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.

Scientists urge provinces to take action to curb aerosol spread of COVID-19. In an open letter sent Monday, more than 300 medical and scientific experts say provinces aren't educating the public enough about the risks of COVID-19 airborne transmissions in closed spaces.

How COVID-19 Spreads

COVID-19 spreads very easily from person to person

How easily a virus spreads from person to person can vary. The virus that causes COVID-19 appears to spread more efficiently than influenza but not as efficiently as measles, which is among the most contagious viruses known to affect people.

COVID-19 most commonly spreads during close contact

      • People who are physically near (within 6 feet) a person with COVID-19 or have direct contact with that person are at greatest risk of infection.
      • When people with COVID-19 cough, sneeze, sing, talk, or breathe they produce respiratory droplets. These droplets can range in size from larger droplets (some of which are visible) to smaller droplets. Small droplets can also form particles when they dry very quickly in the airstream.
      • Infections occur mainly through exposure to respiratory droplets when a person is in close contact with someone who has COVID-19.
      • Respiratory droplets cause infection when they are inhaled or deposited on mucous membranes, such as those that line the inside of the nose and mouth.
      • As the respiratory droplets travel further from the person with COVID-19, the concentration of these droplets decreases. Larger droplets fall out of the air due to gravity. Smaller droplets and particles spread apart in the air.
      • With passing time, the amount of infectious virus in respiratory droplets also decreases.

COVID-19 can sometimes be spread by airborne transmission

      • Some infections can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours. These viruses may be able to infect people who are further than 6 feet away from the person who is infected or after that person has left the space.
      • This kind of spread is referred to as airborne transmission and is an important way that infections like tuberculosis, measles, and chicken pox are spread.
      • There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising.
        • Under these circumstances, scientists believe that the amount of infectious smaller droplet and particles produced by the people with COVID-19 became concentrated enough to spread the virus to other people. The people who were infected were in the same space during the same time or shortly after the person with COVID-19 had left.
