SARS transmission among hospital workers in Hong Kong

Despite infection control measures, breakthrough transmission of severe acute respiratory syndrome (SARS) occurred for many hospital workers in Hong Kong. We conducted a case-control study of 72 hospital workers with SARS and 144 matched controls. Inconsistent use of goggles, gowns, gloves, and caps was associated with a higher risk for SARS infection (unadjusted odds ratio 2.42 to 20.54, p < 0.05). The likelihood of SARS infection was strongly associated with the amount of personal protection equipment perceived to be inadequate, having <2 hours of infection control training, and not understanding infection control procedures. No significant differences existed between the case and control groups in the proportion of workers who performed high-risk procedures, reported minor protection equipment problems, or had social contact with SARS-infected persons. Perceived inadequacy of personal protection equipment supply, infection control training <2 hours, and inconsistent use of personal protection equipment when in contact with SARS patients were significant independent risk factors for SARS infection.     

SARS transmission, risk factors, and prevention in Hong Kong

We analyzed information obtained from 1,192 patients with probable severe acute respiratory syndrome (SARS) reported in Hong Kong. Among them, 26.6% were hospital workers, 16.1% were members of the same household as SARS patients and had probable secondary infections, 14.3% were Amoy Gardens residents, 4.9% were inpatients, and 9.9% were contacts of SARS patients who were not family members. The remaining 347 case-patients (29.1%) had undefined sources of infection. Excluding those <16 years of age, 330 patients with cases from "undefined" sources were used in a 1:2 matched case-control study. Multivariate analysis of this case-control study showed that having visited mainland China, hospitals, or the Amoy Gardens were risk factors (odds ratio [OR] 1.95 to 7.63). In addition, frequent mask use in public venues, frequent hand washing, and disinfecting the living quarters were significant protective factors (OR 0.36 to 0.58). In Hong Kong, therefore, community-acquired infection did not make up most transmissions, and public health measures have contributed substantially to the control of the SARS epidemic.     

Probable secondary infections in households of SARS patients in Hong Kong

Although severe acute respiratory syndrome (SARS) is highly infectious in clinical settings, SARS has not been well examined in household settings. The household and household member attack rates were calculated for 1,214 SARS case-patients and their household members, stratified by two phases of the epidemic. A case-control analysis identified risk factors for secondary infection. Secondary infection occurred in 14.9% (22.1% versus 11% in earlier and later phases) of all households and 8% (11.7% versus 5.9% in the earlier and later phases) of all household members. Healthcare workers' households were less likely to be affected. Risk factors from the multivariate analysis included at-home duration before hospitalization, hospital visitation to the SARS patient (and mask use during the visit), and frequency of close contact. SARS transmission at the household level was not negligible in Hong Kong. Transmission rates may be greatly reduced with precautionary measures taken by household members of SARS patients.     

SARS-related perceptions in Hong Kong

To understand different aspects of community responses related to severe acute respiratory syndrome (SARS), 2 population-based, random telephone surveys were conducted in June 2003 and January 2004 in Hong Kong. More than 70% of respondents would avoid visiting hospitals or mainland China to avoid contracting SARS. Most respondents believed that SARS could be transmitted through droplets, fomites, sewage, and animals. More than 90% believed that public health measures were efficacious means of prevention; 40.4% believed that SARS would resurge in Hong Kong; and approximately equals 70% would then wear masks in public places. High percentages of respondents felt helpless, horrified, and apprehensive because of SARS. Approximately 16% showed signs of posttraumatic symptoms, and approximately equals 40% perceived increased stress in family or work settings. The general public in Hong Kong has been very vigilant about SARS but needs to be more psychologically prepared to face a resurgence of the epidemic.     

