Seropositivity for Influenza A(H1N1)pdm09 Virus among Frontline Health Care Personnel

Emerging Infectious Diseases, 2013
Seroprevalence of antibodies to influenza A(H1N1)pdm09 virus among 193 emergency department health care personnel was similar among 147 non-health care personnel (odds ratio 1.4, 95% CI 0.8-2.4). Working in an acute care setting did not substantially increase risk for virus infection above risk conferred by community-based exposures.

The Dual Role of Preexisting Immunity in Influenza: Protective Recall Versus Constraint of Novel Responses

Immunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT Preexisting immunity to influenza confers rapid protection against antigenically matched viruses but can also constrain responses to drifted variants. This review asks when and why prior infection or vaccination is protective versus detrimental, and which biological mechanisms—epitope masking by circulating antibody, inhibitory FcγRIIb ...

Swine Influenza in Sri Lanka

Emerging Infectious Diseases, 2013
To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004–2005 and 2009–2012, respectively.

A novel broad-spectrum treatment for respiratory virus infections : influenza-based defective interfering virus provides protection against pneumovirus infection in vivo [PDF]

, 2011
Respiratory viruses represent a major clinical burden. Few vaccines and antivirals are available, and the rapid appearance of resistant viruses is a cause for concern.

Results From the Third and Fourth WHO External Quality Assessments for the Molecular Detection of Respiratory Syncytial Virus

Influenza and Other Respiratory Viruses, Volume 20, Issue 8, August 2026.
ABSTRACT Background In 2016, the World Health Organization (WHO) initiated the global RSV surveillance programme, which aimed to strengthen laboratory diagnostic capacity and evaluate molecular detection test performance. External quality assessments (EQAs) are conducted regularly as part of this programme to ensure ongoing laboratory proficiency.

Differential contribution of PB1-F2 to the virulence of highly pathogenic H5N1 influenza A virus in mammalian and avian species [PDF]

, 2011
Highly pathogenic avian influenza A viruses (HPAIV) of the H5N1 subtype occasionally transmit from birds to humans and can cause severe systemic infections in both hosts.

The Spread of Influenza A(H1N1)pdm09 Virus in Madagascar Described by a Sentinel Surveillance Network

PLoS ONE, 2012
The influenza A(H1N1)pdm09 virus has been a challenge for public health surveillance systems in all countries. In Antananarivo, the first imported case was reported on August 12, 2009. This work describes the spread of A(H1N1)pdm09 in Madagascar.The diffusion of influenza A(H1N1)pdm09 in Madagascar was explored using notification data from a sentinel ...

Enhanced Human Antigen‐Specific B Cell Responses Using In Vitro 3D Tonsil Cultures Containing Stromal Cells

Advanced Healthcare Materials, Volume 15, Issue 22, 12 June 2026.
We developed a fully human 3D tonsil cell culture system incorporating supportive stromal cells that better sustains and activates immune cells than conventional methods. The model generates stronger, more targeted antibody responses to viral antigens and vaccines, providing a physiologically relevant and entirely human platform for studying immune ...
