HUMAN TRANSMISSION
Transmission of germs by humans can take place in many different ways.
One of the most important is the droplet infection: Tiny, pathogen-containing water droplets are blown into the air when speaking, sneezing or coughing - viruses and bacteria travel this way from person to person.
Other transmission options are smear infection, direct blood contact or sexual intercourse.
The hands are the most common carriers, so door handles, for example, are contaminated accordingly.