Stigma and sex work from the perspective of female sex workers in Hong Kong

While the stigma surrounding sex work is both well documented and easily recognised, few studies examine stigma in this context from the perspective of the sex workers themselves. In this article we report on a study using a modified grounded theory approach to analyse a series of semi-structured interviews with 49 female sex workers in Hong Kong, in order to examine the ways in which this group experiences and negotiates the stigma which arises from their employment in the sex industry. Sex workers in Hong Kong were subject to various stigmatising forces in their daily lives in their interactions with the public, the police and their families. These processes could have a negative impact on the sex workers' health, both through obvious manifestations such as physical or verbal abuse and through more subtle processes such as those which generated or perpetuated vulnerability and those which compelled the sex workers to conceal their identities and withdraw themselves from social networks. These findings are situated in the context of broader research surrounding sex work, drawing attention to the consequences of stigma on health and their interaction with health-service providers, before briefly discussing possible means of overcoming stigma-related barriers to providing adequate healthcare for this marginalised group.

Cluster of SARS among medical students exposed to single patient, Hong Kong

We studied transmission patterns of severe acute respiratory syndrome (SARS) among medical students exposed exclusively to the first SARS patient in the Prince of Wales Hospital in Hong Kong, before his illness was recognized. We conducted a retrospective cohort study of 66 medical students who visited the index patient's ward, including 16 students with SARS and 50 healthy students. The risk of contracting SARS was sevenfold greater among students who definitely visited the index case's cubicle than in those who did not (10/27 [41%] versus 1/20 [5%], relative risk 7.4; 95% confidence interval 1.0 to 53.3). Illness rates increased directly with proximity of exposure to the index case. However, four of eight students who were in the same cubicle, but were not within 1 m of the index case-patient, contracted SARS. Proximity to the index case-patient was associated with transmission, which is consistent with droplet spread. Transmission through fomites or small aerosols cannot be ruled out.

Prevalence of hospital infection and antibiotic use at a university medical center in Hong Kong

Hospital infection prevalence surveys were performed in our 1400-bed University medical centre in Hong Kong from 1985 to 1988. We investigated the rates of four major hospital-acquired infections (HAIs) (pneumonia, symptomatic urinary tract infection, surgical site infection and laboratory-confirmed bloodstream infection) in order to identify current distribution and any changes after 15 years. A one-day point prevalence study was performed on 7 September 2005. All inpatients were surveyed for HAIs, community-acquired infections (CAIs), risk factors, pathogenic isolates and antibiotics prescribed. Infections were diagnosed according to Centers for Disease Control and Prevention (CDC) criteria. In total, 1021 patients were surveyed; of these, 41 had 42 HAIs (4% prevalence) and 389 (38%) were receiving antibiotics. The commonest HAI was pneumonia (1.4%) followed by bloodstream infection (0.9%) and symptomatic urinary tract infection (0.8%). The prevalence of postoperative surgical site infection was 5.6%. The nosocomial prevalence rate was highest in the Intensive Care Unit, followed by the Pediatric and Neonatal Intensive Care Units, Children's Cancer Centre/Bone Marrow Transplant Unit and Orthopaedics with Traumatology. Meticillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa were the commonest pathogens. The rates are significantly lower than previously and reflect the increased resources for infection control made available following the outbreak of severe acute respiratory syndrome (SARS).     

SARS-CoV antibody prevalence in all Hong Kong patient contacts

A total of 1,068 asymptomatic close contacts of patients with severe acute respiratory (SARS) from the 2003 epidemic in Hong Kong were serologically tested, and 2 (0.19%) were positive for SARS coronavirus immunoglobulin G antibody. SARS rarely manifests as a subclinical infection, and at present, wild animal species are the only important natural reservoirs of the virus.     

SARS-related virus predating SARS outbreak, Hong Kong

Using immunofluorescence and neutralization assays, we detected antibodies to human severe acute respiratory syndrome-associated coronavirus (SARS-CoV) and/or animal SARS-CoV-like virus in 17 (1.8%) of 938 adults recruited in 2001. This finding suggests that a small proportion of healthy persons in Hong Kong had been exposed to SARS-related viruses at least 2 years before the recent SARS outbreak.     

