4 Vectors of Transmission

At Test Labs we are committed to research the difficult questions around infection prevention. Using our combined experience and knowledge of vectors of transmission, we always make sure that our approach considers surfaces, water, people, and air as potential routes of infection transmission.

Healthcare-Associated Infections (HAIs) are a recurring problem in the healthcare system. While there are many contributing factors, it has been widely identified that the vectors of transmission within the environment play a significant role in the spreading and transmission of infections. In addition to this well standing issue, in the last pandemic years we’ve seen the impact misguided infection control can have on infections and the pressures on healthcare staff globally.

On every project we embark ourselves into, we are committed to working with both medical device manufacturers and healthcare facilities to tackle infections considering the following four areas:

4 Vectors of Transmission


Microorganisms can survive on a variety of surfaces, and for prolonged periods of time. Through touching a contaminated surface, viruses and bacteria can be transmitted.


Water provides an environmental reservoir for many microorganisms including Legionella pneumophilia, the causative agent of Legionnaire’s disease. Transmission occurs via ingestion of contaminated water.


Transmission of infection can be airborne, in which tiny particles of an infectious agent are carried by dust or droplets in the air and inhaled into the lungs.


People provide two forms of reservoir in which a pathogen may live, flourish and multiply: as acute clinical cases or as carriers. Both present a risk of transmission to others.

By using our unique knowledge of infection prevention and control strategies, we provide valuable guidance and results for our customers:

  • For healthcare: we work with hospitals providing expertise in identifying the vectors of transmission within their environment, and in determining the efficacy of the various decontamination products and technologies commercially available.
  • For medical device manufacturers: we analyse the compatibility of medical devices, to make sure that the appropriate materials are used, ensuring product longevity and seamless integration into a healthcare environment.
  • For decontamination technology manufacturers: we test the efficacy and performance of decontamination systems in both simulated environments testing full-size systems on our state-of the art chambers, and on real life environments through clinical studies.
