How Infections Are Transmitted

There are four main methods in which infections are transmitted, they are:

FOOD
Food infection control

Controlled by:

  • Food hygiene practices
CONTACT
Contact infection control

Controlled by:

  • Hand washing
  • PPE
OBJECTS
Objects infection control

Controlled by:

  • Cleaning
AIRBORNE

The Problem

AIRBORNE TRANSMISSION

Woman sneezing

DROPLET TRANSMISSION

Large droplets will only be propelled a short distances (2m) through the air, They will however then settle on surfaces and can become airborne again from natural air currents created from activity in the room. Furthermore evaporation of the droplet will make them smaller called droplet nuclei, placing them in a state where they can re-infect a susceptible host.

Airborne aerosols

AEROSOLS

Also released by coughing and sneezing there are much smaller droplets which are light enough to float.  They can move over longer distances and stay airborne for longer periods. These droplets will be widely dispersed by air currents before being inhaled, or deposited on surfaces, equipment etc.

CURRENT SOLUTIONS

Ventilate the room

Open windows

Lower temperatures

Turn down heating

Modify air conditioning to increase to percentage of fresh air

Investigate with maintenance teams

Still a problem?

If you have rooms that are small, kept above average temperature and heavily used?

A UV air steriliser1 is a plug and play solution

Summary of disinfection technologies for microbial control.
Germicidal UV (GUV) is a technology that could be beneficial for decontamination and reducing aerosol concentrations in some occupied environments.

HOW MEDIXAIR WILL EFFECTIVELY CONTROL AIRBORNE TRANSMISSION

Medixair air cleaning process

Air drawn through medixair’s chamber at a controlled speed

Airborne pathogens are exposed to high levels of UVc radiation

COVERAGE

Medixair coverage
  • Covers 25m2 area
  • Whisper quiet
  • No ozone produced
  • 90W power consumption
  • Wall mount or mobile stand options available

A single Medixair unit will emit 25m3 of sterilised air per hour

Medixair can provide differing levels of protection against aerobiological contamination, providing an air changes every hour, or every two or three hours as required. 

The level of protection provided may be adjusted by varying the number of units installed in any given space. 

Unless there is a reason to do otherwise (i.e. an extreme level of risk) we recommend one machine to treat 75m3.

Therefore, with a typical room height of approximately 2.5 m this would equate to a floor area of 30m2. (75m3/2.5m).  

For example, a 6m x 5m room.