Some views about the training of the early childhood workforce in Hong Kong

This paper reports on a section of a larger project funded by the Hong Kong Council of Early Childhood Education and Services (CECES) which investigated early childhood education and training in Hong Kong. What is presented in this paper is the results of a survey of 1259 kindergarten and child care workers who responded to a survey questionnaire. Given current community concern about the inadequacy of training for the early childhood work force respondents were asked to reply to questions about what the minimum length of training should be, should the length of training be the same for kindergarten and child care, should training be unified, what content should be included in the training curriculum, what should the next level of training be after the basic course, were respondents interested in completing further training, should credit be given for previous training, identification of overlap in training courses, overall satisfaction with training received, identification of problems with current training and perceived solutions, overall satisfaction with career opportunities. The paper presents these results and discusses the implications of the findings for the early childhood workforce in Hong Kong.

The effect of centralized hospital administration on financial control and hospital service delivery: the case of Hong Kong.

Administration, financial control and service delivery are three mutually influential dimensions of a hospital system. The centralized hospital system of Hong Kong is a case-in-point that illustrates such influence. By spending only a small fraction of the Gross Domestic Product each year, the government has been able to provide limited modern health care services at nominal financial cost to the public. At the same time, hospitals are subject to a strict system of administrative and financial controls. Consequently, Hong Kong hospitals must utilize their limited facilities effectively to provide modern health services to the public. However, the trade-off between low-cost health services and limited facilities is the incurrence, by the public, of non-monetary costs in obtaining hospital admission.     

Occupational risk of Mycobacterium tuberculosis infection in hospital workers

We conducted a 4-year (1/89–12/92) retrospective cohort study among employees at a large metropolitan hospital where a nosocomial outbreak of multidrug-resistant tuberculosis (TB) had occurred. We compared the risk of tuberculin skin test (TST) conversion among employees who worked on wards where patients with culture-confirmed TB were cared for (“exposed”) with the risk among employees who worked on wards with no such patients (“unexposed”). Exposed employees had a higher 4-year risk of TST conversion (14.5%) than unexposed employees (1.4%) (adjusted relative risk 13.4; 95 percent confidence interval 5.1–35.2). Exposed employees had significantly higher risks of conversion than unexposed employees during 1989–91, but not for 1992. Among the exposed, ward clerks had a risk of conversion (15.6%) only slightly lower than nurses (18.2%). We conclude that employees who worked in areas where patients with active M. tuberculosis infection were cared for, including workers who did not provide direct patient care, had a higher risk of TST conversion than employees who did not work in these areas. Reasons for the decline in risk over time include outbreak termination, fewer admissions of patients with TB, implementation of effective infection control measures, and possible resistance to infection in some members of the study population.

Respiratory infections during SARS outbreak, Hong Kong, 2003

The effect of community hygienic measures during the outbreak of severe acute respiratory syndrome in Hong Kong was studied by comparing the proportion of positive specimens of various respiratory viruses in 2003 with those from 1998 to 2002. Community hygienic measures significantly reduced the incidence of various respiratory viral infections.     

Coming Out Experiences and Psychological Distress of Chinese Homosexual Men in Hong Kong

This study adopted a cognitive-behavioral conceptual framework based on the Theory of Reasoned Action (TRA) in understanding coming out experiences and psychological distress of 187 Chinese gay men. Results showed that participants' coming out experiences were characterized by same-sex sexual fantasy at teenage years, followed by awareness of homosexual tendency, same-sex sexual contact, and then self-identification and disclosure of homosexual orientation in young adulthood. Regarding targets of disclosure, participants tended to disclose their sexual orientation to their gay friends first, followed by heterosexual friends, siblings, parents, and coworkers. This study also supported the extension of the TRA conceptual framework to Chinese societies. Results showed that a low level of psychological distress in Chinese gay men was linked to their coming out experiences, which were in turn related to TRA components of involvement and identification with gay communities and positive attitudes toward coming out. Limitations and implications were also discussed.
