  • Future studies should investigate the molecular epidemiology of these diseases in waterfowl populations. Future studies should examine the risk factors associated with the presence and distribution of these diseases. Future studies should develop and implement effective disease control and prevention strategies in waterfowl populations.

  • Further studies are needed to investigate the pathogenesis of FDMV. The development of diagnostic tests and vaccines for FDMV is a potential area of future research.

    Genome sequence of Fraser’s dolphin morbillivirus isolated from a stranded Fraser’s dolphin (Lagenodelphis hosei) in Hawaiʻi · 2026 · DOI

  • There is a lack of knowledge about the genome sequence of Fraser’s dolphin morbillivirus. The identification of FDMV as a distinct member of the genus Morbillivirus addresses this gap.

    Genome sequence of Fraser’s dolphin morbillivirus isolated from a stranded Fraser’s dolphin (Lagenodelphis hosei) in Hawaiʻi · 2026 · DOI

  • The dynamics of Nipah virus in India are not well understood. The roles of ecological factors and health systems in determining the outcome of Nipah virus outbreaks are not well studied.

    Two geographies, one virus: What recurrent Nipah spillover in India reveals · 2026 · DOI

  • Vaccination coverage has dropped in recent years due to pandemic-related disruptions and health system challenges. Many affected children are either too young to be vaccinated or have missed their doses.

    Resurgence of measles in Bangladesh amid a global upsurge: an urgent call for emergency public health response · 2026 · DOI

  • The neutralizing activity present in human serum is considered a correlate of protection against SARS-CoV-2 infection and disease but the mechanisms by which serum antibodies are transported into the lumen of the respiratory tract, where they are required to interact with virus particles and infected cells remain incompletely understood.

    Antibody Transcytosis and Neutralizing Activity in Respiratory Epithelial Cells · 2026 · DOI

  • The study identifies a gap in the existing literature on herd immunity to measles, mumps, and rubella in Russian regions. There is a need to assess the level of population immunity to these diseases in different regions.

    Herd immunity to measles, rubella, and mumps in several Russian regions · 2026 · DOI

  • The study identifies a gap in the understanding of the burden of measles in northwestern Nigeria. The study highlights the need for improved vaccination coverage and public health strategies to control measles outbreaks.

    Measles and rubella seropositivity among suspected measles cases in northwestern region of Nigeria · 2026 · DOI

  • Within the genus Bandavirus, the non-structural protein NSs functions as the primary antagonist of innate immune responses, although mechanistic details for BHAV remain unknown.

    Functional divergence of the NSs protein defines interferon antagonism and viral fitness across Bhanja virus lineages. · 2026 · DOI

  • The study is limited to data from the National Notifiable Disease Surveillance System. The study does not provide a comprehensive review of prior work on measles epidemiology in Australia.

    Measles epidemiology in Australia: 2014 to 2024 · 2026 · DOI

  • The study had a limited sample size, with 87 samples selected for whole-genome sequencing. The molecular resolution was too low to confirm all separate epidemiologically linked transmission chains. Some regions of the genome had low coverage, with < 50 reads.
