For the first time worldwide, the University of Florida succeeded in detecting living Sars-CoV-2 in the air and 5 meters away from the patient. This clearly proves aerosol transmission and standard ventilation in interior spaces is not enough. In addition, it was confirmed that the virus stays infectious for up to3 hours in the air.

The analysis shows that the most dangerous particles are those that are less than 0.1 µm in size - much smaller than usual aerosols (3-5 µm).

Metabolic effects of air pollution exposure and reversibility:
It has long been known that air pollution in city centers has negative effects on people. It has now been analyzed and proven by Johns Hopkins University that fine dust / car exhaust fumes lead to an increased risk of diabetes. We're exposed to that pollutants also in indoor environments, especially in big cities.

Respiratory infections occur through the transmission of virus-containing droplets (>5 to 10 μm) and aerosols (≤5 μm) exhaled from infected individuals during breathing, speaking, coughing, and sneezing.

How is the new Coronavirus transmitted from person to person?
The new Coronavirus is a respiratory virus that spreads mainly through close contact with a sick person. The primary route is the breath droplets of infected people through, for example:
- saliva, coughing and sneezing
- direct personal contacts
- hands, e.g. touching with contaminated (not yet washed) mouth, nose or eyes
What is the definition of close contact?
The "close contact" (high risk exposure) of a probable or confirmed case is defined as:
a person who has had direct (face-to-face) contact with a COVID-19 case, at a distance of less than 2 metres and at least 15 minutes
a person who has been in a closed environment (e.g. classroom, meeting room, hospital waiting room) with a COVID-19 case in the absence of suitable PPE
