Simian malaria is a zoonotic disease caused by Plasmodium knowlesi infection. The common natural reservoir of the parasite is the macaque monkey and the vector is the Anopheles mosquito. Human cases of P. knowlesi infection has been reported in all South East Asian countries in the last decade, and it is currently the most common type of malaria seen in Malaysia and Brunei. Between 2007–2017, 73 cases of P. knowlesi infection were notified and confirmed to the Ministry of Health in Brunei. Of these, 15 cases (21%) were documented as work-related, and 28 other cases (38%) were classified as probably related to work (due to incomplete history). The occupations of those with probable and confirmed work related infections were border patrol officers, Armed Forces and security personnel, Department of Forestry officers, boatmen and researchers. The remaining cases classified as most likely not related to work were possibly acquired via peri-domestic transmission. The risk of this zoonotic infection extends to tourists and overseas visitors who have to travel to the jungle in the course of their work. It can be minimised with the recommended use of prophylaxis for those going on duty into the jungles, application of mosquito/insect repellants, and use of repellant impregnated uniforms and bed nets in jungle camp sites.

3.Can We Reduce Workplace Fatalities by Half?.
Safety and Health at Work 2012;3(2):104-109
Singapore, an island republic of over 5 million inhabitants, has 3.1 million workers. Most are employed in the service, finance and tourist/transport industry. Significant numbers work in manufacturing, construction and heavy industry. Following a series of construction and shipyard accidents with multiple deaths in 2004, the government announced its intention to reduce workplace fatalities from 4.9 to 2.5 per 100,000 by 2015. There was strong political will to achieve this target. The strategic approaches were to build workplace safety and health (WSH) capabilities; implement legislative changes with enforcement; promote benefits of WSH and recognize best practices, and enhance partnership with stakeholders. The anticipated outcomes were to reduce workplace fatality and injury rates; have WSH as an integral part of business; and establish a progressive and pervasive WSH culture. With these measures, the workplace fatality rate declined from 4.9/100,000 in 2004, to 2.2/100,000 in 2010. However, other confounding factors could also account for this decline, and have to be considered. The next target, announced by Singapore's Prime Minister in 2008, is to further reduce the workplace fatality rate to 1.8/100,000 by 2018, and to have "one of the best workplace safety records in the world".

Background: Young adults are at risk of developing obesity, especially when transitioninginto university life as they become responsible for their daily eating and lifestyles. This studyestimates the prevalence of overweight/obesity and explores the eating patterns and lifestylepractices of university students.Methods: A cross-sectional study was conducted at Universiti Brunei Darussalam (UBD).A total of 303 students participated. Data was collected from January to April 2016. Self-designedquestionnaires comprised questions pertaining to current weight, self-reported height data,information on eating habits, exercise and knowledge of the food pyramid. The collected datawere used to compare and contrast eating habits and lifestyle practices among overweight/obesestudents with those of non-overweight/obese students.Results: The prevalence of overweight/obesity was 28.8% (95% CI: 24.0%, 34.0%). Themajority ate regular daily meals, but more than half skipped breakfast. Frequent snacking, friedfood consumption at least three times per week and low intake of daily fruits and vegetableswere common. The frequency of visits to fast food restaurants was significantly higher in theoverweight/obese. 25.4% of the students exercised at least three times per week. Almost allstudents are aware of balanced nutrition and the food pyramid.Conclusions: Most university students had poor eating habits, although the majority hadgood nutrition knowledge. By way of recommendation, the university is encouraged to provide amulti-disciplinary team specialising in health promotion that includes nutrition and physicalactivity programmes to increase the awareness among the university students.
6.COVID-19 and Return-To-Work for the Construction Sector: Lessons From Singapore
Safety and Health at Work 2021;12(2):277-281
Singapore’s construction sector employs more than 450,000 workers. During the height of the COVID-19 pandemic in Singapore from April to June 2020, migrant workers were disproportionately affected, including many working in the construction sector. Shared accommodation and construction worksites emerged as nexuses for COVID-19 transmission. Official government resources, including COVID-19 epidemiological data, 43 advisories and 19 circulars by Singapore’s Ministries of Health and Manpower, were reviewed over 8 month period from March to October 2020. From a peak COVID-19 incidence of 1,424.6/100,000 workers in May 2020, the incidence declined to 3.7/100,000 workers by October 2020. Multilevel safe management measures were implemented to enable the phased reopening of construction worksites from July 2020. Using the Swiss cheese risk management model, the authors described the various governmental, industry, supervisory and worker-specific interventions to prevent, detect and contain COVID-19 for safe resumption of work for the construction sector.

