A range of public health measures have been implemented to suppress local transmission coronavirus disease 2019 (COVID-19) in Hong Kong. We examined the effect these interventions and behavioural changes on incidence COVID-19, as well influenza virus infections, which might share some aspects dynamics with COVID-19.We analysed data laboratory-confirmed COVID-19 cases, surveillance outpatients all ages, hospitalisations children. estimated daily effective reproduction number (Rt) for H1N1...
The mental health consequences of the coronavirus disease (COVID-19) pandemic, community-wide interventions, and social media use during a pandemic are unclear. first most draconian interventions have been implemented in Wuhan, China, these countermeasures increasingly deployed by countries around world.The aim this study was to examine risk factors, including media, for probable anxiety depression community among professionals epicenter, China.We conducted an online survey via WeChat,...
Little is known about the community psychological and behavioral responses to influenza pandemics.Using random digit dialing, we sampled 12,965 Hong Kong residents in 13 cross-sectional telephone surveys between April November 2009, covering entire first wave of 2009 A(H1N1) pandemic. We examined trends anxiety, risk perception, knowledge on modes transmission, preventive behaviors.Respondents reported low anxiety levels throughout epidemic. Perceived susceptibility infection perceived...
Few studies have investigated associations between psychological and behavioral indices throughout a major epidemic. This study was aimed to compare the strength of different cognitive affective measures risk self-reported protective behaviors in series ten cross-sectional surveys conducted first wave influenza A/H1N1 pandemic.All were using questionnaire-based telephone interviews, with random digit dialing recruit adults from general population.

Background Effective risk communication about the outbreak of a newly emerging infectious disease in early stage is critical for managing public anxiety and promoting behavioral compliance. China has experienced unprecedented epidemic coronavirus (COVID-19) an era when social media fundamentally transformed information production consumption patterns. Objective This study examined engagement government responsiveness communications COVID-19 during based on analysis data from Sina Weibo,...
COVID-19 vaccine hesitancy can lead to reduced uptake and hinder the safe relaxation of other public health measures. This study aims explore factors associated with among adults before after implementation vaccination program in Hong Kong.
Background Vaccination was a core component for mitigating the 2009 influenza pandemic (pH1N1). However, vaccination program's efficacy largely depends on population compliance. We examined general decision-making pH1N1 using modified Theory of Planned Behaviour (TBP). Methodology conducted longitudinal study, collecting data before and after introduction vaccine in Hong Kong. Structural equation modeling (SEM) tested if TPB had explanatory utility uptake among adults. Principal Findings...
Background Whether information sources influence health protective behaviours during influenza pandemics or other emerging infectious disease epidemics is uncertain. Methodology Data from cross-sectional telephone interviews of 1,001 Hong Kong adults in June, 2009 were tested against theory and data-derived hypothesized associations between trust (formal/informal) information, understanding, self-efficacy, perceived susceptibility worry, hand hygiene social distancing using Structural...
ABSTRACT Background A range of public health measures have been implemented to delay and reduce local transmission COVID-19 in Hong Kong, there major changes behaviours the general public. We examined effect these interventions behavioral on incidence as well influenza virus infections which may share some aspects dynamics with COVID-19. Methods reviewed policy measured population through two telephone surveys, January 20-23 February 11-14. analysed data laboratory-confirmed cases,...
Hong Kong has implemented stringent public health and social measures (PHSMs) to curb each of the four COVID-19 epidemic waves since January 2020. The third wave between July September 2020 was brought under control within 2 m, while fourth starting from end October taken longer bring lasted at least 5 mo. Here, we report pandemic fatigue as one potential reasons for reduced impact PHSMs on transmission in wave. We contacted either 500 or 1,000 local residents through weekly random-digit...
