Description:
The role of poorly maintained ventilation ductwork in spreading airborne infections is largely ignored because it is ‘out of sight out of mind’, but recent analysis by healthcare professionals confirms that the risks are increasing.
Ghasson Shabha will identify particular threats in healthcare facilities from dirty ductwork. He also points out that fewer than 5% of building air-conditioning systems have been inspected despite regulations making this mandatory. Dr Shabha will look at how planned cleaning strategies can reduce risks and how hospitals can use 3D building information modelling software to identify ‘infection hotspots’.
The healthcare environment can be described as a reservoir for potentially infective agents which can spread unpredictably in a whole array of ways particularly in ventilation and air-conditioning systems making it difficult to effectively control and manage, for those seeking timely information about the patterns of cross-infection. The severity of the problem has been highlighted extensively over the past decade, as part of wider umbrella of what was known as health care acquired infections (HCAIs). Airborne transmission extends over a wide spectrum, and includes many prevalent agents, inter alia Mycobacterium tuberculosis (TB),nosocomial MRSA, Aspergillus fumigatus, Serratia marcescens, norovirus, and other airborne infection.
Dr Shabha was speaking live from Birmingham and this CIBSE ASHRAE Group (cibseashrae.org) webinar was co-sponsored by the B&ES Ventilation Hygiene Group and the Institute of Healthcare Engineering and Estate Management (IHEEM).

Title
Description
-
This patient had severe kyphoscoliosis as a child with insertion of spinal rods in early adulthood. She is a life-long non-smoker. She first presented in 2001 with an irritating cough and several treatments with antibiotics failed to alleviate it.Aspergillus precipitin titre was high and she was initially diagnosed with chronic pulmonary aspergillosis with one cavity containing an aspergilloma. This patient developed resistance to all azole therapies.

Immunodiffusion technique to test for serum antibodies in patients – describes how to set up a test for the presence of antibodies in serum which are specific to various fungal pathogens. The technique is used to test and measure titres of these antibodies in the serum of infected patients.

21-year-old medical student Jo Armstead has made a major discovery, which will help doctors better able to diagnose and treat patients with Cystic Fibrosis (CF). Jo spent hundreds of hours accessing data from 30 countries to discover that there are over 75,000 people with the genetic disorder, of whom half are over 18 years – with 50 per cent infected by the fungus, Aspergillus. Professor David Denning, Director of the NHS National Aspergillosis Centre and Professor of Infectious Diseases in Global Health at the University of Manchester explains: “The life expectancy of people with CF has been increasing, but aspergillosis has a major negative impact on many. By painstakingly crunching the numbers, Jo has helped us better understand the scale of the challenge which will lead to better diagnostics and treatment strategies.” Prof Denning and Jo were interviewed on BBC-1 Breakfast last Sunday June 29th.

Fungi are eukaryotic organisms which possess a unique cell wall and cell membrane that can serve as targets for antifungal agents. The echinocandin class of antifungal agents target the cell wall of fungi. Watch this animation for more information.
