BACKGROUND With growing accessibility and need over the past decades, the Internet has experienced a rapid increase in use globally. Specifically, with the accelerated development in information technology, more than 90% of Hong Kong’s citizens use the Internet, and 70% of children in the age group of 6-17 have daily access to it. However, despite the benefits of Internet technology, its addiction could pose serious social and health issues. Therefore, conducting research to investigate its causes and risk factors is fundamental. OBJECTIVE In this study, we examined the relationship between worry and Internet addiction among children in Hong Kong, and investigated the moderating effect of the permissive parenting style on such relationship. METHODS The participants consisted of 227 fourth-grade and fifth-grade students (120 males, 52.9%) from primary schools in Hong Kong with a mean age of 9.55 (SD = .58). Each participant was asked to complete the questionnaires, including the Internet Addiction Test for Internet addiction, the Penn State Worry Questionnaire for Children for worry, and the Parental Authority Questionnaire for the permissive parenting style. RESULTS The results indicated that worry was related to greater Internet addiction among children. Furthermore, there was a moderating effect of the permissive parenting style such that the positive association between worry and Internet addiction was stronger when the permissive parenting style was higher. CONCLUSIONS Our findings imply that parenting styles are influential in the prevention of Internet addiction.

Abstract Backgrounds Influenza virus can survive on some surfaces, facilitating indirect person-to-person transmission. Methods We collected swab samples weekly from commonly touched surfaces in 7 kindergartens and primary schools during the 2017/2018 winter influenza season in Hong Kong. Results We detected influenza virus ribonucleic acid (RNA) in 12 of 1352 samples (<1%) collected from 7 of 11 classrooms (5 to 2 × 106 RNA copies/mL). Viral RNA was more frequently recovered from communal items inside classrooms such as bookshelves and doorknobs. Conclusions Surface contamination indicates the potential role of fomites in influenza virus transmission in schools. Communal items inside classrooms may cause greater potential risks of transmission during influenza epidemics.
