BACKGROUND The increasing frequency and intensity of dengue outbreaks in endemic and non-endemic countries requires a rational, evidence based response. To this end, we aimed to collate the experiences of a number of affected countries, identify strengths and limitations in dengue surveillance, outbreak preparedness, detection and response and contribute… (More)
Early clearance (EC) is the successful eradication of inhaled Mycobacterium tuberculosis before an adaptive immune response develops. Evidence for EC comes from case contact studies that consistently show that a proportion of heavily exposed individuals do not develop M. tuberculosis infection. Further support for the existence of this phenotype comes from… (More)
Rothia aeria is a recently described Gram-positive rod from the family Micrococcaceae. An elderly woman with rheumatoid arthritis and dental abscesses who was undergoing immunosuppression had R. aeria isolated from synovial fluid. This report characterizes this rare organism and contributes to the literature on its pathogenicity and likely oral source.
Community transmission of influenza A pandemic (H1N1) 2009 was followed by high rates of hospital admissions in the Wellington region of New Zealand, particularly among Maori and Pacific Islanders. These findings may help health authorities anticipate the effects of pandemic (H1N1) 2009 in other communities.
BACKGROUND Although the burden of infectious diseases seems to be decreasing in developed countries, few national studies have measured the total incidence of these diseases. We aimed to develop and apply a robust systematic method for monitoring the epidemiology of serious infectious diseases. METHODS We did a national epidemiological study with all… (More)
Increasing rates of Clostridium difficile infection (CDI) among those without traditional risk factors have been reported mainly in Europe and North America. Here we describe the epidemiology, clinical features and ribotypes of CDI at National University Hospital (NUH), a 1000-bed tertiary care hospital in Singapore, from December 2011 to May 2012. All… (More)
In a Singapore hospital practising meticillin-resistant Staphylococcus aureus (MRSA) admission screening, the relative risk for MRSA colonization for those admitted from nursing homes was 6.89 (95% confidence interval: 5.74-8.26; 41% of 190 vs 6.0% of 14,849). However, the MRSA burden on admission attributable to nursing home residence was low (6.9%). Risk… (More)
OBJECTIVES Knowledge of the patterns of antibiotic consumption within a population provides valuable information on when, where and to whom antibiotics are prescribed. Such knowledge is critical in informing possible public health interventions to reduce inappropriate antibiotic use. The aims of this study were to (i) determine national patterns of… (More)
Dear Editor, Both dengue and acute human immunodefi ciency virus-1 (HIV-1) can cause a febrile illness associated with myalgias, rash and blood count abnormalities, as noted in a single case report.1 In Singapore, suspected cases of dengue are usually managed as outpatients without confi rmatory testing, so acute HIV-1 may be misdiagnosed.2 If routine confi… (More)
OBJECTIVES Recently published guidelines on the treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections recommend against administering vancomycin by continuous infusion on the basis of insufficient studies comparing this with intermittent infusion. We compared outcomes of patients treated with continuous infusion and intermittent… (More)
