Do you know what are the
3 Modes of Transmission for SARS-CoV-2?
Precaution Measures
Direct Contact
Transmission through Respiratory Droplets (>5-10μm) coughs, sneezes, talks,laughs or sings within 1 meter
Surface
Transmission through Fomite / Contaminated Surface
Airborne
Transmission spread through Aerosols particularly with poor indoor ventilation (contaminated air can be trapped & be in the environment for up 3 to16 hours)
Most methods are good for air or surface disinfection but do you know the difference & effectiveness among Air filtration, Air Disinfections & Surface Disinfections:
Do you know what are the implications of each method?
Primary
AIR FILTRATION
Portable HEPA unit increase effective ventilation rate and improved room air mixing.
Reduce the concentration of airborne particulates (as small as 0.1 μm), including
SARS-CoV-2 viral particles.
Thus give effective air exchanges without the need for conditioning outdoor air.
Electronic air filter emits ozone – to use without occupants in the room.
Secondary
AIR DISINFECTION
Minimal impact to ventilation
Mainly disinfecting microorganisms suspended in the air with short UV radiation,
ozone, ionizer or chemical substances, better without occupants in the room.
Special considerations should be made for occupants safety, particularly people with asthma. Some cleaning and disinfection products can trigger asthma.
Secondary
SURFACE DISINFECTION
Minimal impact to ventilation
Disinfecting kills any remaining germs on surfaces and reduces the spread of germs, without occupants in the room.
Special considerations should be made for people with asthma. Some cleaning and disinfection products can trigger asthma.
