Infection control in care homes is important because people are living in close proximity within a care home and there are also many people (staff, visitors) coming and going from outside. Care home residents are usually elderly and frail, both of which can undermine immunity. An infection which a young person can easily throw off may take hold in an older person.
The two types of infection that are most common in care homes are respiratory tract infections and gastrointestinal infections. These may be either viral or bacterial. Among respiratory tract infections, most of common pathogens found in the care home environment are:
We know that there are four main ways in which these respiratory infections are transmitted from an infected person.
1. Airborne transmission via droplets. Coughing, sneezing, or even just talking may generate droplets more than 5 microns in size. These may lead to infection if the droplets come into contact with the eyes or nose of a vulnerable person (i.e., a care home resident). These droplets are relatively large and do not stay airborne for more than about one metre before they settle on a surface.
2. Aerosol transmission. This is essential for airborne infection control, as airborne transmission takes place when droplets less than 5 microns in size are created and remain suspended in the air. This can sometimes occur during medical procedures, such as putting in a feeding tube or a catheter or chest physiotherapy for lung conditions. These droplets can be dispersed widely by air currents, because they are so light, and cause infection by inhalation.
3. Direct contact. This occurs during skin-to-skin or oral contact. Organisms may be passed directly to the hands of a vulnerable individual who then transfers the organisms into their nose, mouth or eyes if they touch their face.
4. Indirect contact transmission. This will occur if a vulnerable individual touches a contaminated surface or object and then transfers the organisms to their mouth, nose or eyes.
Meanwhile, gastrointestinal infections are usually characterised by diarrhoea and vomiting. Pathogens, including the notorious Clostridium difficile (C.diff) and the highly contagious norovirus, can be spread through the care home as follows:
We also know that gastrointestinal viruses can be spread by:
The spread of infection in a care home can be prevented in a number of ways.

There are a wide range of systems available on the market that show differing levels of efficacy in capturing airborne viruses and bacteria. But which class of HEPA filters – H13 vs H14 filtration – have a higher long-term efficacy?
In this post, we provide an overview of why air filtration is an important measure to mitigate the risk of airborne contamination and airborne viral transmission, how HEPA filters can reduce this risk, and which class - H13 vs H14 filtration – has shown the highest overall efficacy in achieving this.
Here we explore the benefits of adopting air filtration and purification systems in school classrooms, alongside recommended measures such as social distancing, hand washing and face mask use. Effective air filtration can help provide protection against Covid-19 and improve indoor air quality more broadly.
