In a double-blind study of influenza in a population of college students in 1984, ribavirin small-particle aerosol treatment of 38 patients (18 treated, 20 control) infected with a new antigenic variant, influenza virus strain A/Victoria/7/83 (H1N1), was associated with statistically significant reductions in the height and duration of fever, systemic symptoms, and virus shedding. Patients received a total of 2.4 g of ribavirin over 42 h during 68 h of hospitalization without any side effects. In addition, in a study of patients infected with influenza virus strain B/Texas/1/84 (seven treated, eight control) treated with ribavirin aerosol showed a trend of more rapid recovery than control patients.

Unlabelled: Respiratory and encephalitic virus infections represent a significant risk to public health globally. Detailed investigations of immunological responses and disease outcomes during sequential virus infections are rare. Here, we define the impact of influenza virus infection on a subsequent virus encephalitis.

Ecological Drivers of Evolution of Swine Influenza in the United States: A Review.

Influenza A viruses (IAVs) pose a major public health threat due to their wide host range and pandemic potential. Pigs have been proposed as "mixing vessels" for avian, swine, and human IAVs, significantly contributing to influenza ecology. In the United States, IAVs are enzootic in commercial swine farming operations, with numerous genetic and antigenic IAV variants having emerged in the past two decades.

3-Fluoroneuraminosyl fluorides are invaluable probes for studying the catalytic mechanism of sialidases (neuraminidases), and as sialidase inhibitors. Significantly, when a C-3 equatorial fluorine is installed on a C-4 functionalised N-acylneuraminic acid (Neu)-based template, the compounds are potent and selective inhibitors of both influenza and parainfluenza sialidases, and of virus replication. Typically, the reported syntheses of 3-fluoroneuraminosyl fluorides involve either an enzymatic or a chemical synthesis that have uncontrolled stereoselectivity in the introduction of fluorine at C-3 of Neu and consequently yield a mixture of C-3 ax and C-3 eq fluoro derivatives.

Background: Previous research has underscored the efficacy of individual control strategies in mitigating influenza spread within communal settings; however, the unique dynamics of residential summer camps-characterized by close contact and high social interaction-present distinct challenges for outbreak management.

Purpose: The purpose of this study was to evaluate and compare the effectiveness of two targeted antiviral prophylaxis protocols using oseltamivir in controlling influenza outbreaks within a residential youth camp, aiming to provide evidence-based insights for optimizing outbreak management in communal settings with high social interaction.

Design: This retrospective study analyzed the progression of influenza outbreaks in a residential youth camp using two antiviral prophylaxis protocols with oseltamivir.

The H9N2 subtype of avian influenza virus (AIV) is widely distributed among poultry and wild birds and is also a threat to humans. During AIV active surveillance in Liaoning province from 2015 to 2016, we identified ten H9N2 strains exhibiting different lethality to chick embryos. Two representative strains, A/chicken/China/LN07/2016 (CKLN/07) and A/chicken/China/LN17/2016 (CKLN/17), with similar genomic background but different chick embryo lethality, were chosen to evaluate the molecular basis for this difference.
