfone-functionalized Acetalated Dextran Microparticles as a Subunit Broadly Acting Influenza Vaccine Tue, 31 Jan 2023 06:00:00 -0500
Influenza is a global health concern with millions of infections occurring yearly. Seasonal flu vaccines are one way to combat this virus; however, they are poorly protective against influenza as the virus is constantly mutating, particularly at the immunodominant hemagglutinin (HA) head group. A more broadly acting approach involves Computationally Optimized Broadly Reactive Antigen (COBRA). COBRA HA generates a broad immune response that is capable of protecting against mutating strains....
- Clonal Kinetics and Single-Cell Transcriptional Profiles of T Cells Mobilized to Blood by Acute Exercise Tue, 31 Jan 2023 06:00:00 -0500
CONCLUSIONS: Acute exercise promotes an oligoclonal T-cell repertoire by preferentially mobilizing the most dominant clones, several of which are specific to known viral antigens and display differentially expressed genes indicative of cytotoxicity, activation, and apoptosis.
