Mettenleiter, Jürgen StechAbstractInfluenza A viruses (IAV) have caused seasonal epidemics and severe pandemics in humans. Novel pandemic strains as in 2009 may emerge from pigs, serving as perpetual virus reservoir. However, reliably effective vaccination has remained a key issue for humans and swine. Here, we generated a novel double-attenuated inf...

(CNN) — From climate change to superbugs, the World Health Organization has laid out 10 big threats to our global health in 2019. And unless these threats get addressed, millions of lives will be in jeopardy. Here’s a snapshot of 10 urgent health issues, according to the United Nations’ public health agency: Not vaccinating when you can One of the most controversial recent health topics in the US is now an international concern. “Vaccine hesitancy — the reluctance or refusal to vaccinate despite the availability of vaccines — threatens to reverse progress made in tackling vaccine-prevent...

In this study, we have constructed computational models for host tropism prediction on human-adapted subtypes of influenza HA proteins using random forest. The feature vectors of the prediction models were generated based on seven physicochemical properties of amino acids from influenza sequences of three major hosts. Feature aggregation and associative rules were further applied to select top 20 features and extract host-associated physicochemical signatures on the combined model of nonspecific subtypes. The prediction model achieved high performance ( Accuracy=0.948 , Precision=0.954 , MCC=0.922 ). Support and confidence...

We refer transmission of infections in India which have implications for Pakistan [1]. As compared to Pakistan, the range and burden of infectious diseases are enormous in India including Severe Acute Respiratory Syndrome (SARS) contagion in 2002 –2003, Influenza A virus epidemic of 2006 (avian influenza), 2007 Equine influenza, Swine flu pandemic outbreaks in 2009 and 2014 [2]. Moreover, episodes of infectious diseases continue to rise in India, with a recent surge of chikungunya and dengue cases in 2016 [1].

AbstractPurpose of ReviewZoonotic influenza viruses are those that cross the animal-human barrier and can cause disease in humans, manifesting from minor respiratory illnesses to multiorgan dysfunction. They have also been implicated in the causation of deadly pandemics in recent history. The increasing incidence of infections caused by these viruses worldwide has necessitated focused attention to improve both diagnostic as well as treatment modalities. In this first part of a two-part review, we describe the structure of zoonotic influenza viruses, the relationship between mutation and pandemic capacity, pathogenesis of i...

(NEW YORK) — This nasty flu season, which has been worsening for months, may finally be leveling off. Health officials on Friday said about 1 of every 13 visits to the doctor last week was for fever, cough and other symptoms of the flu. That’s no reason for health officials to celebrate yet: That level is among the highest in a decade. But it’s no worse than last week, and flu activity had been increasing each week since November. The Centers for Disease Control and Prevention report said the number of states reporting heavy flu patient traffic also held steady at 43. “I thought I was going to die,...

This study describes the phylogenetic characterization and replication kinetics of recently-isolated H3N8 virus from a nasal swab obtained from a sporadic case of natural infection in an unvaccinated horse from Montana, USA. The nasal swab tested positive for equine influenza by Real-Time Quantitative Reverse Transcription Polymerase Chain Reaction (RT-PCR). Further, the whole genome sequencing of the virus confirmed that it was the H3N8 subtype and was designated as A/equine/Montana/9564-1/2015 (H3N8). A BLASTn search revealed that the polymerase basic protein 1 (PB1), polymerase acidic (PA), hemagglutinin (HA), nucleopro...

Summary In 2009, a pandemic influenza A virus (pH1N1) spread globally in humans and infected a broad range of captive animals with close human contact. In February 2014, a pH1N1 virus was isolated from a sloth bear with respiratory signs at a US zoo, demonstrating that recurring epidemics present an ongoing threat to animals, including threatened species. This is the first report of pH1N1 infection in sloth bears. To understand the sloth bear virus within the global context of pH1N1, phylogenetic trees were inferred including full‐length sequences from available non‐human, non‐swine hosts, representing four families ...

Conclusion This study has identified a substance in the mucus secreted by a south Indian frog which can kill certain types of flu virus. Researchers often turn to natural substances with known health-giving properties to find potential new drugs for humans. For example, aspirin was developed based on a compound found in willow bark – which had been used in traditional medicine for hundreds of years. Some other drugs – such as some chemotherapy and anticlotting drugs – have also been developed from chemicals found in plants. By isolating the substances that have an effect the researchers can make sure...
