control: virus protection, IAQ and care homes
As the Indoor Air Quality (IAQ) debate takes on ever greater significance and dominates headlines during the pandemic, John Barker, managing director of Humidity Solutions, examines the research on the role humidity control can play, and looks at some of the solutions for care homes, hospitals and places of work
learly, since the global pandemic of COVID-19, the emphasis on infection control has become of utmost importance, in particular in care homes and hospitals and how best to assist with limiting the transmission of airborne viruses within these establishments.
This is part of the greater discussion around IAQ and how we can protect people who are working, studying or being cared for in increasingly airtight buildings for the majority of their day.
Research and data
Scientific data does show that to maintain a humidity of 50% relative humidity (RH) will reduce the transmission of viruses by keeping the bodies defence mechanism (mucus membrane in the nose and throat) moist and able to capture airborne bacteria and virus before it enters the body. Maintaining an RH of between 30-60% has been shown to influence the survivorship of viruses and reduce the transmission and infectiousness of viral diseases.
More recent studies have taken aim at the influence of RH on specific families of viruses, like influenza and coronavirus. These studies focus on the observed survival on surfaces and in the air
