Clinically Relevant Risk of Hepatitis B Virus Infection and Reactivation in People with HIV After Withdrawal of Anti-HBV–Active Antiretroviral Therapy in Japan

Eisuke Adachi, Aiko Okazaki, Yoshiaki Kanno +2 more

Open Forum Infectious Diseases

Type
Cohort study
Scope
Japan

Why it matters nowThe data underscore potential vulnerabilities in viral containment when standard prophylactic medication elements are removed from ongoing care plans. These observations may assist health authorities in refining monitoring protocols for patient populations transitioning between therapeutic strategies in areas where population-level immunization coverage remains incomplete.

Effectiveness of inactivated and live-attenuated influenza vaccines in children during the 2025–2026 influenza season with genetically distinct influenza A and B viruses

Lack of respiratory droplet transmission of two recent human influenza A(H5N1) viruses in female ferrets

Tong Wang, Chunyang Gu, Lizheng Guan +7 more

International Journal of Infectious Diseases

Type
Journal article
Scope
Japan, United States

Why it matters nowThe findings support continued evaluation of emerging H5N1 viruses because transmission characteristics may vary among viruses in this clade. The abstract links this work to risk assessment of pandemic potential but does not provide clinical guidance or population-level estimates.

Genomic epidemiology and evolutionary dynamics of Bordetella pertussis: A comparative study between China and Global Strains (2018–2024)

Jianguang Cai, Yanwei Zhang, Shuang Wu +13 more

International Journal of Infectious Diseases

Type
Genomic study
Scope
China, Japan, United States

Why it matters nowThe convergence of resistance, hypervirulence, and potential vaccine escape within a dominant lineage is framed by the authors as grounds to revisit antibiotic stewardship and pertussis vaccination strategies.

Phylogeny and molecular evolution of the first local monkeypox virus cluster in Guangdong Province, China

Jianhai Yu, Xin Zhang, Jiajun Liu +15 more

Nature Communications

Type
Genomic study
Scope
China, Japan, Portugal

Why it matters nowThe findings are positioned by the authors as contributing to understanding of the ongoing mpox outbreak in China and to informing joint prevention and control strategies.

Effectiveness of 23-Valent Pneumococcal Polysaccharide Vaccine against Invasive Pneumococcal Disease in Adults, Japan, 2013–2017

Reiko Shimbashi, Motoi Suzuki, Bin Chang +14 more

Emerging Infectious Diseases

Type
Journal article
Scope
Japan

Why it matters nowThe findings address whether pediatric pneumococcal conjugate vaccination alters adult protection from PPSV23 against invasive pneumococcal disease and may inform interpretation of adult pneumococcal vaccine performance in Japan.

Estimating the asymptomatic proportion of coronavirus disease 2019 (COVID-19) cases on board the Diamond Princess cruise ship, Yokohama, Japan, 2020

Kenji Mizumoto, Katsushi Kagaya, Alexander Zarebski +1 more

Eurosurveillance

Type
Journal article
Scope
Japan

Why it matters nowThe findings provide early empirical evidence on asymptomatic COVID-19 transmission in a closed setting, relevant to outbreak investigation and transmission dynamics during the early pandemic phase.

Revisiting the taxonomy and evolution of pathogenicity of the genus Leptospira through the prism of genomics

Antony T. Vincent, Olivier Schiettekatte, Cyrille Goarant +12 more

PLOS Neglected Tropical Diseases

Type
Genomic study
Scope
Algeria, France, Japan

Why it matters nowThe findings expand understanding of Leptospira diversity in environmental reservoirs relevant to zoonotic transmission. The identification of new potentially infectious species and insights into virulence evolution may inform future surveillance and risk assessment, though clinical significance remains to be determined.

Type
Commentary
Scope
China, Japan

Why it matters nowThe article identifies a possible need for public health authorities and surveillance systems to remain prepared for increased norovirus activity associated with the GII.P17-GII.17 strain. The abstract does not establish the magnitude or duration of any future increase.

Regulatory Systems for Prevention and Control of Rabies, Japan

Hiromi Takahashi-Omoe, Katsuhiko Omoe, Nobuhiko Okabe

Emerging Infectious Diseases

Type
Journal article
Scope
Japan

Why it matters nowThe paper presents Japan’s rabies regulatory system as a practical example of elimination-oriented prevention and control. The abstract explicitly frames the current system as a potential model for rabies elimination elsewhere.
