Virus WAtch Week Ending 16 August 2015 Influenza and Influenza-like Illnesses (ILI) Summary: Indicators of influenza activity remain relatively steady, suggesting we are around the peak of the influenza season. Non-influenza virus activity continues to decline. ILI presentations to sentinel general practitioners (GPs) and emergency departments (EDs) remain relatively steady and within ranges seen in mild influenza seasons. Influenza virus detections, notifications and percent positivity appear to have plateaued. Influenza B virus (57% of detections) continues to predominate, but appears […]

Virus WAtch Week Ending 9 August 2015 Influenza and Influenza-like Illnesses (ILI) Summary: Indicators of influenza activity remain relatively steady, indicating we may be at or near the peak of the influenza season. Non-influenza virus activity continues to decline. ILI presentations to sentinel general practitioners (GPs) and emergency departments (EDs) have plateaued. Influenza virus detections and notifications have plateaued, but percent positivity increased this week. Influenza B virus (61% of detections) continues to predominate, but is gradually declining in relative […]

Virus WAtch Week Ending 2 August 2015 Influenza and Influenza-like Illnesses (ILI) Summary: Indicators of influenza activity remain relatively steady, indicating we may be at or near the peak of the influenza season. Non-influenza virus activity continues to decline. ILI presentations to sentinel general practitioners (GPs) and emergency departments (EDs) increased slightly this week but appear to have plateaued. Influenza virus detections, notifications and percent positivity remain stable. The number and proportion of detections due to influenza B (63%) declined […]

Infection prevention and control in residential and community aged care is a pocket book developed by the National Health and Medical Research Council (NHMRC) and the Department of Health https://www.nhmrc.gov.au/guidelines-publications/d1034 The pocket book provides information on the key principles of infection prevention and control for the residential aged care (RAC) and community aged care (CAC) community.  It provides advice to Assistants in Nursing, Community Care Assistants, Personal Care Workers and ancillary staff about integrating the principles of infection prevention and […]

Virus WAtch Week Ending 26 July 2015 Influenza and Influenza-like Illnesses (ILI) Summary: Taken together, direct and indirect indicators suggest that influenza virus activity may have now peaked, earlier than in recent seasons. Non-influenza virus activity also declined this week. ILI presentations to sentinel general practitioners (GPs) decreased this week and presentations to sentinel emergency departments (EDs) were steady. Influenza virus detections, notifications and percent positivity appear to have reached a peak. Influenza B (68%) and influenza A/H3N2 (29%) viruses […]

Virus WAtch Week Ending 19 July 2015 Influenza and Influenza-like Illnesses (ILI) Summary: Non-influenza virus activity, particularly respiratory syncytial virus (RSV), remains high. Influenza activity, primarily due to influenza B virus, remains moderate in intensity. ILI presentations to sentinel general practitioners (GPs) increased this week, but conversely presentations to sentinel emergency departments (EDs) decreased. Influenza virus detections and notifications decreased for the second consecutive week, while percent positivity has fluctuated at around 20% over recent weeks. Hospitalisations with confirmed influenza […]

Virus WAtch Week Ending 12 July 2015 Influenza and Influenza-like Illnesses (ILI) Summary: ILI activity and influenza virus detections decreased this week, but seasonal activity is on-going. ILI presentations to sentinel emergency departments (EDs) and sentinel general practitioners (GPs) decreased this week, possibly a school holiday effect. Hospitalisations with confirmed influenza have been relatively steady over recent weeks, at around 10 per 1000 admissions, over 50% due to influenza B virus. Influenza B viruses (69%) and influenza A/H3N2 (26%) viruses […]

Virus WAtch Week Ending 5 July 2015 Influenza and Influenza-like Illnesses (ILI) Summary: ILI activity and more direct indicators of influenza virus activity all increased this week, indicating influenza season has commenced. ILI presentations to sentinel emergency departments (EDs) and sentinel general practitioners (GPs) increased this week. Hospitalisations with confirmed influenza have been relatively steady over recent weeks, at around 10 per 1000 admissions. Influenza virus detections, notifications and test positivity rate in both sentinel and routinely collected specimens all […]

Virus WAtch Week Ending 28 June 2015 Influenza and Influenza-like Illnesses (ILI) Summary: Rates of influenza-like illness increased this week. ILI presentations to sentinel emergency departments (EDs) and sentinel general practitioners (GPs) increased this week. Hospitalisations with confirmed influenza have been relatively steady over recent weeks, at around 10 per 1000 admissions. Influenza virus detections, test positivity and notifications are have changed little in the past few weeks, with influenza B viruses (75%) and influenza A/H3N2 (20%) viruses dominating detections; […]

Surgical site infection (SSI) is a major complication following surgery and is associated with increased morbidity and mortality, as well as increased costs. The function of operating room (OR) ventilation is to prevent airborne microbial contaminants from entering surgical wounds. Under normal circumstances, the main source of airborne microbial contamination is microscopic skin fragments, contaminated with bacteria, shed by healthcare workers (HCWs) in the OR. Another potential source of airborne microorganisms are air supplies that are not properly filtered. The […]
