We also performed functional analysis of the promoter structure at the end of the genome of the viruses belonging to the order Bunyavirales and revealed unique features of RNA synthesis that differ from other segmented RNA viruses in the family Nairoviridae.

In Japan, the proactive recommendations for HPV vaccinations were suspended in June 2013 due to public concerns about neuropsychological \"diverse symptoms\" following HPV vaccinations. The suspension resulted in the vaccination rate less than 1% among the eligible population. In April 2022, the Japanese government resumed the proactive HPV vaccination recommendations after 9 years of the suspension. Many Japanese people, however, still have concerns about the \"diverse symptoms\" as adverse reactions following HPV vaccinations. In this article, we critically evaluated the manuscripts cited in the HPV vaccine lawsuits in Japan, including computational and animal studies, which have been used as the theoretical basis for how HPV vaccinations could induce the \"diverse symptoms.\" We concluded that all the manuscripts had scientific flaws, which should not be used to prove that HPV vaccinations could induce the adverse reactions.

In Japan, the disease was successfully eradicated in 1957 as a result of exhaustive control measures including vaccination of dogs in accordance with the Rabies Prevention Law. Since then, Japan has continued to take rabies control measures based on this law, which are stricter than international standards. On the other hand, there have been a total of four imported human rabies cases found in Japan. The fourth imported case confirmed in Toyohashi City in May 2020 is still fresh in our minds. In April 2022, special measures were taken to quarantine dogs brought by evacuees from Ukraine to Japan, and many people expressed concern about the introduction of rabies into Japan.

Sporadic cases of human infection, likely resulting from close contact with infected animals, have been reported. In March 2024, clinical signs (e.g., reduced feed intake, altered milk quality, and decreased milk production) were observed in dairy cattle on a farm in Texas, USA, where H5N1 HPAIV was subsequently isolated. By December 2024, infections had been reported in dairy cattle across 15 states in the USA. Cases of infection have also been documented in cats near affected farms and in humans suspected of exposure through contact with infected cattle or chickens that acquired the virus from cattle. These developments have raised concerns about the potential for further transmission of H5N1 HPAIV to humans. In recent studies, H5N1 HPAIV strains isolated from cattle and humans exhibited high pathogenicity in mice and ferrets. Furthermore, ferret studies showed efficient transmission via respiratory droplets. This unprecedented spread of H5N1 HPAIV among mammals raises concerns about the emergence of a virus capable of efficient human-to-human transmission via respiratory droplets. Continued global surveillance of infection dynamics is essential to mitigate this potential public health threat.</p>","PeriodicalId":75275,"journal":{"name":"Uirusu","volume":"74 2","pages":"117-130"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
