Article Synopsis
- * Recombinant variants, like the XBB strain, have emerged and become dominant, highlighting the need for ongoing surveillance of viral genome diversity.
- * A study in Norway revealed a recombination event in an immunocompromised patient, discovering a new viral strain formed from two existing lineages, emphasizing the need to monitor such events frequently.
Background: Non-pharmaceutical interventions implemented during the COVID-19 pandemic resulted in a marked reduction in influenza infections globally. The absence of influenza has raised concerns of waning immunity, and potentially more severe influenza seasons after the pandemic.
Methods: To evaluate immunity towards influenza post-COVID-19 pandemic we have assessed influenza A epidemics in Norway from October 2016 to June 2023 and measured antibodies against circulating strains of influenza A(H1N1)pdm09 and A(H3N2) in different age groups by hemagglutination inhibition (HAI) assays in a total of 3364 serum samples collected in 2019, 2021, 2022 and 2023.
Covid-19 and influenza vaccine effectiveness against associated hospital admission and death among individuals over 65 years in Norway: A population-based cohort study, 3 October 2022 to 20 June 2023.

Background: Co-circulation of SARS-CoV-2 and influenza virus can lead to double epidemics and increased pressure on health systems. To evaluate the effect of both vaccines, we estimated the adjusted vaccine effectiveness (aVE) of influenza and Covid-19 vaccines against related severe disease in the elderly population in Norway during the 2022/2023 season.
Methods: In this population-based cohort study, we included data from the Emergency preparedness register for Covid-19 (Beredt C19) on all individuals ≥ 65 years living in Norway between 3 October 2022 and 20 June 2023.
Background: During the COVID-19 pandemic, wastewater-based surveillance gained great international interest as an additional tool to monitor SARS-CoV-2. In autumn 2021, the Norwegian Institute of Public Health decided to pilot a national wastewater surveillance (WWS) system for SARS-CoV-2 and its variants between June 2022 and March 2023. We evaluated the system to assess if it met its objectives and its attribute-based performance.

- A new type of bird flu virus called H5N6 was discovered in Laos in 2014, and it can make chickens very sick.
- In a study, all 6 chickens infected with the virus got sick within 48 hours, showing high levels of the virus in their bodies.
- This virus is spreading in countries like Laos, China, and Vietnam, and has even caused some severe illnesses in humans, which could be a big problem for both birds and people.
The identification of immune pathways that protect against pathogens may lead to novel molecular therapies for both livestock and human health. Interferon (IFN) is a major response pathway that stimulates multiple genes targeted towards reducing virus. Viperin is one such interferon stimulated gene (ISG) that helps protect mammals from virus and may be critical to protecting chickens in the same way.
