Contact Index Monitor

How a pandemic develops depends on many factors: the biology of the pathogen, its susceptibility to external influences such as humidity and temperature, but most of all it is determined by contacts between individuals: transmissions occur primarily when people have contact with each other.

The number of contacts thus gives us an insight into the course of the pandemic. Fewer contacts make it more difficult for the pathogen to spread through the population, whereas more contacts promote rapid spread.

In the Contacts Monitor, we show the number of contacts and its variation in Germany over time.
