Even if more and more people make a big bow to public transport, to stay on for some indispensable.
Including the Hamburger, Dr. Armin Hauck, the need to commute in spite of the Corona-crisis daily to his work.
In the ‘Hamburger Morgenpost’ explains the eye doctor now, what is the health risk, it struck him in particular – and the extent to which the Phone is.
Higher risk of droplet infection?
The 1.5 Meter distance rule has especially a Background: to protect people from infection with the Coronavirus by droplet infection.
Such a risk is given mainly by Sneezing or coughing of an infected Person. A fact, which is now sufficiently known.
Obviously, the risk of the go from the Talk, will be underestimated, however, Dr. Armin Hauck explains in an interview with the ‘Mopo’.
“A kind of droplet cloud, in closed rooms up to three hours,“ said the doctor formed around us.
“For local public transport in the HVV users (Hamburg transport Association, note should.d.Editorial), be aware that the risk of infection is greater if you are on a call.“
How does the infection with corona virus?
In the case of a droplet infectious disease pathogens enter through tiny saliva droplets in the air and are then inhaled by another person.
Depending on the size of the droplets for two types to be distinguished, which can make pathogens to the Transmission advantage:
- Larger droplets with a diameter of more than 5 microns, These are relatively heavy and sink in the air therefore quickly. Thus, diseases can be transmitted only up to a distance of about one Meter. Therefore, the distance of 1.5 meters to other people is so important.
- Droplets of much smaller size (< 5 µm) that can remain by your spring weight for a long time to hang in the air and so-called aerosols, droplets, clouds can form over long distances infectious.

Coronaviruses should be able to use not only the first but also the second path via smaller droplets to disease transmission, would be using the Phone in public transport, in fact, an increased risk for other passengers.
Reasons against the use of the Phone in Bus and train
An English study estimated that can at least not be excluded that the Coronavirus Sars-CoV-2 could also be aerosol transmitted.
According to the Robert Koch-Institute, there has been but as yet no recorded case of infection through aerosols.
One way or the other but there is another reason why excessive Talking – whether on the phone or to other passengers – with inherent risks.
The droplets can remain on objects and surfaces within a radius of one Meter, and so, in fact, a risk of infection for other present guests.
