    Abstract In Japan, based on the National Epidemiological Surveillance of Infectious Diseases (NESID) Program, influenza cases from ~5,000 sentinel sites are monitored weekly as part of influenza surveillance (as number of influenza cases/sentinel site). One limitation is that the number of influenza tests conducted is not reported. Separately, the National Hospital Organization (NHO), with ~140 hospitals, routinely publishes three indicators: number of influenza tests, influenza-positive case counts, and test positivity. We used NESID and NHO data from April 2011 to June 2022 to assess the usefulness of multiple indicators to monitor influenza activity. Temporal trends of the NHO and NESID indicators were similar, and NHO indicator levels well-correlated with those of the NESID indicator. Influenza positivity in the NHO data, however, showed an earlier rise and peak time compared to the NESID indicator. Importantly, through the non-epidemic summer periods and the coronavirus disease 2019 pandemic, a sizable number of influenza tests continued to be done at NHO hospitals, with results showing considerably low case counts and test positivity. These data show that a relatively small number of sentinel sites is sufficient to monitor influenza activity nationally, and, that utilizing multiple indicators can increase our confidence in situational awareness and data interpretations.

    Abstract Since the first case of COVID-19 was reported in Wuhan, China, in December 2019, the SARS-CoV-2 epidemic has spread all over the world and has become a significant public health issue. The development of treatments for COVID-19 is currently in progress; however, their effects remain limited, and the development of more effective therapeutics is desired. Thus, sufficient understanding of the pathophysiology of COVID-19 is essential to develop effective therapeutics for this disease. Pathological analyses in particular play an important role to demonstrate the causal link between an infectious disease and the pathogen and elucidate the mechanism of pathogenesis. As per pathological analyses to date, respiratory organs are identified as the major affected organs in most COVID-19 cases; also, various lesions were noted in other organs. Further, there have been increasing reports that show that the immune responses of the host contribute to the deterioration of the pathological condition of COVID-19, and a novel concept of MIS-C/MIS-A is also being established. Thus, in this article, we have provided an overview of the pathology of COVID-19 from a histopathological and immunological perspective focusing on the mechanisms of COVID-19 pathogenesis.

    Abstract Persons in Japan who did not intend to receive COVID-19 vaccines after widespread rollout were less likely than others to engage in preventive measures or to be afraid of getting infected or infecting others. They were also not less likely to engage in potentially high-risk behaviors, suggesting similar or higher exposure risks.

    Abstract A nationwide survey of SARS-CoV-2 antinucleocapsid seroprevalence among blood donors in Japan revealed that, as of November 2022, infection-induced seroprevalence of the population was 28.6% (95% CI 27.6%-29.6%). Seroprevalence studies might complement routine surveillance and ongoing monitoring efforts to provide a more complete real-time picture of COVID-19 burden.

    Abstract Based on national surveillance data, we describe an unprecedented increase in syphilis case reports in Japan, with a surge in 2021-2022 reaching 10141 cases in Week 42, 2022, a 1.7-fold increase over the same period in 2021. This already represented the highest annual case count in nearly half a century; by Week 52, 2022, the number reached 12 966, far surpassing the 7978 cases in 2021. Predominantly affecting heterosexual men and young women, the proportionate increase in primary and secondary syphilis cases suggests a true increase in incidence. The syphilis surge during the pandemic poses a serious public health concern and underscores the importance of adequate testing and preventive measures.
