ABSTRACT
School closure was the only main control measure that Japan took into action from late February to late March in 2020. Accurate evaluation of how Japanese citizens responded to the impact of school closure remains a challenge. Data from the Google COVID-19 Community Mobility Report was used to analyze the mobility trend of Japanese citizens regarding six categories, including retail and recreation, grocery and pharmacy, parks, transit stations, workplace, and residential. The median percentage of mobility in all 47 prefectures of Japan was calculated during five periods of time, including one week before school closure, one week, two weeks, three weeks, and four weeks after school closure. There was a significant decline in the mobility trend of transit stations, grocery and pharmacy, parks, retail and recreation, and workplace at the moment after school closure compared to the prior period. Inversely, the mobility trend in staying at home remarkably increased following the implementation of school closure. Our study determined a significant change in the mobility trend of Japanese citizens before and after school closure. These data reflected the responsibility and the consciousness of Japanese citizens in mitigating COVID-19.

The analysis on 4 generations of this group, including 171 persons in 29 branches, 42 families showed that the disease was vertically inherited through generations like autosomal dominant inheritance. The incidence was 46.77% (26/62 patients). Male to female ratio was 2:1 (24 males:12 females). 5.55% of patients (2/36) have disease on at 15 years old or less, 52.78% (19/36) of patients onset between 16 to 40 years. 11.11% onset at 40 years or more. 30.56% of patients (11/36) were not identified the onset of disease.
