Contamination
As prevalence , even infection prevalence called is called the diffusion rate of endemic infectious disease in a population at a given time. This also includes cases among the previously ill individuals in the population in which the signs of the disease were not noticed or were not associated with the disease, for example as a cause of a miscarriage . It also varies from disease to disease whether temporary or permanent immunity has been achieved.
In the case of herpes simplex virus 1 , an infection rate of 95% worldwide is assumed in adults. In the case of three-day fever , it is assumed that it is over 95% by the age of two. The Helicobacter infection rate in Germany is currently around 40% among those over 40 years of age. In zoology , the contamination of animal species is of particular interest if the disease can also be transmitted to humans. For example, the infection of foxes with the fox tapeworm in Bavaria and Swabia is on average 29% to 55%, the infection of ticks with Borrelia 5 to 35 percent.
