Why you are much less likely to catch COVID-19 outdoors

How Fresh Air Fights Infections such as Flu and Coronaviris
You might think that going outside in the cold makes you more likely to ‘catch a cold’. But in fact, colds, the flu and COVID-19 spread much more easily inside. Let us explain …

How are infections such as Flu and Coroanvirus spread?
Both flu (and the common cold) and Coronaviruses such as COVID-19 are caused by viruses, which are spread through exposure to respiratory secretions (i.e. an infected person’s sneezes or coughs). The virus can be spread through the air, personal contact (such as a handshake), or by touching contaminated objects.

How long do these viruses remain infectious?

Virus

Hard Surfaces (e.g. desk, door handle)

Hands
​

​Indoor Air

COVID-19 (Coronavirus)

Up to 72 hours

​Several hours

Up to 3 hours

​Colds

Up to 24 hours

More than an hour

Up to 45 minutes

Flu

Up to 24 hours

Up to 10 minutes

Several hours

Respiratory Syncytial Virus (RSV) (cold-like virus that can cause serious illness in children)

Up to 6 hours

Up to 30 minutes

Several hours

​Parainfluenza (causes croup)
​

Up to 10 hours

Up to 10 minutes

Transmission unlikely

​As you can see, these can  hang around indoors for up to 72 hours – and people can shed huge numbers of cold / flu viruses into the air which can in turn settle onto surfaces: 

Coughing 
Sneezing 
Talking / Singing 
Vomiting 
Shed by Diarrhea into the air

Nature’s outdoors remedy - Hydroxyls
However, outside, you’re much less likely to catch these viruses. That’s because Hydroxyl Radicals, which occur naturally and abundantly in the air outside, kill all human pathogens on contact, including cold and flu viruses.
Hydroxyl Radicals are commonly known as ‘Nature’s Detergent’, and we think they are pretty amazing!

Only Airora's technology creates the same remedy indoors, in both the air and on surfaces.