INTRODUCTIONWith the potential threat of an avian influenza (AI) pandemic, healthcare workers (HCWs) are expected to play important roles, and they encounter significant stress levels from an expected increase in workload. We compared the concerns, perceived impact and preparedness for an AI pandemic between HCWs working in public primary care clinics and a tertiary healthcare setting.
MATERIALS AND METHODSAn anonymous, self-administered questionnaire was given to 2459 HCWs working at 18 public polyclinics (PCs) and a tertiary hospital (TH) in Singapore from March to June 2006. The questionnaire assessed work-related and non-work-related concerns, perceived impact on personal life and work as well as workplace preparedness.
RESULTSWe obtained responses from 986 PC and 873 TH HCWs (response rate: 74.6% and 76.7%). The majority in both groups were concerned about the high AI risk from their occupation (82.7%) and falling ill with AI (75.9%). 71.9% accepted the risk but 25.5% felt that they should not be looking after AI patients with 15.0% consider resigning. HCWs also felt that people would avoid them (63.5%) and their families (54.1%) during a pandemic. The majority expected an increased workload and to feel more stressed at work. For preparedness, 74.2% felt personally prepared and 83.7% felt that their workplaces were prepared for an outbreak. TH HCWs were more likely to be involved in infection-control activities but the perception of infection-control preparedness in both groups was high (>80.0%).
CONCLUSIONSHCWs in both public primary and tertiary healthcare settings felt prepared, personally and in their workplaces, for a pandemic. Their main concerns were risks of falling ill from exposure and the possibility of social ostracism of themselves and their families. Preparedness levels appeared high in the majority of HCWs. However, concerns of HCWs could affect their overall effectiveness in a pandemic and should be addressed by incorporating strategies to manage them in pandemic planning.

INTRODUCTIONDuring an avian influenza (AI) pandemic, primary-care physicians (PCPs) are expected to play key roles in the prevention and control of the disease. Different groups of PCPs could have different concerns and preparedness level. We assessed the concerns, perceived impact and preparedness for an outbreak among PCPs in Singapore.
MATERIALS AND METHODSA cross-sectional survey of PCPs working in private practice (n=200) and public clinics (n=205) from March to June 2006 with an anonymous self-administered questionnaire on concerns (12- items), perceived impact (10 items) and preparedness (10 items) for an outbreak.
RESULTSTwo hundred and eighty-five PCPs responded - 149 (response rate: 72.7%) public and 136 (response rate: 67.3%) private. The majority were concerned about risk to their health from their occupation (95.0%) and falling ill with AI (89.7%). Most (82.5%) accepted the risk and only 33 (11.8%) would consider stopping work. For perceived impact, most felt that people would avoid them (69.6%) and their families (54.1%). The majority (81.3%) expected an increased workload and feeling more stressed at work (86.9%). For preparedness, 78.7% felt personally prepared for an outbreak. Public PCPs were more likely to be involved in infection-control activities and felt that their workplaces were prepared.
CONCLUSIONSMost PCPs felt personally prepared for an outbreak but were concerned about their exposure to AI and falling ill. Other concerns included social ostracism for themselves and their families. Public PCPs appeared to have a higher level of preparation. Addressing concerns and improving level of preparedness are crucial to strengthen the primary-care response for any AI outbreak.

The majority of people diagnosed with diabetes mellitus are in the working age group in developing countries. The interrelationship of diabetes and work, that is, diabetes affecting work and work affecting diabetes, becomes an important issue for these people. Therapeutic options for the diabetic worker have been developed, and currently include various insulins, insulin sensitizers and secretagogues, incretin mimetics and enhancers, and alpha glucosidase inhibitors. Hypoglycemia and hypoglycaemic unawareness are important and unwanted treatment side effects. The risk they pose with respect to cognitive impairment can have safety implications. The understanding of the therapeutic options in the management of diabetic workers, blood glucose awareness training, and self-monitoring blood glucose will help to mitigate this risk. Employment decisions must also take into account the extent to which the jobs performed by the worker are safety sensitive. A risk assessment matrix, based on the extent to which a job is considered safety sensitive and based on the severity of the hypoglycaemia, may assist in determining one's fitness to work. Support at the workplace, such as a provision of healthy food options and arrangements for affected workers will be helpful for such workers. Arrangements include permission to carry and consume emergency sugar, flexible meal times, self-monitoring blood glucose when required, storage/disposal facilities for medicine such as insulin and needles, time off for medical appointments, and structured self-help programs.
