Article Synopsis
- - Japan's approach to COVID-19 has focused on a cluster-based strategy, considering the varying levels of virus transmission (overdispersion) throughout the pandemic.
- - Research aimed to investigate how transmission heterogeneity shifted with new variants like Alpha, Delta, and Omicron in Yamagata Prefecture, using detailed contact tracing data.
- - Findings indicated that even with the emergence of new variants, transmission variability persisted, emphasizing the need for ongoing monitoring and a sustainable system for analyzing epidemic data.
Public health interventions have played an important role in controlling coronavirus disease 2019 (COVID-19), which is a rapidly spreading infectious disease. To contribute to future COVID-19 countermeasures, we aimed to verify the results of the countermeasures employed by public health centers (PHCs) against the first wave of COVID-19 in Yamagata Prefecture, Japan (Yamagata). Between January and May 2020, 1,253 patients suspected of SARS-CoV-2 infection were invited for testing.

Although Streptococcus suis has attracted public attention as a major swine and human pathogen, this bacterium has also been isolated from other animals, including ruminants. However, recent taxonomic studies revealed the existence of other species that were previously identified as S. suis, and some of these isolates were reclassified as the novel species Streptococcus ruminantium.

The incidence of modified measles (M-Me), characterized by milder symptoms than those of typical measles (T-Me), has been increasing in Japan. However, the outbreak dominated by M-Me cases has not been thoroughly investigated worldwide. The largest importation-related outbreak of measles with genotype D8 occurred in Yamagata Prefecture, Japan, from March to April 2017.
