A viable virus aerosol sampler (VIVAS) effectively collected viable influenza A and B viruses from air inside a student health care center during an influenza outbreak. The viruses had "drifted" genes, showcasing the usefulness of the VIVAS for air sampling and noninvasive surveillance of viruses in circulation.

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.

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.

Background: Infections by and influenza viruses are vaccine-preventable diseases causing great morbidity and mortality. We evaluated pneumococcal and influenza vaccination practices during pre-international travel health consultations.

Methods: We evaluated data on pretravel visits over a 10-year period (1 July 2012 through 31 June 2022) from 31 sites in Global TravEpiNet (GTEN), a consortium of US healthcare facilities providing pretravel health consultations.

Influenza surveillance is important for monitoring influenza virus circulation and disease burden to inform influenza prevention and control measures. The aim of this study was to describe the epidemiology and to estimate the incidence of influenza in two communities in West Java, Indonesia, before and after the 2009 H1N1 pandemic. A population-based surveillance study in the community health care setting was conducted to estimate the annual incidence of influenza.

Future pandemic threats may be caused by novel coronaviruses and influenza A viruses. Here we show that when directly added to a cell culture, 12mer guanine RNA (G12) and its phosphorothioate-linked derivatives (G12(S)), rapidly entered cytoplasm and suppressed the propagation of human coronaviruses and influenza A viruses to between 1/100 and nearly 1/1000 of normal virus infectivity without cellular toxicity and induction of innate immunity. Moreover, G12(S) alleviated the weight loss caused by coronavirus infection in mice.
