Hong Kong is an intermediate tuberculosis (TB) endemicity city dominated by reactivation diseases. A cross-sectional study on the clinical and epidemiologic data of newly diagnosed TB cases was conducted in such a setting, to examine association between ambient PM2.5 reactivation. After exclusion most likely resulting from recent infection, four distinct population phenotypes were delineated latent class analysis based their risk profiles (N = 2,153): 'Elderly male' (26%), 'Otherwise healthy...
Abstract Background As an emerging infectious disease with a heterogenous and uncertain transmission pattern, coronavirus 2019 (COVID-19) has created catastrophe in healthcare-associated infections (HAIs) posed significant challenge to infection control practices (ICPs) healthcare settings. While the unique characteristics of psychiatric patients clinical settings may make implementation ICPs difficult, evidence is lacking for compliance among workers (HCWs) setting during COVID-19 pandemic....
Increased risk of healthcare-associated infections (HAIs) in radiology departments has been reported recent years. Optimal infection control practices (ICPs) are the key to controlling HAIs, but few studies have investigated ICP compliance healthcare workers (HCWs) departments. To assess level HCWs a department. A participant observation supplemented with adenosine triphosphate (ATP) bioluminescence assay evaluation environmental cleanliness was conducted. More than 1000 hand hygiene (HH)...
Abstract This study aimed to provide reference for evaluating the achievability of hepatitis B virus (HBV) elimination in a high endemicity city with universal neonatal vaccination place over 30 years. Between September 2018 and October 2020, 2085 citizens from 1143 geographically random households Hong Kong completed questionnaire had blood-testing HBV markers (anti-HBs, HBsAg, anti-HBc, HBeAg). We evaluated epidemiology examined factors associated exposure, chronic diseases. The proportion...
Abstract Summer-spring predominance of tuberculosis (TB) has been widely reported. The relative contributions exogenous recent infection versus endogenous reactivation to such seasonality remains poorly understood. Monthly TB notifications data between 2005 and 2017 in Hong Kong involving 64,386 cases (41% aged ≥ 65; male-to-female ratio 1.74:1) were examined for the timing, amplitude, predictability variation seasonality. observed seasonal variabilities correlated with demographics clinical...
While the plausible role of ambient PM2.5 exposure in tuberculosis (TB) reactivation has been inferred from vitro experiments, epidemiologic evidence is lacking. We examined relationship between concentration and pulmonary TB (PTB) an intermediate endemicity city dominated by diseases. Spatio-temporal analyses were performed on notification data satellite-based annual mean Hong Kong. A total 52623 PTB cases 2005 to 2018 mapped over 400 sub-district units. standardised ratio population...
Hong Kong is an Asia-Pacific City with low incidence but periodic local outbreaks of dengue. A mixed-method assessment the risk expansion dengue endemicity in such setting was conducted. Archived blood samples healthy adult donors were tested for anti-dengue virus IgG at 2 time-points 2014 and 2018/2019. Data on monthly notified cases, meteorological vector (ovitrap index) variables collected. The (DENV) seroprevalence adults 2.2% (95%C.I. = 1.8-2.8%, n 3827) whereas that 2018/2019 1.7%...
